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.

longer needed [Screwtape]
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:
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.

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:
Once again, I wasn't able to complete a full WIP revision.
This WIP-WIP adds very sophisticated emulation of the Sega Genesis
Lock-On and Game Genie cartridges ... essentially, through recursion and
a linked list, higan supports an infinite nesting of cartridges.
Of course, on real hardware, after you stack more than three or four
cartridges, the power draw gets too high and things start glitching out
more and more as you keep stacking. I've heard that someone chained up
to ten Sonic & Knuckles cartridges before it finally became completely
unplayable.
And so of course, higan emulates this limitation as well ^-^. On the
fourth cartridge and beyond, it will become more and more likely that
address and/or data lines "glitch" out randomly, causing various
glitches. It's a completely silly easter egg that requires no speed
impact whatsoever beyond the impact of the new linked list cartridge
system.
I also designed the successor to Emulator::Interface::cap,get,set. Those
were holdovers from the older, since-removed ruby-style accessors.
In its place is the new Emulator::Interface::configuration,configure
API. There's the usual per-property access, and there's also access to
read and write all configurable options at once. In essence, this
enables introspection into core-specific features.
So far, you can control processor version#s, PPU VRAM size, video
settings, and hacks. As such, the .sys/manifest.bml files are no longer
necessary. Instead, it all goes into .sys/configuration.bml, which is
generated by the emulator if it's missing.
higan is going to take this even further and allow each option under
"Systems" to have its own editable configuration file. So if you wanted,
you could have a 1/1/1 SNES menu option, and a 2/1/3 SNES menu option.
Or a Model 1 Genesis option, and a Model 2 Genesis option. Or the
various Game Boy model revisions. Or an "SNES-Fast" and "SNES-Accurate"
option.
I've not fully settled on the syntax of the new configuration API. I
feel it might be useful to provide type information, but I really quite
passionately hate any<T> container objects. For now it's all
string-based, because strings can hold anything in nall.
I might also change the access rules. Right now it's like:
emulator→configure("video/blurEmulation", true); but it might be nicer
as "Video::Blur Emulation", or "Video.BlurEmulation", or something like
that.
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:
I failed to complete a WIP, have five of eight cores updated with some
major changes to Emulator::Interface. I'll just post a quick temporary
WIP in the off chance someone wants to look over the new interface and
comment on it.
Also implemented screen saver suppression into hiro/GTK.
I should also add ... a plan of mine is to develop target-bsnes into a
more generic user interface, with the general idea being that
target-higan is for multiple Emulator::Interface cores at the same time,
and target-bsnes is for just one Emulator::Interface core.
The idea being that if one were to compile target-bsnes with the GBA
core, it'd become bgba, for instance.
I don't plan on releasing single-core emulators like this, but ... I don't see any downsides to being more flexible.
byuu says:
Changelog:
- added `Emulator::Interface::connected(uint port) -> uint device;`
- higan, bsnes: updated emulators to use the new
Emulator::Interface::connected() function
- hiro: fixed Object::cast<T> finally
So, Emulator::Interface::connected() solves two annoying problems at the
same time.
First, on first run of the emulator when the settings file is blank, it
will retrieve the default "sane" device ID, which is usually a gamepad
for a controller port, or nothing for an expansion/extension port.
Second, if you were to select a multi-port device, like the NES Four
Score, the core will set the other port to the Four Score device as
well, and the GUIs query connected() right after any call to connect(),
so it gets updated without needing a system for the emulation core to
send messages alerting the GUI of changes.

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

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.

So only bsnes the automated overscan cropping option. In higan, you can
crop however many lines you like from the top or bottom of the image.
But for bsnes, it automatically eats sixteen lines. My view right now is
that if bsnes is meant to be the casual gaming emulator, that it should
eat line 224 in this mode. Most games show content here, but because of
the way the SNES PPU works, the very last line ends up on its very own
tile row (line 0 isn't rendered), if the scroll registers don't account
for it. There's a small number of games that will draw junk data to the
very last scanline of the frame as a result of this. So I chose, at
least for now, to hide it. Users can obviously disable overscan cropping
to see this scanline. I'm open to being convinced not to do this, if
someone has a compelling reason.
We're pretty much screwed one way or the other with no overscan masking.
If we output 239 lines, then most games will render 7 blank lines + 224
drawn lines + 8 blank lines, and the black top and bottom aren't
centered. But if we output 240 lines to get 8 + 224 + 8, then games that
do use overscan will have a blank line at the very bottom of the window.
I'm also trying out a modified cheat code file format. It's been forever
since I bothered to look at it, and the “cartridge” parent node doesn't
match what I'm doing with trying to rename “cartridge” to “game” in
manifests. And indeed, the idea of requiring a root node is rather
superfluous for a cheat code file. Current format looks like this:
cheat
description: foo
code: 7e2000=20+7e2001=30?40
enabled
cheat
description: bar
code: 7e4000=80
Open to discussing this, and I'd like to sync up with Snes9X before they
push out a new release, and I'll agree to finalize and never change this
format again.
I chose to use .cht for the extension when using game files (eg
gamename.cht)

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.
byuu says:
Changelog:
- sfc/ppu-fast: everything other than vertical mosaic and interlace

Games are quite playable now, and you're welcome to try things out, but
please don't report bugs yet. It's still too early for that.

Changelog:
- sfc/ppu-fast: added a barebones background renderer; very incomplete
Right now, the 2bpp Mega Man X2 splash screen is rendering correctly,
but everything else looks really garbled. I'm thinking my tile cache
conversions from 4bpp to bitmap pixels is wrong, but I'm not seeing any
obvious issues.
If anyone wants to take a look at it, I'd appreciate it. The renderer is
mostly modeled after ppu-performance's.

Changelog:
- nall/GNUmakefile: fixed findstring parameter arguments [Screwtape]
- nall/Windows: always include -mthreads -lpthread for all

- nall/memory: code restructuring
I really wanted to work on the new PPU today, but I thought I'd spend a
few minutes making some minor improvements to nall::memory, that was
five and a half hours ago. Now I have a 67KiB diff of changes. Sigh.

Changelog:
- SNES: started on skeleton of the new parallel PPU core
To build the new PPU core, set profile=fast via GNU make. The old core
is profile=accurate.
The names of the profiles, and the name of the folder for the fast PPU
are subject to change.
The new PPU core doesn't do anything but demonstrate the proof of
concept: every scanline, make a copy of all the PPU registers and CGRAM.
Share the VRAM and OAM. Batch render all scanlines at once using OpenMP
at the end of each frame and blit the result.
With no PPU core at all, bsnes runs 91% faster than with the accuracy
PPU (230fps vs 120fps.) That's the absolute theoretical best-case
scenario. With the skeleton in place, we're already around 220fps. It'll
go down more as the PPU line renderer starts to do real work. I don't
know where things will end up yet. I suppose we'll find out in time.
My own copy of TDM/GCC can't use OpenMP on Windows, so ... it won't
parallelize if you build with that. I'm going to have to switch to a
different MinGW distribution once this is complete, I suppose.

Changelog:
* yes.
But seriously, a list of changes on a pre-alpha GUI is going to get annoying.
Basically, work on embedding stuff in the binary, firmware loading (both
appended to the ROM and in a firmware/ subfolder) added, SGB games can be
loaded, config file holds more values for driver settings, added ruby drivers to
other platforms, etc.
byuu says:
Changelog:
- created new bsnes target (it currently does nothing)
- Super Famicom: fixed BS Memory pack support in the MCC emulation
- icarus: fixed manifest-free support for BS Memory flash-based
cartridges
- icarus: database improvements
byuu says:
Changelog:
- higan: target-tomoko has been renamed to target-higan
- Super Famicom: event has been renamed to
processor(architecture=uPD78214)
- Super Famicom: SNES-EVENT supported once more; under board IDs
EVENT-CC92 and EVENT-PF94
- Super Famicom: SNES-EVENT preliminarily set up to use DIP switch
settings ala the Nintendo Super System (incomplete)
- Super Famicom: MCC PSRAM moved inside the MCU, as it is remappable
- Super Famicom: MCC emulation rewritten from scratch; it is now
vastly more accurate than before
- Super Famicom: added BSC-1A5B9P-01 board definition to database;
corrected BS-MCC-RAM board definition
- Super Famicom: moved SHVC-LN3B-01 RAM outside of
processor(identifier=SDD1)
- higan: when selecting a default game to load for a new system entry,
it will change the system option to match the media type
- higan: the load text box on the system entry window is now editable;
can be used to erase entries
- icarus: fixed bug in Famicom importing
- icarus: importing unappended SNES coprocessor firmware will now
rename the firmware properly
- hiro/GTK,Qt: WM_CLASS is now set correctly in `argv[0]`, so
applications should show “higan”, “icarus” instead of “hiro” now
Note: if you wish to run the BS-X town cartridge, the database currently
lists the download RAM as type “PSRAM”. This needs to be changed to
“RAM” in order to load properly. Otherwise, the emulator will bomb
out on the load window, because BSC-1A5B9P-01 expects PSRAM to always be
present, but it won't find it with the wrong memory type. I'll correct
this in the database in a later release. For now, you can copy the game
portion of the manifest to a new manifest.bml file and drop it into the
gamepak folder until I fix the database.
byuu says:
Changelog:
- Super Famicom: fixed loading of BS Memory and Sufami Turbo
cartridges
- Super Famicom: renamed NSS to DIP; as that's really all it is, it's
not true NSS emulation
- Super Famicom: slot loading now happens inside of board parsing
instead of generically in loadCartridge()
- Super Famicom: BS-X cartridges with flash memory now serialize their
data and write it out to disk¹
- icarus: fixed Famicom game importing (hopefully) and set file import
title to “Load ROM File”
¹: there's no emulation of write commands yet, so the data is never
going to change anyway. This is just in preparation for more advanced
emulation of BS Memory cartridges.
byuu says:
Changelog:
- Super Famicom: everything outside of Nintendo Super System, Campus
Challenge '92 and Powerfest '94 should play
- Super Famicom: removed RAM from coprocessor/event (should use global
RAM)
- Super Famicom: removed RAM from SDD1 (should use global RAM)
- icarus: fixed Super Famicom game importing [hex_usr]
Also worth reminding that you'll need to disable database lookup in
order to run the BS-X Town cartridge right now. Plus, Star Ocean's
database entry still has the RAM in the wrong spot. The MSU1 code is not
looking at the right locations for data, so it's not going to work in
this release either.
I need to figure out what to call coprocessor/event and coprocessor/nss,
as neither are slots or processors like everything else.
Outside of those issues, all games for all systems should be playable,
at least to the extent they were in v106.
byuu says:
Changelog:
- major restructuring of board manifests
- cleanup of generic board names
- Super Famicom: updates to SA1, SuperFX, Cx4, SPC7110, EpsonRTC,
SharpRTC load/save code
- Super Famicom: added experimental SuperFX plot dithering fix
[qwertymodo]
- higan, icarus: rename shared folders to lowercase names; put .sys
folders into new subfolder
- Video Shaders/ → shaders/
- Database/ → database/
- Firmware/ → firmware/
- \*.sys/ → systems/\*.sys/
So right now, only standard SNES games, SA-1, SuperFX, and Cx4 games
load. I have not tested SPC7110 or RTC support, because icarus import
seems to be completely broken? It's creating blank folders when I try it
now. I'll have to fix that ...
Since we are now up to thirteen systems, I've put the .sys folders into
a subfolder. This should declutter the main higan-windows release folder
a good deal. Linux users will need to re-run make install, or manually
move things into a new systems/ subfolder.
Same goes for icarus: lowercase the database/ and firmware/ folders or
re-run make install.
I don't know if qwertymodo's SuperFX fix is exactly correct or not.
Hopefully it is, but I didn't write a test ROM or anything to be
certain. Since SuperFX games should run, if people could please play
through some of them and look for any regressions, that'd be very much
appreciated.

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:
- Emulator: update to final manifest syntax
- Super Famicom: new board syntax (still experimental)
- Super Famicom: match (manufacturer.)category.type instead of

subtype matches
- Sufami Turbo ROM/RAM nodes are part of separate gamepaks; need to
refactor this
byuu says:
Changelog:
- manifest: memory/battery now resides under type at
memory/type/battery
- genius: volatile option changed to battery; auto-disables when not
RAM or RTC type
- higan: added new Emulator::Game class to parse manifests for all
emulated systems consistently
- Super Famicom: board manifest appended to manifest viewer now
- Super Famicom: cartridge class updated to use Emulator::Game objects
- hiro: improve suppression of userland callbacks once
Application::quit() is called
- this fixes a crash in genius when closing the window with a tree
view item selected
My intention is to remove Emulator::Interface::sha256(), as it's not
really useful. They'll be removed from save states as well. I never
bothered validating the SHA256 within them, because that'd be really
annoying for ROM hackers.
I also intend to rename Emulator::Interface::title() to label() instead.
Most everything is still broken. The SNES still needs all the board
definitions updated, all the other cores need to move to using
Emulator::Game.
byuu says:
Changelog:
- higan, icarus, genius: new manifest syntax (work in progress)
Pretty much only LoROM and HiROM SNES games will load right now, and RAM
will only work right if the save.ram file already exists to pull its
file size from (a temporary cheap hack was used.)
Basically, I'm just getting this out there for evaluation.
One minor errata is that I switched icarus to using “memory/battery” to
indicate battery-backed RAM, whereas genius still uses “memory/volatile”
to indicate non-battery-backed RAM.
I intend to make it “memory/battery” in genius, and have the field
auto-enable when RAM or RTC is selected for type (obviously allowing it
to be unchecked for volatile memory.)
I need to update all 64 production boards, and 25 of 29 generic boards,
to use the new slot syntax; and I also need to update every single core
in higan to use the new manifest game syntax. I want to build out a
generic manifest game parser that all emulation cores will use.
Once I finish this, I'll also need to write a database converter to
update all of my licensed game dumps to the new database syntax.
I also need to write up something for doc.byuu.org explaining the new
manifest game syntax. The manifest board syntax will still be “internal”
and subject to revisions, but once v107 is out, the gamepak manifest
format will be set in stone sans extensions.

Changelog:
- Game Boy: fixed RAM/RTC saving¹
- Super Famicom: ICD2 renamed to ICD (there exists an SGB prototype
with a functionally identical ICD1)
- Sufami Turbo: removed short-circuiting when loading an unlinkable
cartridge into slot A²
- Super Game Boy: the 20971520hz clock of the SGB2 is now emulated
- Super Famicom: BSC-1Lxx (SA1) boards now prompt for BS memory
cartridges; and can make use of them³
- Super Famicom: fixed a potential for out-of-bounds reads with BS
Memory flash carts
¹: I'm using a gross hack of replacing `type: ` with `type:` so that
`memory(type=...)` will match without the extra spaces. I need to
think about whether I want the BPath query syntax to strip whitespace or
not. But longer term, I want to finalize game/memory's design, and build
a higan/emulation/manifest parser that produces a nicer interface to
reading manifests for all cores, which will make this irrelevant for
higan anyway.
²: I don't think it's appropriate for higan to enforce this. Nothing
stops you from inserting games that can't be linked into a real Sufami
Turbo. I do short-circuit if you cancel the first load, but I may allow
loading an empty slot A with a populated slot B. I think the BIOS does
something when you do that. Probably just yells at you.
³: I know it's emulated correctly now, but I still don't know what
the heck changes when you load the SD Gundam G Next - Unit & Map
Collection BS Memory cartridge with SD Gundam G Next to actually test
it.
byuu says:
Changelog:
- Super Game Boy: for the 50th time, higan won't segfault if you
cancel the Game Boy cartridge load request
- icarus: moved to new manifest syntax for all remaining systems
- Game Boy: moved to new manifest syntax
Errata:
- Game Boy: save RAM does not appear to be working for some reason
- Famicom: higan won't even start to run this system; it just acts
like a cartridge was never loaded ...
- cores outside of the Super Famicom and Game Boy/Color will not run
due to icarus/higan manifest syntax differences
byuu says:
Changelog:
- Super Famicom: added remaining generic board types
- icarus: improved Super Famicom heuristics
- icarus: reworked BS Memory heuristics
- icarus: reworked Sufami Turbo heuristics
Notes: this is really complicated, and is going to take a long time to
work 100% smoothly again.
Starting off, I am trying to get rid of the weird edge case zero-byte
SRAM mapping for the Cx4. It has the RAM region present, but returns
logic low (0x00) instead of open bus, when SRAM isn't present. I started
by making it `map=ram` instead of `ram/map`, which is gross, and then it ended
up detecing the map tag ending in RAM and pulling the Cx4 data RAM into that
slot. Ugh. The preservation board mapping is still as it was before and will
need to be updated once I get the syntax down.
The BS Memory and Sufami Turbo moving to the new `game/memory`
ending means I can't use the SuperFamicom::Cartridge::loadMemory
function that looks at the old-style rom/ram tags. Because I didn't
write more code, the result is those sub-carts won't load now.
The old heuristics were short-circuiting on SA1 before bothering with
BS-X slots, so that's why SD Gundam G-Next wasn't asking for a data
pack. The problem is, I don't know where the BS-X pack maps to on this
cartridge. It's at c0-ef on the other BS-X slotted cartridges, but
that's mapped to the SA1 on regular SA1 cartridges, so ... for now, it's
not actually mapped in.
I'm still struggling with naming conventions on all these boards. I'll
make a public post about that, though.
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: update to newer board markup syntax
- Super Famicom: update all mapped ROMs to be write-protected
- errata: SPC7110 set ram.writeProtect(true), I'll fix it in the
next WIP
- icarus: rewrote the Super Famicom heuristics module from scratch
Instead of icarus heuristics generating higan-specific mappings, it now
generates generic board IDs that can be used by any emulator. I had
originally planned to print out real PCB ID codes here, but these board
mappings are meant to be more generic, and I don't want them to look
real. The pseudo-codes are easy to parse, for example: `DSP-LOROM-NVRAM`
for Super Mario Kart, `SUPERFX-RAM` for Doom.
I'm going to make a `Boards (Generic).bml` file that will contain mapping
definitions for every board. Until this is done, any games not in the SNES
preservation database will fail to play because the mapping information is
now missing.
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.

and onethirdxcubed for both finding this:
http://wiki.nesdev.com/w/index.php?title=CPU_power_up_state&diff=11711&oldid=11184
I'll remove this in the next WIP.
Loading and unloading the RTC is a little odd, since it's normally
always powered in the first place. What we want, and what the load()
functions really do, is to resync using the saved timestamps or
reset it. unload() proper doesn't do anything.
However, an interface refactoring after v098 reordered the above
operations, and this (along with a typo, shh!) was causing the already
synced time to be cleared.
I've added checks so that whenever rtc.ram can't be found, load() gets
called with empty arguments to initialise the defaults (like putting
in a fresh battery).

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.
