For this WIP, I added more TLCS900H instructions. All of the
ADC,ADD,SBB/SBC,SUB,AND,OR,XOR.CP,PUSH,POP instructions are in.
Still an incredible amount of work left to do on this core ... it has all kinds
of novel instructions that aren't on any other processors.
Still no disassembler support yet, so I can't even test what I'm doing. Fun!
byuu says:
I started working on the Toshiba TLCS900H CPU core today.
It's basically, "what if we took the Z80, added in 32-bit support, added
in SPARC register windows, added a ton of additional addressing modes,
added control registers, and added a bunch of additional instructions?"
-- or in other words, it's basically hell for me.
It took several hours just to wrap my head around the way the opcode
decoder needed to function, but I think I have a decent strategy for
implementing it now.
I should have all of the first-byte register/memory address decoding in
place, although I'm sure there's lots of bugs. I don't have anything in
the way of a disassembler yet.
byuu says:
The biggest change was improving WonderSwan emulation. With help from
trap15, I tracked down a bug where I was checking the wrong bit for
reverse DMA transfers. Then I also emulated VTOTAL to support variable
refresh rate. Then I improved HyperVoice emulation which should be
unsigned samples in three of four modes. That got Fire Lancer running
great. I also rewrote the disassembler. The old one disassembled many
instructions completely wrong, and deviated too much from any known x86
syntax. I also emulated some of the quirks of the V30 (two-byte POP into
registers fails, SALC is just XLAT mirrored, etc) which probably don't
matter unless someone tries to run code to verify it's a NEC CPU and not
an Intel CPU, but hey, why not?
I also put more work into the MSX skeleton, but it's still just a
skeleton with no real emulation yet.
byuu says:
Changelog:
- nall: converted range, iterator, vector to 64-bit
- added (very poor) ColecoVision emulation (including Coleco Adam
expansion)
- added MSX skeleton
- added Neo Geo Pocket skeleton
- moved audio,video,resource folders into emulator folder
- SFC heuristics: BS-X Town cart is "ZBSJ" [hex_usr]
The nall change is for future work on things like BPA: I need to be able
to handle files larger than 4GB. It is extremely possible that there are
still some truncations to 32-bit lurking around, and even more
disastrously, possibly some -1s lurking that won't sign-extend to
`(uint64_t)0-1`. There's a lot more classes left to do: `string`,
`array_view`, `array_span`, etc.
byuu says:
Changelog:
- added all pre-requisite to make install rule (note: only for higan,
icarus so far)
- added SG-1000 emulation
- added SC-3000 emulation (no keyboard support yet)
- added MS graphics mode 1 emulation (SC-1000)
- added MS graphics mode 2 emulation (F-16 Fighter)
- improve Audio::process() to prevent a possible hang
- higan: repeat monaural audio to both left+right speakers
- icarus: add heuristics for importing MSX games (not emulated in
higan yet in this WIP)
- added DC bias removal filter [jsd1982]
- improved Audio::Stream::reset() [jsd1982]
I was under the impression that the 20hz highpass filter would have
removed DC bias ... if not, then I don't know why I added that filter to
all of the emulation cores that have it. In any case, if anyone is up
for helping me out ... if we could analyze the output with and without
the DC bias filter to see if it's actually helping, then I'll enable it
if it is. To enable it, edit
higan/audio/stream.cpp::addDCRemovalFilter() and remove the return
statement at the top of the function.
byuu says:
Changelog:
- moved to GCC 8.2 and C++17
- fixed compilation under FreeBSD 12.0
- don't read beyond the file size in
SuperFamicom::Cartridge::loadMemory
- add missing I/O cycle HuC6280::instructionImmediate
- serialize Mega Drive's Game Genie state
- serialize SPC7110::Thread information
- enable 30-bit color depth support under the GLX/OpenGL 2.0 driver
(doesn't work with OpenGL 3.2 yet)
The 30-bit color depth option isn't super useful, but why not? I need to
update ruby to detect that the display is actually capable of it before
exposing an option that can result in the driver failing to initialize,
however.
byuu says:
This synchronizes bsnes/higan with many recent internal nall changes.
This will be the last WIP until I am situated in Japan. Apologies for the
bugfixes that didn't get applied yet, I ran out of time.
byuu says:
Changelog:
- gb/mbc7: rewrote the 93LCx6 EEPROM emulation
- sfc/slot/bsmemory: rewrote the flash emulation for Satellaview
cartridges
As of this release, flash-based BS Memory cartridges will be writable.
So without the bsnes patch to disable write limits, some games will lock
out after a few plays.
byuu says:
Changelog:
- sfc/cx4: added missing instructions [info from Overload]
- sfc/cx4: added instruction cache emulation [info from ikari]
- sfc/sa1: don't let CPU access SA1-only I/O registers, and vice versa
- sfc/sa1: fixed IRQs that were broken from the recent WIP
- sfc/sa1: significantly improved bus conflict emulation
- all tests match hardware now, other than HDMA ROM↔ROM, which
is 0.5 - 0.8% too fast
- sfc/cpu: fixed a bug with DMA→CPU alignment timing
- sfc/cpu: removed the DMA pipe; performs writes on the same cycles as
reads [info from nocash]
- sfc/memory: fix a crashing bug due to not clearing Memory size field
[hex_usr]
- bsnes/gb: use .rtc for real-time clock file extensions on the Game
Boy [hex_usr]
- ruby/cgl: compilation fix [Sintendo]
Now let's see if I can accept being off by ~0.65% on one of twelve SA1
timing tests for the time being and prioritize much more important
things or not.
byuu says:
This release adds ikari's Cx4 notes to bsnes. It fixes the MMX2 intro's
boss fight sequence to be frame perfect to real hardware. It's also very
slightly faster than before.
I've also added an option to toggle the CPU↔coprocessor cycle
synchronization to the emulation settings panel, so you don't have to
recompile to get the more accurate SA1 timings. I'm most likely going to
default this to disabled in bsnes, and *maybe* enabled in higan out of
the box.
StaticRAM (wasn't used) and MappedRAM are gone from the Super Famicom
core. Instead, there's now ReadableMemory, WritableMemory, and
ProtectedMemory (WritableMemory with a toggle for write protection.)
Cartridge::loadMap now takes a template Memory object, which bypasses an
extra virtual function call on memory accesses, but it doesn't really
impact speed much. Whatever.
byuu says:
I added (imperfect) memory conflict timing to the SA1.
Before:
- WRAM↔↔ROM ran 7% too fast
- ROM↔↔ROM ran 100% too fast
- WRAM↔↔IRAM ran 7% too fast
- ROM↔↔IRAM ran 7% too fast
- IRAM↔↔IRAM ran 287% too fast
- BWRAM↔↔BWRAM ran 100% too fast
- HDMA ROM↔↔ROM ran 15% too fast
- HDMA WRAM↔↔ROM ran 15% too fast
- DMA ROM↔↔ROM ran 100% too fast
After:
- ROM↔↔ROM runs 14% too fast
- HDMA WRAM↔↔ROM runs 7% too fast
- DMA ROM↔↔ROM runs 4% too fast
If you enable this with the fast PPU + DSP, your framerate in SA1 games
will drop by 51%. And even if you disable it, you'll still lose 9% speed
in SA1 games, and 2% speed in non-SA1 games, because of changes needed
to make this support possible.
By default, I'm leaving this off. Compile with `-DACCURATE_SA1` (or
uncomment the line in sfc/sfc.hpp) if you want to try it out.
This'll almost certainly cause some SA1 regressions, so I guess we'll
tackle those as they arise.
byuu says:
Changelog:
- fixed bug in Emulator::Game::Memory::operator bool()
- nall: renamed view<string> back to `string_view`
- nall:: implemented `array_view`
- Game Boy: split cartridge-specific input mappings (rumble,
accelerometer) to their own separate ports
- Game Boy: fixed MBC7 accelerometer x-axis
- icarus: Game Boy, Super Famicom, Mega Drive cores output internal
header game titles to heuristics manifests
- higan, icarus, hiro/gtk: improve viewport geometry configuration;
fixed higan crashing bug with XShm driver
- higan: connect Video::poll(),update() functionality
- hiro, ruby: several compilation / bugfixes, should get the macOS
port compiling again, hopefully [Sintendo]
- ruby/video/xshm: fix crashing bug on window resize
- a bit hacky; it's throwing BadAccess Xlib warnings, but they're
not fatal, so I am catching and ignoring them
- bsnes: removed Application::Windows::onModalChange hook that's no
longer needed [Screwtape]
byuu says:
The main thing I worked on today was emulating the MBC7 EEPROM.
And... I have many things to say about that, but not here, and not now...
The missing EEPROM support is why the accelerometer was broken. Although
it's not evidently clear that I'm emulating the actual values
incorrectly. I'll think about it and get it fixed, though.
bsnes went from ~308fps to ~328fps, and I don't even know why. Probably
something somewhere in the 140KB of changes to other things made in this
WIP.
byuu says:
This release fixes the XAudio 2.1 and WASAPI drivers on Windows, and
extends XAudio to support device selection (eg headphones, speakers,
monitor, etc.) It also adds DRC to XAudio, however it's not currently
working.
The code is courtesy of Talarubi, I just botched it somewhere upon
porting it to the newer version of ruby.
byuu says:
I've added tool tips to hiro for Windows, GTK, and Qt. I'm unsure how to
add them for Cocoa. I wasted am embarrassing ~14 hours implementing tool
tips from scratch on Windows, because the `TOOLTIPS_CLASS` widget just
absolutely refused to show up, no matter what I tried. As such, they're
not quite 100% native, but I would really appreciate any patch
submissions to help improve my implementation.
I added tool tips to all of the confusing settings in bsnes. And of
course, for those of you who don't like them, there's a configuration
file setting to turn them off globally.
I also improved Mega Drive handling of the Game Genie a bit, and
restructured the way the Settings class works in bsnes.
Starting now, I'm feature-freezing bsnes and higan. From this point
forward:
- polishing up and fixing bugs caused by the ruby/hiro changes
- adding DRC to XAudio2, and maybe exclusive mode to WGL
- correcting FEoEZ (English) to load and work again out of the box
Once that's done, a final beta of bsnes will go out, I'll fix any
reported bugs that I'm able to, and then v107 should be ready. This time
with higan being functional, but marked as v107 beta. v108 will restore
higan to production status again, alongside bsnes.
byuu says:
I fixed all outstanding bugs that I'm aware of, including all of the
errata I listed yesterday.
And now it's time for lots of regression testing.
After that, I need to add Talarubi's XAudio2 DRC code, and then get a
new public bsnes WIP out for final testing.
New errata: when setting an icon (nall::image) larger than a Canvas on
Windows, it's not centering the image, so you end up seeing the overscan
area in the state manager previews, and the bottom of the image gets cut
off. I also need to forcefully disable the Xlib screensaver disable
support. I think I'll remove the GUI option to bypass it as well, and
just force screensaver disable always on with Windows. I'll improve it
in the future to toggle the effect between emulator pauses.
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.
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.
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.
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.
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.
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.
byuu says:
I stand corrected, I managed to create and even larger diff than ever.
This one weighs in at 309KiB `>__>`
I'll have to create a changelog later, I'm too tired right now to go
through all of that.
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
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
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)
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.

- 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

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.
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.
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.

Changelog:
- nall/GNUmakefile: build=release changed to -O2, build=optimize is

- hiro: added Monitor::dpi(uint index) → Position [returns logical

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.

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.

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 >_>
