Update to v104 public release.
[As mentioned in the v104 internal release notes, byuu fixed a small typo in the GBA core. -Ed.] byuu says: There are lots of improvements in this new release, both to core emulation and to the user interface. However, some of these changes are quite substantial, so regressions are a possibility. Please report any regressions from v103 on the forums if found. Note that Mega Drive save RAM files will not be compatible with v103, but will now be compatible with save RAM files from all other Mega Drive emulators, and the format will be stable going forward. Also!! Thanks to the tireless work of Screwtape, the Help->Documentation link in higan now takes you to a very comprehensive user guide. Please be sure to consult this if you have any questions about using higan. Lastly, I've added a link to my Patreon page (https://patreon.com/byuu/) to the higan downloads page. The money will go exclusively toward purchasing SNES games for preservation, hardware and flash carts for reverse engineering, equipment such as backup drives, etc. Donating is entirely optional and comes with no rewards, but would of course be greatly appreciated! ^^; Changelog (since v103): - nall/dsp: improved first-order IIR filtering - Famicom: improved audio filtering (90hz lowpass + 440hz lowpass + 14khz highpass) - Game Boy Advance: corrected bug in PSG wave channel emulation [Cydrak] - Mega Drive: added first-order 2.84KHz low-pass filter to match VA6 model hardware - Mega Drive: lowered PSG volume relative to YM2612 to match VA6 model hardware - Mega Drive: Hblank flag is not always set during Vblank - Mega Drive: fix PAL mode reporting from control port reads - Famicom: improved phase duty cycle emulation (mode 3 is 25% phase inverted;

Update to v104 release.
byuu says: Changelog: - emulator/interface: removed unused Region struct - gba/cpu: optimized CPU::step() as much as I could for a slight speedup¹ - gba/cpu: synchronize the APU better during FIFO updates - higan/md, icarus: add automatic region detection; make it the default option [hex\_usr] - picks NTSC-J if there's more than one match ... eventually, this will be a setting - higan/md, icarus: support all three combinations of SRAM (8-bit low, 8-bit high, 16-bit) - processor/arm7tdmi: fix bug when changing to THUMB mode via MSR [MerryMage] - tomoko: redesigned crash detector to only occur once for all three ruby drivers - this will reduce disk thrashing since the configuration file only needs to be written out one extra time - technically, it's twice ... but we should've always been writing one out on first run in case it crashes then - tomoko: defaulted back to the safest ruby drivers, given the optimal drivers have some stability concerns ¹: minor errata: spotted a typo saying `synchronize(cpu)` when the CPU is stopped, instead of `synchronize(ppu)`. This will be fixed in the v104 official 7zip archives. I'm kind of rushing here but, it's really good timing for me to push out a new official release. The blocking issues are resolved or close to it, and we need lots of testing of the new major changes. I'm going to consider this a semi-stable testing release and leave links to v103 just in case. |

Update to v103r31 release.
byuu says: Changelog: - gba/cpu: slight speedup to CPU::step() - processor/arm7tdmi: fixed about ten bugs, ST018 and GBA games are now playable once again - processor/arm: removed core from codebase - processor/v30mz: code cleanup (renamed functions; updated instruction() for consistency with other cores) It turns out on my much faster system, the new ARM7TDMI core is very slightly slower than the old one (by about 2% or so FPS.) But the CPU::step() improvement basically made it a wash. So yeah, I'm in really serious trouble with how slow my GBA core is now. Sigh. As for higan/processor ... this concludes the first phase of major cleanups and rewrites. There will always be work to do, and I have two more phases in mind. One is that a lot of the instruction disassemblers are very old. One even uses sprintf still. I'd like to modernize them all. Also, the ARM7TDMI core (and the ARM core before it) can't really disassemble because the PC address used for instruction execution is not known prior to calling instruction(), due to pipeline reload fetches that may occur inside of said function. I had a nasty hack for debugging the new core, but I'd like to come up with a clean way to allow tracing the new ARM7TDMI core. Another is that I'd still like to rename a lot of instruction function names in various cores to be more descriptive. I really liked how the LR35902 core came out there, and would like to get that level of detail in with the other cores as well. |

Update to v103r30 release.
byuu says: Changelog: - processor/arm7tdmi: completed implemented - gba/cpu, sfc/coprocessor/armdsp: use arm7tdmi instead of arm - sfc/cpu: experimental fix for newly discovered HDMA emulation issue Notes: The ARM7TDMI core crashes pretty quickly when trying to run GBA games, and I'm certain the same will be the case with the ST018. It was never all that likely I could rewrite 70KiB of code in 20 hours and have it work perfectly on the first try. So, now it's time for lots and lots of debugging. Any help would *really* be appreciated, if anyone were up for comparing the two implementations for regressions =^-^= I often have a really hard time spotting simple typos that I make. Also, the SNES HDMA fix is temporary. I would like it if testers could run through a bunch of games that are known for being tricky with HDMA (or if these aren't known to said tester, any games are fine then.) If we can confirm regressions, then we'll know the fix is either incorrect or incomplete. But if we don't find any, then it's a good sign that we're on the right path. |

Update to v103r27 release.
byuu says: Changelog: - hiro/windows: set dpiAware=false, fixes icarus window sizes relative to higan window sizes - higan, icarus, hiro, ruby: add support for high resolution displays on macOS [ncbncb] - processor/lr35902-legacy: removed - processor/arm7tdmi: new processor core started; intended to one day be a replacement for processor/arm It will probably take several WIPs to get the new ARM core up and running. It's the last processor rewrite. After this, all processor cores will be up to date with all my current programming conventions. |

Update to v103r08 release.
byuu says: Changelog: - emulator: improved aspect correction accuracy by using floating-point calculations - emulator: added videoCrop() function, extended videoSize() to take cropping parameters¹ - tomoko: the overscan masking function will now actually resize the viewport² - gba/cpu: fixed two-cycle delay on triggering DMAs; not running DMAs when the CPU is stopped - md/vdp: center video when overscan is disabled - pce/vce: resize video output from 1140x240 to 1120x240 - tomoko: resize window scaling from 326x240 to 320x240 - tomoko: changed save slot naming and status bar messages to indicate quick states vs managed states - tomoko: added increment/decrement quick state hotkeys - tomoko: save/load quick state hotkeys now save to slots 1-5 instead of always to 0 - tomoko: increased overscan range from 0-16 to 0-24 (in case you want to mask the Master System to 240x192) ¹: the idea here was to decouple raw pixels from overscan masking. Overscan was actually horrifically broken before. The Famicom outputs at 256x240, the Super Famicom at 512x480, and the Mega Drive at 1280x480. Before, a horizontal overscan mask of 8 would not reduce the Super Famicom or Mega Drive by nearly as much as the Famicom. WIth the new videoCrop() function, the internals of pixel size distortions can be handled by each individual core. ²: furthermore, by taking optional cropping information in videoSize(), games can scale even larger into the viewport window. So for example, before the Super Famicom could only scale to 1536x1440. But by cropping the vertical resolution by 6 (228p effectively, still more than NTSC can even show), I can now scale to 1792x1596. And wiht aspect correction, that becomes a perfect 8:7 ratio of 2048x1596, giving me perfectly crisp pixels without linear interpolation being required. Errata: for some reason, when I save a new managed state with the SFC core, the default description is being set to a string of what looks to be hex numbers. I found the cause ... I'll fix this in the next release. Note: I'd also like to hide the "find codes..." button if cheats.bml isn't present, as well as update the SMP TEST register comment from smp/timing.cpp |

Update to v103r07 release.
byuu says: Changelog: - gba/cpu: massive code cleanup effort - gba/cpu: DMA can run in between active instructions¹ - gba/cpu: added two-cycle startup delay between DMA activation and DMA transfers² - processor/spc700: BBC, BBC, CBNE cycle 4 is an idle cycle - processor/spc700: ADDW, SUBW, MOVW (read) cycle 4 is an idle cycle ¹: unfortunately, this causes yet another performance penalty for the poor GBA core =( Also, I think I may have missed disabling DMAs while the CPU is stopped. I'll fix that in the next WIP. ²: I put the waiting counter decrement at the wrong place, so this doesn't actually work. Needs to be more like this: auto CPU::step(uint clocks) -> void { for(auto _ : range(clocks)) { for(auto& timer : this->timer) timer.run(); for(auto& dma : this->dma) if(dma.active && dma.waiting) dma.waiting--; context.clock++; } ... auto CPU::DMA::run() -> bool { if(cpu.stopped() || !active || waiting) return false; transfer(); if(irq) cpu.irq.flag |= CPU::Interrupt::DMA0 << id; if(drq && id == 3) cpu.irq.flag |= CPU::Interrupt::Cartridge; return true; } Of course, the real fix will be restructuring how DMA works, so that it's always running in parallel with the CPU instead of this weird design where it tries to run all channels in some kind of loop until no channels are active anymore whenever one channel is activated. Not really sure how to design that yet, however. |

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. |

Update to v102r22 release.
byuu says: Changelog: - higan: Emulator::Interface::videoSize() renamed to videoResolution() - higan: Emulator::Interface::rtcsync() renamed to rtcSynchronize() - higan: added video display rotation support to Video - GBA: substantially improved audio mixing - fixed bug with FIFO 50%/100% volume setting - now properly using SOUNDBIAS amplitude to control output frequencies - reduced quantization noise - corrected relative volumes between PSG and FIFO channels - both PSG and FIFO values cached based on amplitude; resulting in cleaner PCM samples - treating PSG volume=3 as 200% volume instead of 0% volume now (unverified: to match mGBA) - GBA: properly initialize ALL CPU state; including the vital prefetch.wait=1 (fixes Classic NES series games) - GBA: added video rotation with automatic key translation support - PCE: reduced output resolution scalar from 285x242 to 285x240 - the extra two scanlines won't be visible on most TVs; and they make all other cores look worse - this is because all other cores output at 240p or less; so they were all receiving black bars in windowed mode - tomoko: added "Rotate Display" hotkey setting - tomoko: changed hotkey multi-key logic to OR instead of AND - left support for flipping it back inside the core; for those so inclined; by uncommenting one line in input.hpp - tomoko: when choosing Settings→Configuration, it will automatically select the currently loaded system - for instance, if you're playing a Game Gear game, it'll take you to the Game Gear input settings - if no games are loaded, it will take you to the hotkeys panel instead - WS(C): merged "Hardware-Vertical", "Hardware-Horizontal" controls into combined "Hardware" - WS(C): converted rotation support from being inside the core to using Emulator::Video - this lets WS(C) video content scale larger now that it's not bounded by a 224x224 square box - WS(C): added automatic key rotation support - WS(C): removed emulator "Rotate" key (use the general hotkey instead; I recommend F8 for this) - nall: added serializer support for nall::Boolean (boolean) types - although I will probably prefer the usage of uint1 in most cases |

Update to v102r20 release.
byuu says: Changelog: - nall: `#undef OUT` on Windows platform - GBA: add missing CPU prefetch state to serialization (this was breaking serialization in games using ROM prefetch) - GBA: reset all PPU data in the power() function (some things were missing before, causing issues on reset) - GBA: restored horizontal mosaic emulation to the new pixel-based renderer - GBA: fixed tilemap background horizontal flipping (Legend of Spyro - warning screen) - GBA: fixed d8 bits of scroll registers (ATV - Thunder Ridge Racers - menu screen) - SFC: DRAM refresh ticks the ALU MUL/DIV registers five steps forward [reported by kevtris] - SFC: merged dmaCounter and autoJoypadCounter into new shared clockCounter - left stub for old dmaCounter so that I can do some traces to ensure the new code's 100% identical GBA save states would have been broken since whenever I emulated ROM prefetch. I guess not many people are using the GBA core ... |

Update to v101r31 release.
byuu says: Changelog: - converted Emulator::Interface::Bind to Emulator::Platform - temporarily disabled SGB hooks - SMS: emulated Game Gear palette (latching word-write behavior not implemented yet) - SMS: emulated Master System 'Reset' button, Game Gear 'Start' button - SMS: removed reset() functionality, driven by the mappable input now instead - SMS: split interface class in two: one for Master System, one for Game Gear - SMS: emulated Game Gear video cropping to 160x144 - PCE: started on HuC6280 CPU core—so far only registers, NOP instruction has been implemented Errata: - Super Game Boy support is broken and thus disabled - if you switch between Master System and Game Gear without restarting, bad things happen: - SMS→GG, no video output on the GG - GG→SMS, no input on the SMS I'm not sure what's causing the SMS\<-\>GG switch bug, having a hard time debugging it. Help would be very much appreciated, if anyone's up for it. Otherwise I'll keep trying to track it down on my end. |

Update to v101r25 release.
byuu says: Changelog: - Makefile: added $(windres), -lpthread to Windows port - GBA: WAITCNT.prefetch is not writable (should fix Donkey Kong: King of Swing) \[endrift\] - SMS: fixed hcounter shift value \[hex\_usr\] - SMS: emulated interrupts (reset button isn't hooked up anywhere, not sure where to put it yet) This WIP actually took a really long time because the documentation on SMS interrupts was all over the place. I'm hoping I've emulated them correctly, but I honestly have no idea. It's based off my best understanding from four or five different sources. So it's probably quite buggy. However, a few interrupts fire in Sonic the Hedgehog, so that's something to start with. Now I just have to hope I've gotten some games far enough in that I can start seeing some data in the VDP VRAM. I need that before I can start emulating graphics mode 4 to get some actual screen output. Or I can just say to hell with it and use a "Hello World" test ROM. That'd probably be smarter. |

Tim Allen | ca277cd5e8 |
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. |

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 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 v098r06 release.
byuu says: Changelog: - emulation cores now refresh video from host thread instead of cothreads (fix AMD crash) - SFC: fixed another bug with leap year months in SharpRTC emulation - SFC: cleaned up camelCase on function names for armdsp,epsonrtc,hitachidsp,mcc,nss,sharprtc classes - GB: added MBC1M emulation (requires manually setting mapper=MBC1M in manifest.bml for now, sorry) - audio: implemented Emulator::Audio mixer and effects processor - audio: implemented Emulator::Stream interface - it is now possible to have more than two audio streams: eg SNES + SGB + MSU1 + Voicer-Kun (eventually) - audio: added reverb delay + reverb level settings; exposed balance configuration in UI - video: reworked palette generation to re-enable saturation, gamma, luminance adjustments - higan/emulator.cpp is gone since there was nothing left in it I know you guys are going to say the color adjust/balance/reverb stuff is pointless. And indeed it mostly is. But I like the idea of allowing some fun special effects and configurability that isn't system-wide. Note: there seems to be some kind of added audio lag in the SGB emulation now, and I don't really understand why. The code should be effectively identical to what I had before. The only main thing is that I'm sampling things to 48000hz instead of 32040hz before mixing. There's no point where I'm intentionally introducing added latency though. I'm kind of stumped, so if anyone wouldn't mind taking a look at it, it'd be much appreciated :/ I don't have an MSU1 test ROM, but the latency issue may affect MSU1 as well, and that would be very bad. |

Update to v097r17 release.
byuu says: Changelog: - ruby: if DirectSoundCreate fails (no sound device present), return false from init instead of crashing - nall: improved edge case return values for (basename,pathname,dirname,...) - nall: renamed file_system_object class to inode - nall: varuint_t replaced with VariadicNatural; which contains .bit,.bits,.byte ala Natural/Integer - nall: fixed boolean compilation error on Windows - WS: popa should not restore SP - GBA: rewrote the CPU/APU cores to use the .bit,.bits functions; removed registers.cpp from each Note that the GBA changes are extremely major. This is about five hours worth of extremely delicate work. Any slight errors could break emulation in extremely bad ways. Let's hold off on extensive testing until the next WIP, after I do the same to the PPU. So far ... endrift's SOUNDCNT_X I/O test is failing, although that code didn't change, so clearly I messed up SOUNDCNT_H somehow ... To compile on Windows: 1. change nall/string/platform.hpp line 47 to return slice(result, 0, 3); 2. change ruby/video.wgl.cpp line 72 to auto lock(uint32_t*& data, uint& pitch, uint width, uint height) -> bool { 3. add this line to the very top of hiro/windows/header.cpp: #define boolean FuckYouMicrosoft |

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 20160215 release.
byuu says: Got it. Wow, that didn't hurt nearly as much as I thought it was going to. Dropped from 127.5fps to 123.5fps to use Natural/Integer for (u)int(8,16,32,64). That's totally worth the cost. |

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 v096r01 release.
byuu says: Changelog: - restructured the project and removed a whole bunch of old/dead directives from higan/GNUmakefile - huge amounts of work on hiro/cocoa (compiles but ~70% of the functionality is commented out) - fixed a masking error in my ARM CPU disassembler [Lioncash] - SFC: decided to change board cic=(411,413) back to board region=(ntsc,pal) ... the former was too obtuse If you rename Boolean (it's a problem with an include from ruby, not from hiro) and disable all the ruby drivers, you can compile an OS X binary, but obviously it's not going to do anything. It's a boring WIP, I just wanted to push out the project structure change now at the start of this WIP cycle. |

Update to v093 release.
byuu says: Changelog: - added Cocoa target: higan can now be compiled for OS X Lion [Cydrak, byuu] - SNES/accuracy profile hires color blending improvements - fixes Marvelous text [AWJ] - fixed a slight bug in SNES/SA-1 VBR support caused by a typo - added support for multi-pass shaders that can load external textures (requires OpenGL 3.2+) - added game library path (used by ananke->Import Game) to Settings->Advanced - system profiles, shaders and cheats database can be stored in "all users" shared folders now (eg /usr/share on Linux) - all configuration files are in BML format now, instead of XML (much easier to read and edit this way) - main window supports drag-and-drop of game folders (but not game files / ZIP archives) - audio buffer clears when entering a modal loop on Windows (prevents audio repetition with DirectSound driver) - a substantial amount of code clean-up (probably the biggest refactoring to date) One highly desired target for this release was to default to the optimal drivers instead of the safest drivers, but because AMD drivers don't seem to like my OpenGL 3.2 driver, I've decided to postpone that. AMD has too big a market share. Hopefully with v093 officially released, we can get some public input on what AMD doesn't like. |

Update to v092r09 release.
byuu says: This will be another massive diff from the previous version. 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. |

Update to higan v091 release.
byuu says: Basically just a project rename, with s/bsnes/higan and the new icon from lowkee added in. It won't compile on Windows because I forgot to update the resource.rc file, and a path transform command isn't working on Windows. It was really just meant as a starting point, so that v091 WIPs can flow starting from .00 with the new name (it overshadows bsnes v091, so publicly speaking this "shouldn't exist" and will probably be deleted from Google Code when v092 is ready.) |
