Update to v106r55 release.
byuu says:
Everything *should* be working again, but of course that won't
actually be the case. Here's where things stand:
- bsnes, higan, icarus, and genius compile and run fine on FreeBSD
with GTK
- ruby video and audio drivers are untested on Windows, macOS, and
Linux
- hiro is untested on macOS
- bsnes' status bar is not showing up properly with hiro/qt
- bsnes and higan's about screen is not showing up properly with
hiro/qt (1x1 window size)
- bsnes on Windows crashes often when saving states, and I'm not sure
why ... it happens inside Encode::RLE
- bsnes on Windows crashes with ruby.input.windows (unsure why)
- bsnes on Windows fails to show the verified emblem on the status bar
properly
- hiro on Windows flickers when changing tabs
To build the Windows bsnes and higan ports, use
ruby="video.gdi audio.directsound"
Compilation error logs for Linux will help me fix the inevitable list of
typos there. I can fix the typos on other platforms, I just haven't
gotten to it yet.

Update to v106r54 release.
byuu says: Changes to hiro will break all but the GTK target. Not that it matters much given that the only ruby drivers that function are all on BSD anyway. But if you are fortunate enough to be able to run this ... you'll find lots of polishing improvements to the bsnes GUI. I posted some screenshots on Twitter, if anyone were interested. |

Update to v106r53 release.
byuu says: Okay, so the WIPs-within-WIPs thing wasn't achieving its desired effect, and it ended up causing me to have to redo some work on hiro since my last local snapshot was of r52. So, heck it. I'll just do mostly non-functional WIPs for a bit, and worry about the fallout years later when I'm trying to find an emulation regression and cursing that the WIPs aren't compiling. I ported all of the ruby input drivers to the new syntax, as well as the OpenAL driver. If you patch the ruby drivers for Linux with this in mind, bsnes should compile and run there again. Also, the bsnes program icon has returned, now that the new hiro layout code is mature enough and I can simply add and remove the icon as a Canvas instead of having to try and render into a viewport. The icon shows up instantly with the main window. |

Update to 20180730 release.
byuu says: These WIPs-within-WIPs are getting more and more broken ... this isn't going the way I wanted. But ... this time around, I've revamped the entire ruby API again, to solve a bunch of tough problems that have always made using ruby really clunky. But there are *so many* ruby drivers that it's going to take a long time to work through them all. This WIP is only going to run bsnes, and only on FreeBSD, and only with some drivers. hiro's Application::initialize() now calls hiro::initialize(), which you define inside of your hiro apps. This lets you call Application::setName(...) before anything else in hiro runs. This is essential on Xorg to set program icons, for instance. With the ruby rewrite and the change to hiro, I can get away from the need to make everything in bsnes/higan pointers to objects, and can now just declare them as regular objects. |

Update to 20180729 release.
byuu wrote: Sigh ... asio.hpp needs #include <nall/windows/registry.hpp> [Since the last WIP, byuu also posted the following message. -Ed.] ruby drivers have all been updated (but not tested outside of BSD), and I redesigned the settings window. The driver functionality all exists on a new "Drivers" panel, the emulator/hack settings go to a "Configuration" panel, and the video/audio panels lose driver settings. As does the settings menu and its synchronize options. I want to start pushing toward a v107 release. Critically, I will need DirectSound and ALSA to support dynamic rate control. I'd also like to eliminate the other system manifest.bml files. I need to update the cheat code database format, and bundle at least a few quark shaders -- although I still need to default to Direct3D on Windows. Turbo keys would be nice, if it's not too much effort. Aside from netplay, it's the last significant feature I'm missing. I think for v107, higan is going to be a bit rough around the edges compared to bsnes. And I don't think it's practical to finish the bsnes localization support. I'm thinking we probably want another WIP to iron out any critical issues, but this time there should be a feature freeze with the next WIP. |

Update to 20180728 release.
byuu says: Sigh, I seem to be spiraling a bit here ... but the work is very important. Hopefully I can get a solid WIP together soon. But for now... I've integrated dynamic rate control into ruby::Audio via setDynamic(bool) for now. It's very demanding, as you would expect. When it's not in use, I realized the OSS driver's performance was pretty bad due to calling write() for every sample for every channel. I implemented a tiny 256-sample buffer and bsnes went from 290fps to 330fps on my FreeBSD desktop. It may be possible to do the same buffering with DRC, but for now, I'm not doing so, and adjusting the audio input frequency on every sample. I also added ruby::Video::setFlush(bool), which is available only in the OpenGL drivers, and this causes glFinish() to be called after swapping display buffers. I really couldn't think of a good name for this, "hard GPU sync" sounds kind of silly. In my view, flush is what commits queued events. Eg fflush(). OpenGL of course treats glFlush differently (I really don't even know what the point of it is even after reading the manual ...), and then has glFinish ... meh, whatever. It's setFlush(bool) until I come up with something better. Also as expected, this one's a big hit to performance. To implement the DRC, I started putting helper functions into the ruby video/audio/input core classes. And then the XVideo driver started crashing. It took hours and hours and hours to track down the problem: you have to clear XSetWindowAttributes to zero before calling XCreateWindow. No amount of `--sync`, `gdb break gdk_x_error`, `-Og`, etc will make Xlib be even remotely helpful in debugging errors like this. The GLX, GLX2, and XVideo drivers basically worked by chance before. If the stack frame had the right memory cleared, it worked. Otherwise it'd crash with BadValue, and my changing things broke that condition on the XVideo driver. So this has been fixed in all three now. Once XVideo was running again, I realized that non-power of two video sizes were completely broken for the YUV formats. It took a while, but I managed to fix all of that as well. At this point, most of ruby is going to be broken outside of FreeBSD, as I still need to finish updating all the drivers. |

Update to v106r50 release.
byuu says:
Changelog:
- emulator/video,audio: various cleanups
- emulator/audio: removed reverb effect (it breaks very badly on
high-frequency systems)
- emulator/audio: the Nyquist anti-aliasing lowpass filter is now
generated automatically instead of set per-core
- at 44.1KHz output, it's set to 22KHz; at 48KHz, it's set to
22KHz; at 96KHz, it's set to 25KHz
- this filter now takes the bsnes emulation speed setting into
account
- all system/video.cpp files removed; inlined in System::power() and
Interface::set() instead
- sfc/cpu: pre-compute `HTIME` as `HTIME+1<<2` for faster comparisons of
HIRQs
- sfc/cpu: re-add check to block IRQs on the last dot of each frame
(minor speed hit)
- hiro/gtk3: fixed headers for Linux compilation finally
- hiro/gtk,qt: fixed settings.cpp logic so initial values are used
when no settings.bml file exists
- hiro/gtk: started a minor experiment to specify theming information
in settings.bml files
- nall/dsp: allow the precision type (double) to be overridden (to
float)
- nall: add some helpers for generating pre-compiled headers
- it was a failure to try using them for higan, however ...
- nall: add some helpers for reading fallback values from empty
`Markup::Node[search]` statements
Todo:
- CRITICAL: a lot of my IRQ/NMI/HDMA timing tests are failing with the
fast PPU ... need to figure out why
- space between Emulator::video functions and Emulator::audio
functions in gb/system/system.cpp
- remove Audio/Reverb/Enable from settings.bml in target-bsnes

Update to v106r49 release.
byuu says:
This is a fairly radical WIP with extreme changes to lots of very
important parts.
The result is a ~7% emulation speedup (with bsnes, unsure how much it
helps higan), but it's quite possible there are regressions. As such, I
would really appreciate testing as many games as possible ... especially
the old finnicky games that had issues with DMA and/or interrupts.
One thing to note is that I removed an edge case test that suppresses
IRQs from firing on the very last dot of every field, which is a
behavior I've verified on real hardware in the past. I feel that the
main interrupt polling function (the hottest portion of the entire
emulator) is not the appropriate place for it, and I should instead
factor it into assignment of NMITIMEN/VTIME/HTIME using the new
io.irqEnable (==virqEnable||hirqEnable) flag. But since I haven't done
that yet ... there's an old IRQ test ROM of mine that'll fail for this
WIP. No commercial games will ever rely on this, so it's fine for
testing.
Changelog:
- sfc/cpu.smp: inlined the global status functions
- sfc/cpu: added readRAM, writeRAM to use a function pointer instead
of a lambda for WRAM access
- sfc/cpu,smp,ppu/counter: updated reset functionality to new style
using class inline initializers
- sfc/cpu: fixed power(false) to invoke the reset vector properly
- sfc/cpu: completely rewrote DMA handling to have per-channel
functions
- sfc/cpu: removed unused joylatch(), io.joypadStrobeLatch
- sfc/cpu: cleaned up io.cpp handlers
- sfc/cpu: simplified interrupt polling code using
nall::boolean::flip(),raise(),lower() functions
- sfc/ppu/counter: cleaned up the class significantly and also
optimized things for efficiency
- sfc/ppu/counter: emulated PAL 1368-clock long scanline when
interlace=1, field=1, vcounter=311
- sfc/smp: factored out the I/O and port handlers to io.cpp

Update to v106r48 release.
byuu says:
The problems with the Windows and Qt4 ports have all been resolved,
although there's a fairly gross hack on a few Qt widgets to not destruct
once Application::quit() is called to avoid a double free crash (I'm
unsure where Qt is destructing the widgets internally.) The Cocoa port
compiles again at least, though it's bound to have endless problems. I
improved the Label painting in the GTK ports, which fixes the background
color on labels inside TabFrame widgets.
I've optimized the Makefile system even further.
I added a "redo state" command to bsnes, which is created whenever you
load the undo state. There are also hotkeys for both now, although I
don't think they're really something you want to map hotkeys to.
I moved the nall::Locale object inside hiro::Application, so that it can
be used to translate the BrowserDialog and MessageDialog window strings.
I improved the Super Game Boy emulation of `MLT_REQ`, fixing Pokemon
Yellow's custom border and probably more stuff.
Lots of other small fixes and improvements. Things are finally stable
once again after the harrowing layout redesign catastrophe.
Errata:
- ICD::joypID should be set to 3 on reset(). joypWrite() may as well
take uint1 instead of bool.
- hiro/Qt: remove pWindow::setMaximumSize() comment; found a
workaround for it
- nall/GNUmakefile: don't set object.path if it's already set (allow
overrides before including the file)

Update to v106r47 release.
byuu says:
This is probably the largest code-change diff I've done in years.
I spent four days working 10-16 hours a day reworking layouts in hiro
completely.
The result is we now have TableLayout, which will allow for better
horizontal+vertical combined alignment.
Windows, GTK2, and now GTK3 are fully supported.
Windows is getting the initial window geometry wrong by a bit.
GTK2 and GTK3 work perfectly. I basically abandoned trying to detect
resize signals, and instead keep a list of all hiro windows that are
allocated, and every time the main loop runs, it will query all of them
to see if they've been resized. I'm disgusted that I have to do this,
but after fighting with GTK for years, I'm about sick of it. GTK was
doing this crazy thing where it would trigger another size-allocate
inside of a previous size-allocate, and so my layouts would be halfway
through resizing all the widgets, and then the size-allocate would kick
off another one. That would end up leaving the rest of the first layout
loop with bad widget sizes. And if I detected a second re-entry and
blocked it, then the entire window would end up with the older geometry.
I started trying to build a message queue system to allow the second
layout resize to occur after the first one completed, but this was just
too much madness, so I went with the simpler solution.
Qt4 has some geometry problems, and doesn't show tab frame layouts
properly yet.
Qt5 causes an ICE error and tanks my entire Xorg display server, so ...
something is seriously wrong there, and it's not hiro's fault. Creating
a dummy Qt5 application without even using hiro, just int main() {
TestObject object; } with object performing a dynamic\_cast to a derived
type segfaults. Memory is getting corrupted where GCC allocates the
vtables for classes, just by linking in Qt. Could be somehow related to
the -fPIC requirement that only Qt5 has ... could just be that FreeBSD
10.1 has a buggy implementation of Qt5. I don't know. It's beyond my
ability to debug, so this one's going to stay broken.
The Cocoa port is busted. I'll fix it up to compile again, but that's
about all I'm going to do.
Many optimizations mean bsnes and higan open faster. GTK2 and GTK3 both
resize windows very quickly now.
higan crashes when you load a game, so that's not good. bsnes works
though.
bsnes also has the start of a localization engine now. Still a long way
to go.
The makefiles received a rather substantial restructuring. Including the
ruby and hiro makefiles will add the necessary compilation rules for
you, which also means that moc will run for the qt4 and qt5 targets, and
windres will run for the Windows targets.

Update to v106r33 release.
byuu says:
Changelog:
- nall/GNUmakefile: added `openmp=(true,false)` option; can be toggled
when building higan/bsnes
- defaults to disabled on macOS, because Xcode doesn't stupidly
doesn't ship with support for it
- higan/GNUmakefile: forgot to switch target,profile back from
bsnes,fast to higan,accurate
- this is just gonna happen from time to time, sorry
- sfc/dsp: when using the fast profile, the DSP syncs per sample
instead of per clock
- should only negatively impact Koushien 2, but is a fairly
significant speedup otherwise
- sfc/ppc,ppu-fast: optimized the code a bit (ppu 130fps to 133fps)
- sfc/ppu-fast: basic vertical mosaic support (not accurate, but
should look okay hopefully)
- sfc/ppu-fast: added missing mode7 hflip support
- sfc/ppu-fast: added support to render at 256-width and/or 240-height
- gives a decent speed boost, and also allows all of the older
quark shaders to work nicely again
- it does violate the contract of Emulator::Interface, but oh
well, it works fine in the bsnes GUI
- sfc/ppu-fast: use cached CGRAM values for mode7 and sprites
- sfc/ppu-fast: use global range/time over flags in object rendering
- may not actually work as we intended since it's a race condition
even if it's only ORing the flags
- really don't want to have to make those variables atomic if I
don't have to
- sfc/ppu-fast: should fully support interlace and overscan modes now
- hiro/cocoa: updated macOS Gatekeeper disable support to work on
10.13+
- ruby: forgot to fix macOS input driver, sorry
- nall/GNUmakefile: if uname is present, then just default to rm
instead of del (fixes Msys)
Note: blur emulation option will break pretty badly in 256x240 output
mode. I'll fix it later.

Update to v106r27 release.
byuu says:
Changelog:
- nall: merged Path::config() and Path::local() to Path::userData()
- ~/.local/share or %appdata or ~/Library/ApplicationSupport
- higan, bsnes: render main window icon onto viewport instead of
canvas
- should hopefully fix a brief flickering glitch that appears on
Windows
- icarus: improved Super Famicom heuristics for Starfox / Starwing RAM
- ruby/Direct3D: handle viewport size changes in lock() instead of
output()
- fixes icon disappearing when resizing main window
- hiro/Windows: remove WS_DISABLED from StatusBar to fix window
resize grip
- this is experimental: I initially used WS_DISABLED to work
around a focus bug
- yet trying things now, said bug seems(?) to have gone away at
some point ...
- bsnes: added advanced settings panel with real-time driver change
support
I'd like feedback on the real-time driver change, for possible
consideration into adding this to higan as well.
Some drivers just crash, it's a fact of life. The ASIO driver in
particular likes to crash inside the driver itself, without any error
messages ever returned to try and catch.
When you try to change a driver with a game loaded, it gives you a scary
warning, asking if you want to proceed.
When you change a driver, it sets a crash flag, and if the driver
crashes while initializing, then restarting bsnes will disable the
errant driver. If it fails in a recoverable way, then it sets the driver
to “None” and warns you that the driver cannot be used.
What I'm thinking of further adding is to call emulator→save() to
write out the save RAM contents beforehand (although the periodic
auto-saving RAM will handle this anyway when it's enabled), and possibly
it might be wise to capture an emulator save state, although those can't
be taken without advancing the emulator to the next frame, so that might
not be a good idea.
I'm also thinking we should show some kind of message somewhere when a
driver is set to “None”. The status bar can be hidden, so perhaps on the
title bar? Or maybe just a warning on startup that a driver is set to
“None”.

byuu says: Changelog: - Super Game Boy: fixed loading of boot ROM - hiro: added ComboEdit::setEditable(bool = true); - tomoko: added new systems settings panel Note!!: this release will not compile on Windows or macOS due to the missing ComboEdit control! I'll try to merge in hex's implementation for the Windows release here soon. macOS users will probably be out of luck for a while, sorry. The new systems panel is an idea I've been meaning to implement for quite a while, but finally got around to starting on it. It's still fairly unpolished, but the basic idea is there for Linux/BSD users to try out now. So imagine the Super Game Boy, BS-X Satellaview, Sufami Turbo, and the associated BS Memory Pack-slotted SNES cartridges. To play any of those, you needed to choose Nintendo→Super Famicom, and then select the relevant cartridge, and then select any slotted cartridges to play with it. This was acceptable-ish, if not ideal. But now imagine in the future if we wanted to support the Famicom Disk System, which is technically a cartridge that plugs into the Famicom deck. Or the PC Engine CD, which has one of three special HuCards that must be inserted (ignoring the Turbo Duo where it's built-in—I'm going to be emulating the Super CD as if you're using a stock PCE CD.) Or the Mega CD, where there are probably a half dozen or more BIOS + hardware revisions that are region-specific, which connect to an expansion port that is identical to the cartridge port save for the Mega Drive seeing an I/O register bit toggled here. In all of these cases, it's going to be a real pain to have to choose the 'BIOS' every time you want to play a game for them. I can't distribute these BIOSes with higan due to copyright restrictions, and trying to ship dummy folders for every possible combination would become quite odious, and difficult for people to use (compare to setting up the Game Boy Advance system BIOS.) And so I've created the new systems settings panel. Here, you can manage a list of systems that show up under the higan library menu (now renamed to “System”), where each entry contains name, boot, and hidden parameters. The name parameter is what shows up in the system menu. You can call any system higan emulates whatever you like here. Don't like “Super Famicom”? Change it to “SNES”, then. The boot parameter is a combo edit with a dropdown for all of the systems higan emulates. If you choose one of these, then the higan system menu option will work exactly like in previous releases, and prompt you for a cartridge. But if you choose the browse button next to the combo edit control, you'll get to pick any gamepak from the higan library of your choosing. So you could choose the SGB2 BIOS, and name the menu option “Super Game Boy 2”, and when you choose the menu option, it will load the SFC core, load the SGB2 BIOS, and only prompt you for the Game Boy game you wish to play on it. The same deal goes for the FDS, PCE-CD, Mega CD, Mega Drive Sonic & Knuckles lock-on cartridge, BS-X Satellaview, SD Gundam G-Next, etc. Whatever you want to be in the menu, you can put in there by pointing higan at the appropriate 'BIOS' gamepak to load. Astute readers have probably already noticed, but you can technically use this on non-slotted games as well, thus creating instant boot options for your absolute favorite games, if you so wanted. Point it at Zelda 3, and you can boot it instantly from the main menu, without any need for file selection. The hidden option is a way to hide the system entries from the system menu. Primarily this would be a fast way for users to disable emulation cores they never use in higan, without having to remove the options. The major concession with this change is the collapsing of the per-manufacturer submenus. What this means is you will now have all twelve higan emulated systems in the main menu by default. This makes the list rather long, but ... oh well. I may try to offer some form of grouping in the future, but the grouping defeats the “list order = display order” design, and I'm not willing to auto-sort the list. I want people to be able to control the ordering of the system menu, and have added (as yet non-functional) sorting arrows for that purpose. I also don't have a combined tree+table view widget in higan to try to and group things. But ... we'll see how things go in the future. Another idea is to add a specialty load option that opens up the user's Emulation library path, and lets you pick a gamepak for any system, which would boot the same way as when you drop a gamepak onto the higan executable or main window. So say you almost never play Wonderswan games, this would be a way to play them without them cluttering your system menu list. The “import ROM files” option has been removed. All it does is launch icarus directly. I would rather users become familiar with using icarus. The “load ROM file” option remains. Anyway, this is all still a work in progress, so please give it time and don't overload me with too many suggested changes right now, thanks :3 |

Update to v106r14 release.
byuu says:
Changelog:
- game/memory/type/battery → game/memory/volatile
- (manufacturer.)content.type → (architecture.)content.type
- nall: Markup::find() strips spaces from values in comparisons
- higan: updated game manifest loading/saving code for all cores
- GBA: flash memory ID is internally selected based on the
manufacturer and memory size
- SFC: ST018 (ARM6) frequency can be modified via game manifest now
- WS: EEPROM::name removed (not useful)
- icarus, genius: battery→volatile updates
I did my best to look over the diff between r13 and r14, but it's 84KiB
excluding the game database changes. It's just too much for me. I'd
greatly appreciate if someone could look over it and check for any
errors in this update. But more than likely, I suppose we'll iron out
any issues by determining which games fail to load.
Right now, I know the Super Game Boy support doesn't seem to work. But
all non-SFC cores should work fully, and all normal + NEC DSP SFC games
should work as well. Unsure about the rest.
Also, I'm planning to change the Game Boy “MBC1M” mapper to “MBC1#A” to
indicate it's an alternate wiring configuration of the stock MBC1, and
not a new mapper type.

Update to v106r04 release.
byuu says:
Changelog:
- nall: `Markup::Node::operator[]` now uses `find()` instead of `lookup()`
behind the scenes
- Super Famicom: RAM memory ordering is now independent of ROM memory
ordering
- Super Famicom: added 19 new generic board definitions
- icarus: improved Super Famicom heuristics generation
Not putting it in the changelog, but the SPC7110 RAM now has write
protection disabled again.
99% of games should now be playable with heuristics. The exceptions
should be:
- 4MB LoROM games with SRAM (Ys 3, FE: Thracia 776)
- 2MB DSP LoROM games
- BS-X Town
- BS-X slotted games
- SA1 BSX slotted games
- SPC7110 games without the RTC (Momotarou Dentetsu Happy, Super Power
League 4)
- SPC7110 7MB fan translation (wasn't supported earlier either)
- ExLoROM games (wasn't supported earlier either)
- Sufami Turbo
- Campus Challenge '92 and Powerfest '94
- ST010 is going to run at 15MHz instead of 11MHz
- MSU1 (needs to be supported in higan, not icarus)
I'll add support for most of these before the release of v107.

Update to v106r2 release.
byuu says:
Changelog:
- Super Famicom: added support for loading manifests without embedded
mapping information¹
- genius: initial commit
- various Makefile cleanups
¹: so the idea here is to try and aim for a stable manifest format,
and to allow direct transposition of icarus/genius database entries into
manifest files. The exact mechanics of how this is going to work is
currently in flux, but we'll get there.
For right now, `Super Famicom.sys` gains `boards.bml`, which is the raw
database from my board-editor tool, and higan itself tries to load
`boards.bml`, match an entry to game/board from the game's `manifest.bml`
file, and then transform it into the format currently used by higan. It
does this only when the game's `manifest.bml` file lacks a board node.
When such a board node exists, it works as previous versions of higan
did.
The only incompatible change right now is information/title is now
located at game/label. I may transition window title display to just use
the filenames instead.
Longer term, some thought is going to need to go into the format of the
`boards.bml` database itself, and at which point in the process I should
be transforming things.
Give it time, we'll refine this into something nicer.

- handhelds lack soft reset obviously
- the PC Engine also lacks a physical reset button
- the Master System's reset button acts like a gamepad button, so
can't show up in the menu
- Mega Drive: power cycle wasn't initializing CPU (M68K) or APU (Z80)

- Super Famicom: removed `*::init()` functions, as they were never used
- Super Famicom: removed all but two `*::load()` functions, as they
were not used
- higan: added option to auto-save backup RAM every five seconds
(enabled by default)
- this is in case the emulator crashes, or there's a power outage;
turn it off under advanced settings if you want
- libco: updated license from public domain to ISC, for consistency
with nall, ruby, hiro
- nall: Linux compiler defaults to g++; override with g++-version if
g++ is <= 4.8
- FreeBSD compiler default is going to remain g++49 until my dev
box OS ships with g++ >= 4.9
Errata: I have weird RAM initialization constants, thanks to hex_usr

Update to v104r15 release.
byuu says:
Changelog:
- processor/huc6280,mos6502,wdc65816: replaced abbreviated opcode
names with descriptive names
- nall: replaced `PLATFORM_MACOSX` define with `PLATFORM_MACOS`
- icarus: added `Icarus::missing() -> string_vector` to list missing
appended firmware files by name
- ruby, hiro: fix macosx→macos references
The processor instruction renaming was really about consistency with the
other processor cores. I may still need to do this for one or two more
processors.
The icarus change should allow a future release of the icarus
application to import games with external SNES coprocessor firmware once
again. It will also allow this to be possible when used in library mode.

Update to v104r13 release.
byuu says:
Changelog:
- nall/GNUmakefile: build=release changed to -O2, build=optimize is
now -O3
- hiro: added Monitor::dpi(uint index) → Position [returns logical
DPI for x, y]
- Position is a bad name, but dpi(monitor).(x,y)() make more sense
than .(width,height)()
- hiro: Position, Size, Geometry, Font changed from using signed int
to float
- hiro: Alignment changed from using double to float
- hiro: added skeleton (unused) Application::scale(), setScale()
functions
Errata:
- hiro/cocoa's Monitor::dpi() is untested. Probably will cause issues
with macOS' automatic scaling.
- hiro/gtk lacks a way to get both per-monitor and per-axis (x,y) DPI
scaling
- hiro/qt lacks a way to get per-monitor DPI scaling (Qt 5.x has this,
but I still use Qt 4.x)
- and just to get global DPI, hiro/qt's DPI retrieval has to use
undocumented functions ... fun
The goal with this WIP was basically to prepare hiro for potential
automatic scaling. It'll be extremely difficult, but I'm convinced that
it must be possible if macOS can do it.
By moving from signed integers to floats for coordinates, we can now
scale and unscale without losing precision. That of course isn't the
hard part, though. The hard part is where and how to do the scaling. In
the ideal application, hiro/core and hiro/extension will handle 100% of
this, and the per-platform hiro/(cocoa,gtk,qt,windows) will not be aware
of what's going on, but ... to even make that possible, things will need
to change in every per-platform core, eg the per-platform code will have
to call a core function to change geometry, which will know about the
scaling and unscale the values back down again.
Gonna be a lot of work, but ... it's a start.

- sfc/ppu/background: use hires/interlace/mosaic-adjusted X/Y
coordinates for offset-per-tile mode
- sfc/ppu/background: hires mosaic seems to advance pixel counter on
subscreen pixels
- tomoko: added “Help→Credits” menu option (currently the page does

- tomoko: reduced volume slider from {0% - 500%} to {0% - 200%}.
Distortion is too intense above 200%.

Prince of Persia for the SNES
- nall/run/invoke: use program path for working directory
- allows you to choose “Library→Import ROMs” from a different

I don't know how to assign credit for the mosaic stuff. It's been a
work-in-progress with me, Cydrak, and hex_usr.
The current design should be correct, but very unpleasant. The code
desperately needs to be refactored, but my recent attempt at doing so
ended in spectacular failure.

- gb: added rumble input¹
- gb/mbc5: added rumble support²
- gb/mbc6: added skeleton driver, but it doesn't boot Net de Get

- icarus: enhance Game Boy heuristics³
- nall: fix three missing return statements [Jonas Quinn]
- ruby: hopefully fixed all compilation errors reported by Screwtape
et al⁴
¹: because there's no concept of a controller for cartridge inputs,
I'm attaching to the base platform for now. An idea I had was to make
separate ports for each cartridge type ... but this would duplicate the
rumble input between MBC5 and MBC7. And would also be less discoverable.
But it would be more clean in that users wouldn't think the Game Boy
hardware had this functionality. I'll think about it.
²: it probably won't work yet. Rumble isn't documented anywhere, but
I dug through an emulator named GEST and discovered that it seems to use
bit 3 of the RAM bank select to be rumble. I don't know if it sets the
bit for rumbling, then clears when finished, or if it sets it and then
after a few milliseconds it stops rumbling. I couldn't test on my
FreeBSD box because SDL 1.2 doesn't support rumble, udev doesn't exist
on FreeBSD, and nobody has ever posted any working code for how to use
evdev (or whatever it's called) on FreeBSD.
³: I'm still thinking about specifying the MBC7 RAM as EEPROM, since
it's not really static RAM.
⁴: if possible, please test all drivers if you can. I want to ensure
they're all working. Especially let me know if the following work:
macOS: input.carbon Linux: audio.pulseaudiosimple, audio.ao (libao)
If I can confirm these are working, I'm going to then remove them from
being included with stock higan builds.
I'm also considering dropping SDL video on Linux/BSD. XShm is much
faster and supports blurring. I may also drop SDL input on Linux, since
udev works better. That will free a dependency on SDL 1.2 for building
higan. FreeBSD is still going to need it for joypad support, however.

Update to v103r13 release.
byuu says:
Changelog:
- gb/interface: fix Game Boy Color extension to be "gbc" and not "gb"
[hex\_usr]
- ms/interface: move Master System hardware controls below controller
ports
- sfc/ppu: improve latching behavior of BGnHOFS registers (not
hardware verified) [AWJ]
- tomoko/input: rework port/device mapping to support non-sequential
ports and devices¹
- todo: should add move() to inputDevice.mappings.append and
inputPort.devices.append
- note: there's a weird GCC 4.9 bug with brace initialization of
InputEmulator; have to assign each field separately
- tomoko: all windows sans the main presentation window can be
dismissed with the escape key
- icarus: the single file selection dialog ("Load ROM Image...") can
be dismissed with the escape key
- tomoko: do not pause emulation when FocusLoss/Pause is set during
exclusive fullscreen mode
- hiro/(windows,gtk,qt): implemented Window::setDismissable() function
(missing from cocoa port, sorry)
- nall/string: fixed printing of largest possible negative numbers (eg
`INT_MIN`) [Sintendo]
- only took eight months! :D
¹: When I tried to move the Master System hardware port below the
controller ports, I ran into a world of pain.
The input settings list expects every item in the
`InputEmulator<InputPort<InputDevice<InputMapping>>>>` arrays to be
populated with valid results. But these would be sparsely populated
based on the port and device IDs from inside higan. And that is done so
that the Interface::inputPoll can have O(1) lookup of ports and devices.
This worked because all the port and device IDs were sequential (they
left no gaps in the maps upon creating the lists.)
Unfortunately by changing the expectation of port ID to how it appears
in the list, inputs would not poll correctly. By leaving them alone and
just moving Hardware to the third position, the Game Gear would be
missing port IDs of 0 and 1 (the controller ports of the Master System).
Even by trying to make separate MasterSystemHardware and
GameGearHardware ports, things still fractured when the devices were no
longer contigious.
I got pretty sick of this and just decided to give up on O(1)
port/device lookup, and moved to O(n) lookup. It only knocked the
framerate down by maybe one frame per second, enough to be in the margin
of error. Inputs aren't polled *that* often for loops that usually
terminate after 1-2 cycles to be too detrimental to performance.
So the new input system now allows non-sequential port and device IDs.
Remember that I killed input IDs a while back. There's never any reason
for those to need IDs ... it was easier to just order the inputs in the
order you want to see them in the user interface. So the input lookup is
still O(1). Only now, everything's safer and I return a
maybe<InputMapping&>, and won't crash out the program trying to use a
mapping that isn't found for some reason.
Errata: the escape key isn't working on the browser/message dialogs on
Windows, because of course nothing can ever just be easy and work for
me. If anyone else wouldn't mind looking into that, I'd greatly
appreciate it.
Having the `WM_KEYDOWN` test inside the main `Application_sharedProc`, it
seems to not respond to the escape key on modal dialogs. If I put the
`WM_KEYDOWN` test in the main window proc, then it doesn't seem to get
called for `VK_ESCAPE` at all, and doesn't get called period for modal
windows. So I'm at a loss and it's past 4AM here >_>

Update to v103r01 release.
byuu says:
Changelog:
- nall/dsp: improve one pole coefficient calculations [Fatbag]
- higan/audio: reworked filters to support selection of either one
pole (first-order) or biquad (second-order) filters
- note: the design is not stable yet; so forks should not put too
much effort into synchronizing with this change yet
- fc: added first-order filters as per NESdev wiki (90hz lowpass +
440hz lowpass + 14khz highpass)
- fc: created separate NTSC-J and NTSC-U regions
- NESdev wiki says the Japanese Famicom uses a separate audio
filtering strategy, but details are fuzzy
- there's also cartridge audio output being disabled on NES units;
and differences with controllers
- this stuff will be supported in the future, just adding the
support for it now
- gba: corrected serious bugs in PSG wave channel emulation [Cydrak]
- note that if there are still bugs here, it's my fault
- md/psg,ym2612: added first-order low-pass 2840hz filter to match
VA3-VA6 Mega Drives
- md/psg: lowered volume relative to the YM2612
- using 0x1400; multiple people agreed it was the closest to the
hardware recordings against a VA6
- ms,md/psg: don't serialize the volume levels array
- md/vdp: Hblank bit acts the same during Vblank as outside of it (it
isn't always set during Vblank)
- md/vdp: return isPAL in bit 0 of control port reads
- tomoko: change command-line option separator from : to |
- [Editor's note: This change was present in the public v103,
but it's in this changelog because it was made after the v103 WIP]
- higan/all: change the 20hz high-pass filters from second-order
three-pass to first-order one-pass
- these filters are meant to remove DC bias, but I honestly can't
hear a difference with or without them
- so there's really no sense wasting CPU power with an extremely
powerful filter here
Things I did not do:
- change icarus install rule
- work on 8-bit Mega Drive SRAM
- work on Famicom or Mega Drive region detection heuristics in icarus
My long-term dream plan is to devise a special user-configurable
filtering system where you can set relative volumes and create your own
list of filters (any number of them in any order at any frequency), that
way people can make the systems sound however they want.
Right now, the sanest place to put this information is inside the
$system.sys/manifest.bml files. But that's not very user friendly, and
upgrading to new versions will lose these changes if you don't copy them
over manually. Of course, cluttering the GUI with a fancy filter editor
is probably supreme overkill for 99% of users, so maybe that's fine.

- GBA: substantially improved audio mixing
- fixed bug with FIFO 50%/100% volume setting
- now properly using SOUNDBIAS amplitude to control output
frequencies
- reduced quantization noise
- corrected relative volumes between PSG and FIFO channels
- both PSG and FIFO values cached based on amplitude; resulting in
cleaner PCM samples
- treating PSG volume=3 as 200% volume instead of 0% volume now
(unverified: to match mGBA)
- GBA: properly initialize ALL CPU state; including the vital
prefetch.wait=1 (fixes Classic NES series games)
- GBA: added video rotation with automatic key translation support
- PCE: reduced output resolution scalar from 285x242 to 285x240
- the extra two scanlines won't be visible on most TVs; and they
make all other cores look worse
- this is because all other cores output at 240p or less; so they
were all receiving black bars in windowed mode
- tomoko: added "Rotate Display" hotkey setting
- tomoko: changed hotkey multi-key logic to OR instead of AND
- left support for flipping it back inside the core; for those so
inclined; by uncommenting one line in input.hpp
- tomoko: when choosing Settings→Configuration, it will
automatically select the currently loaded system
- for instance, if you're playing a Game Gear game, it'll take you
to the Game Gear input settings
- if no games are loaded, it will take you to the hotkeys panel
instead
- WS(C): merged "Hardware-Vertical", "Hardware-Horizontal" controls
into combined "Hardware"
- WS(C): converted rotation support from being inside the core to
using Emulator::Video
- this lets WS(C) video content scale larger now that it's not
bounded by a 224x224 square box
- WS(C): added automatic key rotation support
- WS(C): removed emulator "Rotate" key (use the general hotkey
instead; I recommend F8 for this)
- nall: added serializer support for nall::Boolean (boolean) types
- although I will probably prefer the usage of uint1 in most cases

Now would be the time to start looking for major regressions with the
new GBA PPU renderer, I suppose ...
¹: this doesn't matter for the master thread (SNES CPU), but is
important for slave threads (SNES SA1). If you try to save a state and
the SA1 is inside of a WAI instruction, it will get stuck there forever.
This was causing attempts to create a save state in Super Bomberman
- Panic Bomber W to deadlock the emulator and crash it. This is now
finally fixed.
Note that I still need to implement similar functionality into the Mega
Drive 68K and Z80 cores. They still have the possibility of deadlocking.
The SNES implementation was more a dry-run test for this new
functionality. This possible crashing bug in the Mega Drive core is the
major blocking bug for a new official release.
²: many, many thanks to hex\_usr for coming up with a really nice
design. I mostly implemented it the exact same way, but with a few tiny
differences that don't really matter (display " and ", " or " instead of
" & ", " | " in the input settings windows; append → bind;
assignmentName changed to displayName.)
The actual functionality is identical to the old higan v094 and earlier
builds. Emulated digital inputs let you combine multiple possible keys
to trigger the buttons. This is OR logic, so you can map to eg
keyboard.up OR gamepad.up for instance. Emulated analog inputs always
sum together. Emulated rumble outputs will cause all mapped devices to
rumble, which is probably not at all useful but whatever. Hotkeys use
AND logic, so you have to press every key mapped to trigger them. Useful
for eg Ctrl+F to trigger fullscreen.
Obviously, there are cases where OR logic would be nice for hotkeys,
too. Eg if you want both F11 and your gamepad's guide button to trigger
the fullscreen toggle. Unfortunately, this isn't supported, and likely
won't ever be in tomoko. Something I might consider is a throw switch in
the configuration file to swap between AND or OR logic for hotkeys, but
I'm not going to allow construction of mappings like "(Keyboard.Ctrl and
Keyboard.F) or Gamepad.Guide", as that's just too complicated to code,
and too complicated to make a nice GUI to set up the mappings for.

Changelog:
- nall: `#undef OUT` on Windows platform
- GBA: add missing CPU prefetch state to serialization (this was
breaking serialization in games using ROM prefetch)
- GBA: reset all PPU data in the power() function (some things were
missing before, causing issues on reset)
- GBA: restored horizontal mosaic emulation to the new pixel-based
renderer
- GBA: fixed tilemap background horizontal flipping (Legend of Spyro -

- left stub for old dmaCounter so that I can do some traces to
ensure the new code's 100% identical
GBA save states would have been broken since whenever I emulated ROM
prefetch. I guess not many people are using the GBA core ...

Update to v102r15 release.
byuu says:
Changelog:
- nall: added DSP::IIR::OnePole (which is a first-order IIR filter)
- FC/APU: removed strong highpass, weak hipass filters (and the
dummied out lowpass filter)
- MS,GG,MD/PSG: removed lowpass filter
- MS,GG,MD/PSG: audio was not being centered properly; removed
centering for now
- MD/YM2612: fixed clipping of accumulator from 18 signed bits to 14
signed bits (-0x2000 to +0x1fff) [Cydrak]
- MD/YM2612: removed lowpass filter
- PCE/PSG: audio was not being centered properly; removed centering
for now
First thing is that I've removed all of the ad-hoc audio filtering.
Emulator::Stream intrinsically provides a three-pass, second-order
biquad IIR butterworth lowpass filter that clips frequencies above 20KHz
with very good attenuation (as good as IIR gets, anyway.)
It doesn't really make sense to have the various cores running
additional lowpass filters. If we want to filter frequencies below
20KHz, then I can adapt Emulator::Audio::createStream() to take a cutoff
frequency value, and we can do it all at once, with much better quality.
Right now, I don't know what frequencies are best to cut off the various
other audio cores, so they're just gone for now.
As for the highpass filters for the Famicom core, well ... you don't get
aliasing from resampling low frequencies. And generally speaking, too
low a frequency will be inaudible anyway. All these were doing was
killing possible bass (if they were too strong.) We can add them again,
but only if someone can convert Ryphecha's ad-hoc magic integers into a
frequency cutoff. In which case, I'll use my biquad IIR filter to do it
even better. On this note, it may prove useful to do this for the MD PSG
as well, to try and head off unnecessary clamping when mixing with the
YM2612.
Finally, there was the audio centering issue that affected the
MS,GG,MD,PCE,SG cores. It was flooring the "silent" audio level, which
was resulting in extremely heavy distortion if you tried listening to
higan and, say, audacious at the same time. Without the botched
centering, this distortion is completely gone now.
However, without any centering, we've halved the potential volume range.
This means the audio slider in higan's audio settings panel will start
clamping twice as quickly. So ultimately, we need to figure out how to
fix the centering. This isn't as simple as just subtracting less. We
will probably have to center every individual audio channel before
summing them to do this properly.
Results:
On the Mega Drive, Altered Beast sounds quite a bit better, a lot less
distortion now. But it's still not perfect, especially sound effects.
Further, Bare Knuckle / Streets of Rage still has really bad sound
effects. It looks like I broke something in Cydrak's code when trying to
adapt it to my style =(

Update to v102r12 release.
byuu says:
Changelog:
- MD/PSG: fixed 68K bus Z80 status read address location
- MS, GG, MD/PSG: channels post-decrement their counters, not
pre-decrement [Cydrak]¹
- MD/VDP: cache screen width registers once per scanline; screen
height registers once per frame
- MD/VDP: support 256-width display mode (used in Shining Force, etc)
- MD/YM2612: implemented timers²
- MD/YM2612: implemented 8-bit PCM DAC²
- 68000: TRAP instruction should index the vector location by 32 (eg
by 128 bytes), fixes Shining Force
- nall: updated hex(), octal(), binary() functions to take uintmax
instead of template<typename T> parameter³
¹: this one makes an incredible difference. Sie noticed that lots of
games set a period of 0, which would end up being a really long period
with pre-decrement. By fixing this, noise shows up in many more games,
and sounds way better in games even where it did before. You can hear
extra sound on Lunar - Sanposuru Gakuen's title screen, the noise in
Sonic The Hedgehog (Mega Drive) sounds better, etc.
²: this also really helps sound. The timers allow PSG music to play
back at the correct speed instead of playing back way too quickly. And
the PCM DAC lets you hear a lot of drum effects, as well as the
"Sega!!" sound at the start of Sonic the Hedgehog, and the infamous,
"Rise from your grave!" line from Altered Beast.
Still, most music on the Mega Drive comes from the FM channels, so
there's still not a whole lot to listen to.
I didn't implement Cydrak's $02c test register just yet. Sie wasn't 100%
certain on how the extended DAC bit worked, so I'd like to play it a
little conservative and get sound working, then I'll go back and add a
toggle or something to enable undocumented registers, that way we can
use that to detect any potential problems they might be causing.
³: unfortunately we lose support for using hex() on nall/arithmetic
types. If I have a const Pair& version of the function, then the
compiler gets confused on whether Natural<32> should use uintmax or
const Pair&, because compilers are stupid, and you can't have explicit
arguments in overloaded functions. So even though either function would
work, it just decides to error out instead >_>
This is actually really annoying, because I want hex() to be useful for
printing out nall/crypto keys and hashes directly.
But ... this change had to be made. Negative signed integers would crash
programs, and that was taking out my 68000 disassembler.

Update to v102r06 release.
byuu says:
Changelog:
- added higan/emulator/platform.hpp (moved out Emulator::Platform from
emulator/interface.hpp)
- moved gmake build paramter to nall/GNUmakefile; both higan and
icarus use it now
- added build=profile mode
- MD: added the region select I/O register
- MD: started to add region selection support internally (still no
external select or PAL support)
- PCE: added cycle stealing when reading/writing to the VDC or VCE;
and when using ST# instructions
- PCE: cleaned up PSG to match the behavior of Mednafen (doesn't
improve sound at all ;_;)
- note: need to remove loadWaveSample, loadWavePeriod
- HuC6280: ADC/SBC decimal mode consumes an extra cycle; does not set
V flag
- HuC6280: block transfer instructions were taking one cycle too many
- icarus: added code to strip out PC Engine ROM headers
- hiro: added options support to BrowserDialog
The last one sure ended in failure. The plan was to put a region
dropdown directly onto hiro::BrowserDialog, and I had all the code for
it working. But I forgot one important detail: the system loads
cartridges AFTER powering on, so even though I could technically change
the system region post-boot, I'd rather not do so.
So that means we have to know what region we want before we even select
a game. Shit.

Update to v101r25 release.
byuu says: Changelog: - SMS: emulated VDP mode 4 graphical output (background, sprites) - added $(windres) to icarus as well I'm sure the VDP emulation is still really, really buggy, but essentially I handle: - mode 4 rendering - background scrolling - background hscroll lock - background vscroll lock - background nametable relocation - sprite nametable relocation - sprite tiledata relocation - sprite 192-line y=0xd0 edge case (end sprite rendering) - sprite 8-pixel x-coordinate displacement - sprite extended size (height only in mode 4) - sprite overflow - sprite collision - left column masking - display disable - backdrop color - 192, 224, 240 height I do not support: - mode 2 rendering - sprite zoom - disallowing 240 height in NTSC mode - PAL mode - probably lots more |

Update to v101r24 release.
byuu says:
Changelog:
- SMS: extended bus mapping of in/out ports: now decoding them fully
inside ms/bus
- SMS: moved Z80 disassembly code from processor/z80 to ms/cpu
(cosmetic)
- SMS: hooked up non-functional silent PSG sample generation, so I can
cap the framerate at 60fps
- SMS: hooked up the VDP main loop: 684 clocks/scanline, 262
scanlines/frame (no PAL support yet)
- SMS: emulated the VDP Vcounter and Hcounter polling ... hopefully
it's right, as it's very bizarre
- SMS: emulated VDP in/out ports (data read, data write, status read,
control write, register write)
- SMS: decoding and caching all VDP register flags (variable names
will probably change)
- nall: \#undef IN on Windows port (prevent compilation warning on
processor/z80)
Watching Sonic the Hedgehog, I can definitely see some VDP register
writes going through, which is a good sign.
Probably the big thing that's needed before I can get enough into the
VDP to start showing graphics is interrupt support. And interrupts are
never fun to figure out :/
What really sucks on this front is I'm flying blind on the Z80 CPU core.
Without a working VDP, I can't run any Z80 test ROMs to look for CPU
bugs. And the CPU is certainly too buggy still to run said test ROM
anyway. I can't find any SMS emulators with trace logging from reset.
Such logs vastly accelerate tracking down CPU logic bugs, so without
them, it's going to take a lot longer.

Update to v101r19 release.
byuu says:
Changelog:
- added \~130 new PAL games to icarus (courtesy of Smarthuman
and aquaman)
- added all three Korean-localized games to icarus
- sfc: removed SuperDisc emulation (it was going nowhere)
- sfc: fixed MSU1 regression where the play/repeat flags were not
being cleared on track select
- nall: cryptography support added; will be used to sign future
databases (validation will always be optional)
- minor shims to fix compilation issues due to nall changes
The real magic is that we now have 25-30% of the PAL SNES library in
icarus!
Signing will be tricky. Obviously if I put the public key inside the
higan archive, then all anyone has to do is change that public key for
their own releases. And if you download from my site (which is now over
HTTPS), then you don't need the signing to verify integrity. I may just
put the public key on my site on my site and leave it at that, we'll
see.

Update to v101r18 release.
byuu says: Changelog: - added 30 new PAL games to icarus (courtesy of Mikerochip) - new version of libco no longer requires mprotect nor W|X permissions - nall: default C compiler to -std=c11 instead of -std=c99 - nall: use `-fno-strict-aliasing` during compilation - updated nall/certificates (hopefully for the last time) - updated nall/http to newer coding conventions - nall: improve handling of range() function I didn't really work on higan at all, this is mostly just a release because lots of other things have changed. The most interesting is `-fno-strict-aliasing` ... basically, it joins `-fwrapv` as being "stop the GCC developers from doing *really* evil shit that could lead to security vulnerabilities or instabilities." For the most part, it's a ~2% speed penalty for higan. Except for the Sega Genesis, where it's a ~10% speedup. I have no idea how that's possible, but clearly something's going very wrong with strict aliasing on the Genesis core. So ... it is what it is. If you need the performance for the non-Genesis cores, you can turn it off in your builds. But I'm getting quite sick of C++'s "surprises" and clever compiler developers, so I'm keeping it on in all of my software going forward. |

Update to v101r14 release.
byuu says:
Changelog:
- rewrote the Z80 core to properly handle 0xDD (IX0 and 0xFD (IY)
prefixes
- added Processor::Z80::Bus as a new type of abstraction
- all of the instructions implemented have their proper T-cycle counts
now
- added nall/certificates for my public keys
The goal of `Processor::Z80::Bus` is to simulate the opcode fetches being
2-read + 2-wait states; operand+regular reads/writes being 3-read. For
now, this puts the cycle counts inside the CPU core. At the moment, I
can't think of any CPU core where this wouldn't be appropriate. But it's
certainly possible that such a case exists. So this may not be the
perfect solution.
The reason for having it be a subclass of Processor::Z80 instead of
virtual functions for the MasterSystem::CPU core to define is due to
naming conflicts. I wanted the core to say `in(addr)` and have it take
the four clocks. But I also wanted a version of the function that didn't
consume time when called. One way to do that would be for the core to
call `Z80::in(addr)`, which then calls the regular `in(addr)` that goes to
`MasterSystem::CPU::in(addr)`. But I don't want to put the `Z80::`
prefix on all of the opcodes. Very easy to forget it, and then end up not
consuming any time. Another is to use uglier names in the
`MasterSystem::CPU` core, like `read_`, `write_`, `in_`, `out_`, etc. But,
yuck.
So ... yeah, this is an experiment. We'll see how it goes.
