Raw Normal View History

Update to v088r07 release. byuu says: (r05 and r06 were save points between large core modifications) I would really appreciate extensive regression testing (especially around SuperFX, Cx4, ST018, DSP-n, ST-01n, NES, GB) at this point. The most critical core changes should be completed now. And it was an unbelievable amount of restructuring. Changelog: - SuperFX core moved to Processor::GSU - SNES::CPU core moved to Processor::R65816 - SNES::SMP core moved to Processor::SPC700 - NES::CPU core renamed to Processor::R6502 - use filestream to load RAM files from interface - save states store SHA256 instead of CRC32 (CRC32 usage removed entirely from bsnes) - nes/ -> fc/ and NES -> FC - snes/ -> sfc/ and SNES -> SFC - SuperFamicom::MappedRAM::copy uses stream instead of data+size - Linux port uses gcc-4.7 (still using only gcc-4.6 subset, so you can make a gcc-4.6 symlink for now if you like.) - all profiles and all targets compile and work properly All eight instruction set cores have been moved to processor/ now. Consistency's a wonderful thing. The last remnants of NES/SNES are now limited to target-ui code; and the nall/(system) folder names. I'm building with gcc-4.7 on my Linux box now because the resultant binaries are up to 20% faster (seriously) than gcc-4.6.

Update to v085r03 release. byuu says: Changelog: - fixed cursor being visible under Metacity window manager (hopefully doesn't cause regression with other WMs) - show normal cursor when using SDL video driver - added menu accelerators (meh, why not?) - removed debugvirtual, ChipDebugger and chip/debugger functionality entirely - alt/smp disassembler moved up - fixed alt/smp incw/decw instructions (unsigned->uint16 for internal variables) My plan going forward for a debugger is not to hardcode functionality that causes the 10-15% slowdown right into the emulator itself. Instead, I'm going to make a callback class, which will be a specialized version of nall::function: - can call function even if not assigned (results in no-op, return type must have a trivial default constructor) - if compiled without #define DEBUGGER, the entire thing turns into a huge no-op; and will be eliminated entirely when compiled - strategically place the functions: cb_step, cb_read, cb_write, etc. From here, the ui-debugger GUI will bind the callbacks, implement breakpoint checking, usage table generation, etc itself. I'll probably have to add some breakout commands to exit the emulation core prior to a frame event in some cases as well. I didn't initially want any debugger-related stuff in the base cores, but the #if debugger sCPUDebugger #else sCPU #endif stuff was already more of a burden than this will be.

Update to v097r29 release. byuu says: Changelog: - fixed DAS instruction (Judgment Silversword score) - fixed [VH]TMR_FREQ writes (Judgement Silversword audio after area 20) - fixed initialization of SP (fixes seven games that were hanging on startup) - added SER_STATUS and SER_DATA stubs (fixes four games that were hanging on startup) - initialized IEEP data (fixes Super Robot Taisen Compact 2 series) - note: you'll need to delete your internal.com in WonderSwan (Color).sys folders - fixed CMPS and SCAS termination condition (fixes serious bugs in four games) - set read/writeCompleted flags for EEPROM status (fixes Tetsujin 28 Gou) - major code cleanups to SFC/R65816 and SFC/CPU - mostly refactored disassembler to output strings instead of using char* buffer - unrolled all the subfolders on sfc/cpu to a single directory - corrected casing for all of sfc/cpu and a large portion of processor/r65816 I kind of went overboard on the code cleanup with this WIP. Hopefully nothing broke. Any testing one can do with the SFC accuracy core would be greatly appreciated. There's still an absolutely huge amount of work left to go, but I do want to eventually refresh the entire codebase to my current coding style, which is extremely different from stuff that's been in higan mostly untouched since ~2006 or so. It's dangerous and fickle work, but if I don't do it, then the code will be a jumbled mess of several different styles.

Update to v099r03 release. byuu says: Changelog: - finished cleaning up the SFC core to my new coding conventions - removed sfc/controller/usart (superseded by 21fx) - hid Synchronize Video option from the menu (still in the configuration file) Pretty much the only minor detail left is some variable names in the SA-1 core that really won't look good at all if I move to camelCase, so I'll have to rethink how I handle those. It's probably a good area to attempt using BitFields, to see how it impacts performance. But I'll do that in a test branch first. But for the most part, this should be the end of the gigantic diffs (this one was 174KiB), at least for the SFC/WS cores. Still have the FC/GB/GBA cores to clean up more fully. Assuming we don't spot any new regressions, we should be ~95% out of the woods on code cleanups breaking things.

Update to v079r06 release. byuu says: It does add some more code to the CPU::step() function, so performance probably went down actually, by about 1%. Removing the input.tick() call didn't compensate as much as I'd hoped. Hooked up Super Scope and Justifier support. The good news is that the Justifier alignment doesn't get fucked up anymore when you go off-screen. Never could fix that in the old version. The bad news is that it takes a major speed hit for the time being. I need to figure out how to run the CPU and input threads out of order. Every time I try, the input gets thrown off by most of a scanline. Right now, I'm forced to sync constantly to get the latching position really accurate. But worst case, I can cut the syncs down by skipping large chunks around the cursor position, +/-40 clock cycles. So it's only temporarily slow. Lastly, killed the old Input class, merged Controllers class into it. I actually like Controllers as a name better, but it doesn't jive with video/audio/input, so oh well.

Update to v097r13 release. byuu says: I refactored my schedulers. Added about ten lines to each scheduler, and removed about 100 lines of calling into internal state in the scheduler for the FC,SFC cores and about 30-40 lines for the other cores. All of its state is now private. Also reworked all of the entry points to static auto Enter() and auto main(). Where Enter() handles all the synchronization stuff, and main() doesn't need the while(true); loop forcing another layer of indentation everywhere. Took a few hours to do, but totally worth it. I'm surprised I didn't do this sooner. Also updated icarus gmake install rule to copy over the database.

Update to v099r03 release. byuu says: Changelog: - finished cleaning up the SFC core to my new coding conventions - removed sfc/controller/usart (superseded by 21fx) - hid Synchronize Video option from the menu (still in the configuration file) Pretty much the only minor detail left is some variable names in the SA-1 core that really won't look good at all if I move to camelCase, so I'll have to rethink how I handle those. It's probably a good area to attempt using BitFields, to see how it impacts performance. But I'll do that in a test branch first. But for the most part, this should be the end of the gigantic diffs (this one was 174KiB), at least for the SFC/WS cores. Still have the FC/GB/GBA cores to clean up more fully. Assuming we don't spot any new regressions, we should be ~95% out of the woods on code cleanups breaking things.

Update to v098r11 release. byuu says: Changelog: - fixed nall/path.hpp compilation issue - fixed ruby/audio/xaudio header declaration compilation issue (again) - cleaned up xaudio2.hpp file to match my coding syntax (12.5% of the file was whitespace overkill) - added null terminator entry to nall/windows/utf8.hpp argc[] array - nall/windows/guid.hpp uses the Windows API for generating the GUID - this should stop all the bug reports where two nall users were generating GUIDs at the exact same second - fixed hiro/cocoa compilation issue with uint# types - fixed major higan/sfc Super Game Boy audio latency issue - fixed higan/sfc CPU core bug with pei, [dp], [dp]+y instructions - major cleanups to higan/processor/r65816 core - merged emulation/native-mode opcodes - use camel-case naming on memory.hpp functions - simplify address masking code for memory.hpp functions - simplify a few opcodes themselves (avoid redundant copies, etc) - rename regs.* to r.* to match modern convention of other CPU cores - removed device.order<> concept from Emulator::Interface - cores will now do the translation to make the job of the UI easier - fixed plurality naming of arrays in Emulator::Interface - example: emulator.ports[p].devices[d].inputs[i] - example: vector<Medium> media - probably more surprises Major show-stoppers to the next official release: - we need to work on GB core improvements: LY=153/0 case, multiple STAT IRQs case, GBC audio output regs, etc. - we need to re-add software cursors for light guns (Super Scope, Justifier) - after the above, we need to fix the turbo button for the Super Scope I really have no idea how I want to implement the light guns. Ideally, we'd want it in higan/video, so we can support the NES Zapper with the same code. But this isn't going to be easy, because only the SNES knows when its output is interlaced, and its resolutions can vary as {256,512}x{224,240,448,480} which requires pixel doubling that was hard-coded to the SNES-specific behavior, but isn't appropriate to be exposed in higan/video.

Hopefully nothing broke. Any testing one can do with the SFC accuracy core would be greatly appreciated. There's still an absolutely huge amount of work left to go, but I do want to eventually refresh the entire codebase to my current coding style, which is extremely different from stuff that's been in higan mostly untouched since ~2006 or so. It's dangerous and fickle work, but if I don't do it, then the code will be a jumbled mess of several different styles.

Update to v097r32 release. byuu says: Changelog: - bsnes-accuracy emulates reset vector properly[1] - bsnes-balanced compiles once more - bsnes-performance compiles once more The balanced and performance profiles are fixed for the last time. They will be removed for v098r01. Please test this WIP as much as you can. I intend to release v098 soon. I know save states are a little unstable for the WS/WSC, but they work well enough for a release. If I can't figure it out soon, I'm going to post v098 anyway. [1] this one's been a really long time coming, but ... one of the bugs I found when I translated Tekkaman Blade was that my translation patch would crash every now and again when you hit the reset button on a real SNES, but it always worked upon power on. Turns out that while power-on initializes the stack register to $01ff, reset does things a little bit differently. Reset actually triggers the reset interrupt vector after putting the CPU into emulation mode, but it doesn't initialize the stack pointer. The net effect is that the stack high byte is set to $01, and the low byte is left as it was. And then the reset vector runs, which pushes the low 16-bits of the program counter, plus the processor flags, onto the stack frame. So you can actually tell where the game was at when the system was reset ... sort of. It's a really weird behavior to be sure. But here's the catch: say you're hacking a game, and so you hook the reset vector with jsl showMyTranslationCreditsSplashScreen, and inside this new subroutine, you then perform whatever bytes you hijacked, and then initialize the stack frame to go about your business drawing the screen, and when you're done, you return via rtl. Generally, this works fine. But if S={0100, 0101, or 0102}, then the stack will wrap due to being in emulation mode at reset. So it will write to {0100, 01ff, 01fe}. But now in your subroutine, you enable native mode. So when you return from your subroutine hijack, it reads the return address from {01ff, 0200, 0201} instead of the expected {01ff, 0100, 0101}. Thus, you get an invalid address back, and you "return" to the wrong location, and your program dies. The odds of this happening depend on how the game handles S, but generally speaking, it's a ~1:85 chance. By emulating this behavior, I'll likely expose this bug in many ROM hacks that do splash screen hooks like this, including my own Tekkaman Blade translation. And it's also very possible that there are commercial games that screw this up as well. But, it's what the real system does. So if any crashes start happening as of this WIP upon resetting the game, well ... it'd happen on real hardware, too.

Update to v097r13 release. byuu says: I refactored my schedulers. Added about ten lines to each scheduler, and removed about 100 lines of calling into internal state in the scheduler for the FC,SFC cores and about 30-40 lines for the other cores. All of its state is now private. Also reworked all of the entry points to static auto Enter() and auto main(). Where Enter() handles all the synchronization stuff, and main() doesn't need the while(true); loop forcing another layer of indentation everywhere. Took a few hours to do, but totally worth it. I'm surprised I didn't do this sooner. Also updated icarus gmake install rule to copy over the database.

Fixed locally.) Note: SNES is the only system with multiple controller/expansion port options, and as such is the only one with a "None" option. Because it's shared by the controller and expansion port, it ends up sorted first in the list. This means that on your first run, you'll need to go to Super Famicom->Controller Port 1 and select "Gamepad", otherwise input won't work. Also note that changing the expansion port device requires loading a new cart. Unlike controllers, you aren't meant to hotplug expansion port devices.

We will have to perform basic color conversion inside the core. As such, the current plan is to create some sort of Emulator::Settings interface. With that, I'll connect an option for color correction, which will be on by default. For FC/SFC, that will mean gamma correction (darker / stronger colors), and for GB/GBC/GBA, it will mean simulating the weird brightness levels of the displays. I am undecided on whether to use pea soup green for the GB or not. By not doing so, it'll be easier for the display emulation shader to do it.

Update to v098r11 release. byuu says: Changelog: - fixed nall/path.hpp compilation issue - fixed ruby/audio/xaudio header declaration compilation issue (again) - cleaned up xaudio2.hpp file to match my coding syntax (12.5% of the file was whitespace overkill) - added null terminator entry to nall/windows/utf8.hpp argc[] array - nall/windows/guid.hpp uses the Windows API for generating the GUID - this should stop all the bug reports where two nall users were generating GUIDs at the exact same second - fixed hiro/cocoa compilation issue with uint# types - fixed major higan/sfc Super Game Boy audio latency issue - fixed higan/sfc CPU core bug with pei, [dp], [dp]+y instructions - major cleanups to higan/processor/r65816 core - merged emulation/native-mode opcodes - use camel-case naming on memory.hpp functions - simplify address masking code for memory.hpp functions - simplify a few opcodes themselves (avoid redundant copies, etc) - rename regs.* to r.* to match modern convention of other CPU cores - removed device.order<> concept from Emulator::Interface - cores will now do the translation to make the job of the UI easier - fixed plurality naming of arrays in Emulator::Interface - example: emulator.ports[p].devices[d].inputs[i] - example: vector<Medium> media - probably more surprises Major show-stoppers to the next official release: - we need to work on GB core improvements: LY=153/0 case, multiple STAT IRQs case, GBC audio output regs, etc. - we need to re-add software cursors for light guns (Super Scope, Justifier) - after the above, we need to fix the turbo button for the Super Scope I really have no idea how I want to implement the light guns. Ideally, we'd want it in higan/video, so we can support the NES Zapper with the same code. But this isn't going to be easy, because only the SNES knows when its output is interlaced, and its resolutions can vary as {256,512}x{224,240,448,480} which requires pixel doubling that was hard-coded to the SNES-specific behavior, but isn't appropriate to be exposed in higan/video.

Update to v097r32 release. byuu says: Changelog: - bsnes-accuracy emulates reset vector properly[1] - bsnes-balanced compiles once more - bsnes-performance compiles once more The balanced and performance profiles are fixed for the last time. They will be removed for v098r01. Please test this WIP as much as you can. I intend to release v098 soon. I know save states are a little unstable for the WS/WSC, but they work well enough for a release. If I can't figure it out soon, I'm going to post v098 anyway. [1] this one's been a really long time coming, but ... one of the bugs I found when I translated Tekkaman Blade was that my translation patch would crash every now and again when you hit the reset button on a real SNES, but it always worked upon power on. Turns out that while power-on initializes the stack register to $01ff, reset does things a little bit differently. Reset actually triggers the reset interrupt vector after putting the CPU into emulation mode, but it doesn't initialize the stack pointer. The net effect is that the stack high byte is set to $01, and the low byte is left as it was. And then the reset vector runs, which pushes the low 16-bits of the program counter, plus the processor flags, onto the stack frame. So you can actually tell where the game was at when the system was reset ... sort of. It's a really weird behavior to be sure. But here's the catch: say you're hacking a game, and so you hook the reset vector with jsl showMyTranslationCreditsSplashScreen, and inside this new subroutine, you then perform whatever bytes you hijacked, and then initialize the stack frame to go about your business drawing the screen, and when you're done, you return via rtl. Generally, this works fine. But if S={0100, 0101, or 0102}, then the stack will wrap due to being in emulation mode at reset. So it will write to {0100, 01ff, 01fe}. But now in your subroutine, you enable native mode. So when you return from your subroutine hijack, it reads the return address from {01ff, 0200, 0201} instead of the expected {01ff, 0100, 0101}. Thus, you get an invalid address back, and you "return" to the wrong location, and your program dies. The odds of this happening depend on how the game handles S, but generally speaking, it's a ~1:85 chance. By emulating this behavior, I'll likely expose this bug in many ROM hacks that do splash screen hooks like this, including my own Tekkaman Blade translation. And it's also very possible that there are commercial games that screw this up as well. But, it's what the real system does. So if any crashes start happening as of this WIP upon resetting the game, well ... it'd happen on real hardware, too.

Fixed locally.) Note: SNES is the only system with multiple controller/expansion port options, and as such is the only one with a "None" option. Because it's shared by the controller and expansion port, it ends up sorted first in the list. This means that on your first run, you'll need to go to Super Famicom->Controller Port 1 and select "Gamepad", otherwise input won't work. Also note that changing the expansion port device requires loading a new cart. Unlike controllers, you aren't meant to hotplug expansion port devices.

Note: I added the expansion port devices to the same group as controller ports. I also had to move "None" to the top of the list. Before v096, I am going to have to add caching of port selections to the configuration file, check the proper default item in the system menu, and remove the items with no mappings from the input configuration window.

Update to 20100809 release. byuu says: This adds some sync.sh improvements to make it handle errors more gracefully. It also updates asnes a good bit. All of the four base processors now have all publicly accessible functions right at the top of the main headers, and everything else is private. This is to allow these headers to essentially take the place of the previous base classes in the old bsnes-merged format. So if there's something public there, you need to implement that exact function to make your own module. I removed the frame counter from the PPU, as it has nothing to do with emulation. That now resides inside the Qt -> SNES interface code. Quite amazing, I was actually saving the frame counter into the save state files before, yuck. Removed some baggage in the System class: it was friending a bunch of long-dead functions and classes. Forgot to re-add the CHEAT_SYSTEM define to info.hpp, so that's been put back.

Update to v098r03 release. byuu says: It took several hours, but I've rebuilt much of the SNES' bus memory mapping architecture. The new design unifies the cartridge string-based mapping ("00-3f,80-bf:8000-ffff") and internal bus.map calls. The map() function now has an accompanying unmap() function, and instead of a fixed 256 callbacks, it'll scan to find the first available slot. unmap() will free slots up when zero addresses reference a given slot. The controllers and expansion port are now both entirely dynamic. Instead of load/unload/power/reset, they only have the constructor (power/reset/load) and destructor (unload). What this means is you can now dynamically change even expansion port devices after the system is loaded. Note that this is incredibly dangerous and stupid, but ... oh well. The whole point of this was for 21fx. There's no way to change the expansion port device prior to loading a game, but if the 21fx isn't active, then the reset vector hijack won't work. Now you can load a 21fx game, change the expansion port device, and simply reset the system to active the device. The unification of design between controller port devices and expansion port devices is nice, and overall this results in a reduction of code (all of the Mapping stuff in Cartridge is gone, replaced with direct bus mapping.) And there's always the potential to expand this system more in the future now. The big missing feature right now is the ability to push/pop mappings. So if you look at how the 21fx does the reset vector, you might vomit a little bit. But ... it works. Also changed exit(0) to _exit(0) in the POSIX version of nall::execute. [The _exit(0) thing is an attempt to make higan not crash when it tries to launch icarus and it's not on $PATH. The theory is that higan forks, then the child tries to exec icarus and fails, so it exits, all the unique_ptrs clean up their resources and tell the X server to free things the parent process is still using. Calling _exit() prevents destructors from running, and seems to prevent the problem. -Ed.]

Update to v099r03 release. byuu says: Changelog: - finished cleaning up the SFC core to my new coding conventions - removed sfc/controller/usart (superseded by 21fx) - hid Synchronize Video option from the menu (still in the configuration file) Pretty much the only minor detail left is some variable names in the SA-1 core that really won't look good at all if I move to camelCase, so I'll have to rethink how I handle those. It's probably a good area to attempt using BitFields, to see how it impacts performance. But I'll do that in a test branch first. But for the most part, this should be the end of the gigantic diffs (this one was 174KiB), at least for the SFC/WS cores. Still have the FC/GB/GBA cores to clean up more fully. Assuming we don't spot any new regressions, we should be ~95% out of the woods on code cleanups breaking things.

Update to v098r03 release. byuu says: It took several hours, but I've rebuilt much of the SNES' bus memory mapping architecture. The new design unifies the cartridge string-based mapping ("00-3f,80-bf:8000-ffff") and internal bus.map calls. The map() function now has an accompanying unmap() function, and instead of a fixed 256 callbacks, it'll scan to find the first available slot. unmap() will free slots up when zero addresses reference a given slot. The controllers and expansion port are now both entirely dynamic. Instead of load/unload/power/reset, they only have the constructor (power/reset/load) and destructor (unload). What this means is you can now dynamically change even expansion port devices after the system is loaded. Note that this is incredibly dangerous and stupid, but ... oh well. The whole point of this was for 21fx. There's no way to change the expansion port device prior to loading a game, but if the 21fx isn't active, then the reset vector hijack won't work. Now you can load a 21fx game, change the expansion port device, and simply reset the system to active the device. The unification of design between controller port devices and expansion port devices is nice, and overall this results in a reduction of code (all of the Mapping stuff in Cartridge is gone, replaced with direct bus mapping.) And there's always the potential to expand this system more in the future now. The big missing feature right now is the ability to push/pop mappings. So if you look at how the 21fx does the reset vector, you might vomit a little bit. But ... it works. Also changed exit(0) to _exit(0) in the POSIX version of nall::execute. [The _exit(0) thing is an attempt to make higan not crash when it tries to launch icarus and it's not on $PATH. The theory is that higan forks, then the child tries to exec icarus and fails, so it exits, all the unique_ptrs clean up their resources and tell the X server to free things the parent process is still using. Calling _exit() prevents destructors from running, and seems to prevent the problem. -Ed.]

Hopefully nothing broke. Any testing one can do with the SFC accuracy core would be greatly appreciated. There's still an absolutely huge amount of work left to go, but I do want to eventually refresh the entire codebase to my current coding style, which is extremely different from stuff that's been in higan mostly untouched since ~2006 or so. It's dangerous and fickle work, but if I don't do it, then the code will be a jumbled mess of several different styles.

Update to v098r11 release. byuu says: Changelog: - fixed nall/path.hpp compilation issue - fixed ruby/audio/xaudio header declaration compilation issue (again) - cleaned up xaudio2.hpp file to match my coding syntax (12.5% of the file was whitespace overkill) - added null terminator entry to nall/windows/utf8.hpp argc[] array - nall/windows/guid.hpp uses the Windows API for generating the GUID - this should stop all the bug reports where two nall users were generating GUIDs at the exact same second - fixed hiro/cocoa compilation issue with uint# types - fixed major higan/sfc Super Game Boy audio latency issue - fixed higan/sfc CPU core bug with pei, [dp], [dp]+y instructions - major cleanups to higan/processor/r65816 core - merged emulation/native-mode opcodes - use camel-case naming on memory.hpp functions - simplify address masking code for memory.hpp functions - simplify a few opcodes themselves (avoid redundant copies, etc) - rename regs.* to r.* to match modern convention of other CPU cores - removed device.order<> concept from Emulator::Interface - cores will now do the translation to make the job of the UI easier - fixed plurality naming of arrays in Emulator::Interface - example: emulator.ports[p].devices[d].inputs[i] - example: vector<Medium> media - probably more surprises Major show-stoppers to the next official release: - we need to work on GB core improvements: LY=153/0 case, multiple STAT IRQs case, GBC audio output regs, etc. - we need to re-add software cursors for light guns (Super Scope, Justifier) - after the above, we need to fix the turbo button for the Super Scope I really have no idea how I want to implement the light guns. Ideally, we'd want it in higan/video, so we can support the NES Zapper with the same code. But this isn't going to be easy, because only the SNES knows when its output is interlaced, and its resolutions can vary as {256,512}x{224,240,448,480} which requires pixel doubling that was hard-coded to the SNES-specific behavior, but isn't appropriate to be exposed in higan/video.

Update to v097r29 release. byuu says: Changelog: - fixed DAS instruction (Judgment Silversword score) - fixed [VH]TMR_FREQ writes (Judgement Silversword audio after area 20) - fixed initialization of SP (fixes seven games that were hanging on startup) - added SER_STATUS and SER_DATA stubs (fixes four games that were hanging on startup) - initialized IEEP data (fixes Super Robot Taisen Compact 2 series) - note: you'll need to delete your internal.com in WonderSwan (Color).sys folders - fixed CMPS and SCAS termination condition (fixes serious bugs in four games) - set read/writeCompleted flags for EEPROM status (fixes Tetsujin 28 Gou) - major code cleanups to SFC/R65816 and SFC/CPU - mostly refactored disassembler to output strings instead of using char* buffer - unrolled all the subfolders on sfc/cpu to a single directory - corrected casing for all of sfc/cpu and a large portion of processor/r65816 I kind of went overboard on the code cleanup with this WIP. Hopefully nothing broke. Any testing one can do with the SFC accuracy core would be greatly appreciated. There's still an absolutely huge amount of work left to go, but I do want to eventually refresh the entire codebase to my current coding style, which is extremely different from stuff that's been in higan mostly untouched since ~2006 or so. It's dangerous and fickle work, but if I don't do it, then the code will be a jumbled mess of several different styles.

Update to v099r03 release. byuu says: Changelog: - finished cleaning up the SFC core to my new coding conventions - removed sfc/controller/usart (superseded by 21fx) - hid Synchronize Video option from the menu (still in the configuration file) Pretty much the only minor detail left is some variable names in the SA-1 core that really won't look good at all if I move to camelCase, so I'll have to rethink how I handle those. It's probably a good area to attempt using BitFields, to see how it impacts performance. But I'll do that in a test branch first. But for the most part, this should be the end of the gigantic diffs (this one was 174KiB), at least for the SFC/WS cores. Still have the FC/GB/GBA cores to clean up more fully. Assuming we don't spot any new regressions, we should be ~95% out of the woods on code cleanups breaking things.
