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 v098r16 release. byuu says: Changelog: - GNUmakefile: reverted $(call unique,) to $(strip) - processor/r6502: removed templates; reduces object size from 146.5kb to 107.6kb - processor/lr35902: removed templates; reduces object size from 386.2kb to 197.4kb - processor/spc700: merged op macros for switch table declarations - sfc/coprocessor/sa1: partial cleanups; flattened directory structure - sfc/coprocessor/superfx: partial cleanups; flattened directory structure - sfc/coprocessor/icd2: flattened directory structure - gb/ppu: changed behavior of STAT IRQs Major caveat! The GB/GBC STAT IRQ changes has a major bug in it somewhere that's seriously breaking most games. I'm pushing the WIP anyway, because I believe the changes to be mostly correct. I'd like to get more people looking at these changes, and also try more heavy-handed hacking and diff comparison logging between the previous WIP and this one.

Update to v099r13 release. byuu says: Changelog: - GB core code cleanup completed - GBA core code cleanup completed - some more cleanup on missed processor/arm functions/variables - fixed FC loading icarus bug - "Load ROM File" icarus functionality restored - minor code unification efforts all around (not perfect yet) - MMIO->IO - mmio.cpp->io.cpp - read,write->readIO,writeIO It's been a very long work in progress ... starting all the way back with v094r09, but the major part of the higan code cleanup is now completed! Of course, it's very important to note that this is only for the basic style: - under_score functions and variables are now camelCase - return-type function-name() are now auto function-name() -> return-type - Natural<T>/Integer<T> replace (u)intT_n types where possible - signed/unsigned are now int/uint - most of the x==true,x==false tests changed to x,!x A lot of spot improvements to consistency, simplicity and quality have gone in along the way, of course. But we'll probably never fully finishing beautifying every last line of code in the entire codebase. Still, this is a really great start. Going forward, WIP diffs should start being smaller and of higher quality once again. I know the joke is, "until my coding style changes again", but ... this was way too stressful, way too time consuming, and way too risky. I'm too old and tired now for extreme upheavel like this again. The only major change I'm slowly mulling over would be renaming the using Natural<T>/Integer<T> = (u)intT; shorthand to something that isn't as easily confused with the (u)int_t types ... but we'll see. I'll definitely continue to change small things all the time, but for the larger picture, I need to just accept the style I have and live with it.

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 v100r14 release. byuu says: (Windows: compile with -fpermissive to silence an annoying error. I'll fix it in the next WIP.) I completely replaced the time management system in higan and overhauled the scheduler. Before, processor threads would have "int64 clock"; and there would be a 1:1 relationship between two threads. When thread A ran for X cycles, it'd subtract X * B.Frequency from clock; and when thread B ran for Y cycles, it'd add Y * A.Frequency from clock. This worked well and allowed perfect precision; but it doesn't work when you have more complicated relationships: eg the 68K can sync to the Z80 and PSG; the Z80 to the 68K and PSG; so the PSG needs two counters. The new system instead uses a "uint64 clock" variable that represents time in attoseconds. Every time the scheduler exits, it subtracts the smallest clock count from all threads, to prevent an overflow scenario. The only real downside is that rounding errors mean that roughly every 20 minutes, we have a rounding error of one clock cycle (one 20,000,000th of a second.) However, this only applies to systems with multiple oscillators, like the SNES. And when you're in that situation ... there's no such thing as a perfect oscillator anyway. A real SNES will be thousands of times less out of spec than 1hz per 20 minutes. The advantages are pretty immense. First, we obviously can now support more complex relationships between threads. Second, we can build a much more abstracted scheduler. All of libco is now abstracted away completely, which may permit a state-machine / coroutine version of Thread in the future. We've basically gone from this: auto SMP::step(uint clocks) -> void { clock += clocks * (uint64)cpu.frequency; dsp.clock -= clocks; if(dsp.clock < 0 && !scheduler.synchronizing()) co_switch(dsp.thread); if(clock >= 0 && !scheduler.synchronizing()) co_switch(cpu.thread); } To this: auto SMP::step(uint clocks) -> void { Thread::step(clocks); synchronize(dsp); synchronize(cpu); } As you can see, we don't have to do multiple clock adjustments anymore. This is a huge win for the SNES CPU that had to update the SMP, DSP, all peripherals and all coprocessors. Likewise, we don't have to synchronize all coprocessors when one runs, now we can just synchronize the active one to the CPU. Third, when changing the frequencies of threads (think SGB speed setting modes, GBC double-speed mode, etc), it no longer causes the "int64 clock" value to be erroneous. Fourth, this results in a fairly decent speedup, mostly across the board. Aside from the GBA being mostly a wash (for unknown reasons), it's about an 8% - 12% speedup in every other emulation core. Now, all of this said ... this was an unbelievably massive change, so ... you know what that means >_> If anyone can help test all types of SNES coprocessors, and some other system games, it'd be appreciated. ---- Lastly, we have a bitchin' new about screen. It unfortunately adds ~200KiB onto the binary size, because the PNG->C++ header file transformation doesn't compress very well, and I want to keep the original resource files in with the higan archive. I might try some things to work around this file size increase in the future, but for now ... yeah, slightly larger archive sizes, sorry. The logo's a bit busted on Windows (the Label control's background transparency and alignment settings aren't working), but works well on GTK. I'll have to fix Windows before the next official release. For now, look on my Twitter feed if you want to see what it's supposed to look like. ---- EDIT: forgot about ICD2::Enter. It's doing some weird inverse run-to-save thing that I need to implement support for somehow. So, save states on the SGB core probably won't work 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.

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.

step(2);
Update to v100r14 release. byuu says: (Windows: compile with -fpermissive to silence an annoying error. I'll fix it in the next WIP.) I completely replaced the time management system in higan and overhauled the scheduler. Before, processor threads would have "int64 clock"; and there would be a 1:1 relationship between two threads. When thread A ran for X cycles, it'd subtract X * B.Frequency from clock; and when thread B ran for Y cycles, it'd add Y * A.Frequency from clock. This worked well and allowed perfect precision; but it doesn't work when you have more complicated relationships: eg the 68K can sync to the Z80 and PSG; the Z80 to the 68K and PSG; so the PSG needs two counters. The new system instead uses a "uint64 clock" variable that represents time in attoseconds. Every time the scheduler exits, it subtracts the smallest clock count from all threads, to prevent an overflow scenario. The only real downside is that rounding errors mean that roughly every 20 minutes, we have a rounding error of one clock cycle (one 20,000,000th of a second.) However, this only applies to systems with multiple oscillators, like the SNES. And when you're in that situation ... there's no such thing as a perfect oscillator anyway. A real SNES will be thousands of times less out of spec than 1hz per 20 minutes. The advantages are pretty immense. First, we obviously can now support more complex relationships between threads. Second, we can build a much more abstracted scheduler. All of libco is now abstracted away completely, which may permit a state-machine / coroutine version of Thread in the future. We've basically gone from this: auto SMP::step(uint clocks) -> void { clock += clocks * (uint64)cpu.frequency; dsp.clock -= clocks; if(dsp.clock < 0 && !scheduler.synchronizing()) co_switch(dsp.thread); if(clock >= 0 && !scheduler.synchronizing()) co_switch(cpu.thread); } To this: auto SMP::step(uint clocks) -> void { Thread::step(clocks); synchronize(dsp); synchronize(cpu); } As you can see, we don't have to do multiple clock adjustments anymore. This is a huge win for the SNES CPU that had to update the SMP, DSP, all peripherals and all coprocessors. Likewise, we don't have to synchronize all coprocessors when one runs, now we can just synchronize the active one to the CPU. Third, when changing the frequencies of threads (think SGB speed setting modes, GBC double-speed mode, etc), it no longer causes the "int64 clock" value to be erroneous. Fourth, this results in a fairly decent speedup, mostly across the board. Aside from the GBA being mostly a wash (for unknown reasons), it's about an 8% - 12% speedup in every other emulation core. Now, all of this said ... this was an unbelievably massive change, so ... you know what that means >_> If anyone can help test all types of SNES coprocessors, and some other system games, it'd be appreciated. ---- Lastly, we have a bitchin' new about screen. It unfortunately adds ~200KiB onto the binary size, because the PNG->C++ header file transformation doesn't compress very well, and I want to keep the original resource files in with the higan archive. I might try some things to work around this file size increase in the future, but for now ... yeah, slightly larger archive sizes, sorry. The logo's a bit busted on Windows (the Label control's background transparency and alignment settings aren't working), but works well on GTK. I'll have to fix Windows before the next official release. For now, look on my Twitter feed if you want to see what it's supposed to look like. ---- EDIT: forgot about ICD2::Enter. It's doing some weird inverse run-to-save thing that I need to implement support for somehow. So, save states on the SGB core probably won't work with this WIP.

All of higan was updated to use the new foo& bar syntax, and I also updated switch statements to be consistent as well (but not in the disassemblers, was starting to get an RSI just from what I already did.) phoenix/{windows, cocoa, qt} need to be updated to use "string foo" instead of "const string& foo", and after that, the major diffs should be finished. This archive is the first time I'm posting my copy-on-write, size+capacity nall::string class, so any feedback on that is welcome as well.

Not sure what the hell is going on there. Trace logs of 430MB are not enticing ... So right now: SuperFX, SPC7110 and BS-X cheat by mapping stuff to Cartridge::ROM, RAM still. They need to not do that.

Update to v095r06 release. byuu says: Changelog: - fixed I/O register reads; perfect score on endrift's I/O tests now - fixed mouse capture clipping on Windows [Cydrak] - several hours of code maintenance work done on the SFC core All higan/sfc files should now use the auto fn() -> ret; syntax. Haven't converted all unsigned->uint yet. Also, probably won't do sfc/alt as that's mostly just speed hack stuff. Errata: - forgot auto& instead of just auto on SuperFamicom::Video::draw_cursor, which makes Super Scope / Justifier crash. Will be fixed in the next WIP.

auto SA1::power() -> void {
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 v074r11 release. byuu says: Changelog: - debugger compiles on all three profiles - libsnes compiles on all three platforms (no API changes to libsnes) - memory.cpp : namespace memory removed (wram -> cpu, apuram -> smp, vram, oam, cgram -> ppu) - sa1.cpp : namespace memory removed (SA-1 specific functions merged inline to SA1::bus_read,write) - GameBoy: added serial link support with interrupts and proper 8192hz timing, but obviously it acts as if no other GB is connected to it - GameBoy: added STAT OAM interrupt, and better STAT d1,d0 mode values - UI: since Qt is dead, I've renamed the config files back to bsnes.cfg and bsnes-geometry.cfg - SA1: IRAM was not syncing to CPU on SA-1 side - PPU/Accuracy and PPU/Performance needed Sprite oam renamed to Sprite sprite; so that I could add uint8 oam[544] - makes more sense anyway, OAM = object attribute memory, obj or sprite are better names for Sprite rendering class - more cleanup
