Update to v099r14 release. byuu says: Changelog: - (u)int(max,ptr) abbreviations removed; use _t suffix now [didn't feel like they were contributing enough to be worth it] - cleaned up nall::integer,natural,real functionality - toInteger, toNatural, toReal for parsing strings to numbers - fromInteger, fromNatural, fromReal for creating strings from numbers - (string,Markup::Node,SQL-based-classes)::(integer,natural,real) left unchanged - template<typename T> numeral(T value, long padding, char padchar) -> string for print() formatting - deduces integer,natural,real based on T ... cast the value if you want to override - there still exists binary,octal,hex,pointer for explicit print() formatting - lstring -> string_vector [but using lstring = string_vector; is declared] - would be nice to remove the using lstring eventually ... but that'd probably require 10,000 lines of changes >_> - format -> string_format [no using here; format was too ambiguous] - using integer = Integer<sizeof(int)*8>; and using natural = Natural<sizeof(uint)*8>; declared - for consistency with boolean. These three are meant for creating zero-initialized values implicitly (various uses) - R65816::io() -> idle() and SPC700::io() -> idle() [more clear; frees up struct IO {} io; naming] - SFC CPU, PPU, SMP use struct IO {} io; over struct (Status,Registers) {} (status,registers); now - still some CPU::Status status values ... they didn't really fit into IO functionality ... will have to think about this more - SFC CPU, PPU, SMP now use step() exclusively instead of addClocks() calling into step() - SFC CPU joypad1_bits, joypad2_bits were unused; killed them - SFC PPU CGRAM moved into PPU::Screen; since nothing else uses it - SFC PPU OAM moved into PPU::Object; since nothing else uses it - the raw uint8[544] array is gone. OAM::read() constructs values from the OAM::Object[512] table now - this avoids having to determine how we want to sub-divide the two OAM memory sections - this also eliminates the OAM::synchronize() functionality - probably more I'm forgetting The FPS fluctuations are driving me insane. This WIP went from 128fps to 137fps. Settled on 133.5fps for the final build. But nothing I changed should have affected performance at all. This level of fluctuation makes it damn near impossible to know whether I'm speeding things up or slowing things down with changes.

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.

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 v102r24 release. byuu says Changelog: - FC: fixed three MOS6502 regressions [hex\_usr] - GBA: return fetched instruction instead of 0 for unmapped MMIO (passes all of endrift's I/O tests) - MD: fix VDP control port read Vblank bit to test screen height instead of hard-code 240 (fixes Phantasy Star IV) - MD: swap USP,SSP when executing an exception (allows Super Street Fighter II to run; but no sprites visible yet) - MD: grant 68K access to Z80 bus on reset (fixes vdpdoc demo ROM from freezing immediately) - SFC: reads from $00-3f,80-bf:4000-43ff no longer update MDR [p4plus2] - SFC: massive, eight-hour cleanup of WDC65816 CPU core ... still not complete The big change this time around is the SFC CPU core. I've renamed everything from R65816 to WDC65816, and then went through and tried to clean up the code as much as possible. This core is so much larger than the 6502 core that I chose cleaning up the code to rewriting it. First off, I really don't care for the BitRange style functionality. It was an interesting experiment, but its fatal flaw are that the types are just bizarre, which makes them hard to pass around generically to other functions as arguments. So I went back to the list of bools for flags, and union/struct blocks for the registers. Next, I renamed all of the functions to be more descriptive: eg `op_read_idpx_w` becomes `instructionIndexedIndirectRead16`. `op_adc_b` becomes `algorithmADC8`. And so forth. I eliminated about ten instructions because they were functionally identical sans the index, so I just added a uint index=0 parameter to said functions. I added a few new ones (adjust→INC,DEC; pflag→REP,SEP) where it seemed appropriate. I cleaned up the disaster of the instruction switch table into something a whole lot more elegant without all the weird argument decoding nonsense (still need M vs X variants to avoid having to have 4-5 separate switch tables, but all the F/I flags are gone now); and made some things saner, like the flag clear/set and branch conditions, now that I have normal types for flags and registers once again. I renamed all of the memory access functions to be more descriptive to what they're doing: eg writeSP→push, readPC→fetch, writeDP→writeDirect, etc. Eliminated some of the special read/write modes that were only used in one single instruction. I started to clean up some of the actual instructions themselves, but haven't really accomplished much here. The big thing I want to do is get rid of the global state (aa, rd, iaddr, etc) and instead use local variables like I am doing with my other 65xx CPU cores now. But this will take some time ... the algorithm functions depend on rd to be set to work on them, rather than taking arguments. So I'll need to rework that. And then lastly, the disassembler is still a mess. I want to finish the CPU cleanups, and then post a new WIP, and then rewrite the disassembler after that. The reason being ... I want a WIP that can generate identical trace logs to older versions, in case the CPU cleanup causes any regressions. That way I can more easily spot the errors. Oh ... and a bit of good news. v102 was running at ~140fps on the SNES core. With the new support to suspend/resume WAI/STP, plus the internal CPU registers not updating the MDR, the framerate dropped to ~132fps. But with the CPU cleanups, performance went back to ~140fps. So, hooray. Of course, without those two other improvements, we'd have ended up at possibly ~146-148fps, but oh well.

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 v099r14 release. byuu says: Changelog: - (u)int(max,ptr) abbreviations removed; use _t suffix now [didn't feel like they were contributing enough to be worth it] - cleaned up nall::integer,natural,real functionality - toInteger, toNatural, toReal for parsing strings to numbers - fromInteger, fromNatural, fromReal for creating strings from numbers - (string,Markup::Node,SQL-based-classes)::(integer,natural,real) left unchanged - template<typename T> numeral(T value, long padding, char padchar) -> string for print() formatting - deduces integer,natural,real based on T ... cast the value if you want to override - there still exists binary,octal,hex,pointer for explicit print() formatting - lstring -> string_vector [but using lstring = string_vector; is declared] - would be nice to remove the using lstring eventually ... but that'd probably require 10,000 lines of changes >_> - format -> string_format [no using here; format was too ambiguous] - using integer = Integer<sizeof(int)*8>; and using natural = Natural<sizeof(uint)*8>; declared - for consistency with boolean. These three are meant for creating zero-initialized values implicitly (various uses) - R65816::io() -> idle() and SPC700::io() -> idle() [more clear; frees up struct IO {} io; naming] - SFC CPU, PPU, SMP use struct IO {} io; over struct (Status,Registers) {} (status,registers); now - still some CPU::Status status values ... they didn't really fit into IO functionality ... will have to think about this more - SFC CPU, PPU, SMP now use step() exclusively instead of addClocks() calling into step() - SFC CPU joypad1_bits, joypad2_bits were unused; killed them - SFC PPU CGRAM moved into PPU::Screen; since nothing else uses it - SFC PPU OAM moved into PPU::Object; since nothing else uses it - the raw uint8[544] array is gone. OAM::read() constructs values from the OAM::Object[512] table now - this avoids having to determine how we want to sub-divide the two OAM memory sections - this also eliminates the OAM::synchronize() functionality - probably more I'm forgetting The FPS fluctuations are driving me insane. This WIP went from 128fps to 137fps. Settled on 133.5fps for the final build. But nothing I changed should have affected performance at all. This level of fluctuation makes it damn near impossible to know whether I'm speeding things up or slowing things down with changes.

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 v097r15 release. byuu says: Changelog: - higan now uses Natural<Size>/Integer<Size> for its internal types - Super Famicom emulation now uses uint24 instead of uint for bus addresses (it's a 24-bit bus) - cleaned up gb/apu MMIO writes - cleaned up sfc/coprocessor/msu1 MMIO writes - ~3% speed penalty I've wanted to do that 24-bit bus thing for so long, but have always been afraid of the speed impact. It's probably going to hurt balanced/performance once they compile again, but it wasn't significant enough to harm the accuracy core's frame rate, thankfully. Only lost one frame per second. The GBA core handlers are clearly going to take a lot more work. The bit-ranges will make it substantially easier to handle, though. Lots of 32-bit registers where certain values span multiple bytes, but we have to be able to read/write at byte-granularity.

Update to v100r05 release. byuu says: Alright, I'm definitely going to need to find some people willing to tolerate my questions on this chip, so I'm going to go ahead and announce I'm working on this I guess. This core is way too big for a surprise like the NES and WS cores were. It'll probably even span multiple v10x releases before it's even ready.

Update to v099r12 release. byuu says: Changelog: - fixed FC AxROM / VRC7 regression - BitField split to BooleanBitField/NaturalBitField (in preparation for IntegerBitField) - BitFieldReference removed - GB CPU cleaned up - GB Cartridge + Mappers cleaned up - SFC CGRAM is now emulated as uint15[256] instead of uint[512] - sfc/ppu/memory.cpp no longer needed; removed - purged SFC Debugger hooks for now (some of the operator[] calls were bypassing them anyway) Unfortunately, for reasons that defy all semblance of logic, the CGRAM change caused a slight speed hit. As have the last few changes. We're now down to around 129.5fps compared to 123.fps for v099 and 134.5fps at our peak (v099r01-r02). I really like the style I came up with for the Game Boy mappers to settle the purpose(ROM,RAM) vs (rom,ram)Purpose naming convention. If I ever get around to redoing the NES mappers, that's likely the approach I'll take.

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.
