Update to v100r15 release.
byuu wrote: Aforementioned scheduler changes added. Longer explanation of why here: http://hastebin.com/raw/toxedenece Again, we really need to test this as thoroughly as possible for regressions :/ This is a really major change that affects absolutely everything: all emulation cores, all coprocessors, etc. Also added ADDX and SUB to the 68K core, which brings us just barely above 50% of the instruction encoding space completed. [Editor's note: The "aformentioned scheduler changes" were described in a previous forum post: Unfortunately, 64-bits just wasn't enough precision (we were getting misalignments ~230 times a second on 21/24MHz clocks), so I had to move to 128-bit counters. This of course doesn't exist on 32-bit architectures (and probably not on all 64-bit ones either), so for now ... higan's only going to compile on 64-bit machines until we figure something out. Maybe we offer a "lower precision" fallback for machines that lack uint128_t or something. Using the booth algorithm would be way too slow. Anyway, the precision is now 2^-96, which is roughly 10^-29. That puts us far beyond the yoctosecond. Suck it, MAME :P I'm jokingly referring to it as the byuusecond. The other 32-bits of precision allows a 1Hz clock to run up to one full second before all clocks need to be normalized to prevent overflow. I fixed a serious wobbling issue where I was using clock > other.clock for synchronization instead of clock >= other.clock; and also another aliasing issue when two threads share a common frequency, but don't run in lock-step. The latter I don't even fully understand, but I did observe it in testing. nall/serialization.hpp has been extended to support 128-bit integers, but without explicitly naming them (yay generic code), so nall will still compile on 32-bit platforms for all other applications. Speed is basically a wash now. FC's a bit slower, SFC's a bit faster. The "longer explanation" in the linked hastebin is: Okay, so the idea is that we can have an arbitrary number of oscillators. Take the SNES: - CPU/PPU clock = 21477272.727272hz - SMP/DSP clock = 24576000hz - Cartridge DSP1 clock = 8000000hz - Cartridge MSU1 clock = 44100hz - Controller Port 1 modem controller clock = 57600hz - Controller Port 2 barcode battler clock = 115200hz - Expansion Port exercise bike clock = 192000hz Is this a pathological case? Of course it is, but it's possible. The first four do exist in the wild already: see Rockman X2 MSU1 patch. Manifest files with higan let you specify any frequency you want for any component. The old trick higan used was to hold an int64 counter for each thread:thread synchronization, and adjust it like so: - if thread A steps X clocks; then clock += X * threadB.frequency - if clock >= 0; switch to threadB - if thread B steps X clocks; then clock -= X * threadA.frequency - if clock < 0; switch to threadA But there are also system configurations where one processor has to synchronize with more than one other processor. Take the Genesis: - the 68K has to sync with the Z80 and PSG and YM2612 and VDP - the Z80 has to sync with the 68K and PSG and YM2612 - the PSG has to sync with the 68K and Z80 and YM2612 Now I could do this by having an int64 clock value for every association. But these clock values would have to be outside the individual Thread class objects, and we would have to update every relationship's clock value. So the 68K would have to update the Z80, PSG, YM2612 and VDP clocks. That's four expensive 64-bit multiply-adds per clock step event instead of one. As such, we have to account for both possibilities. The only way to do this is with a single time base. We do this like so: - setup: scalar = timeBase / frequency - step: clock += scalar * clocks Once per second, we look at every thread, find the smallest clock value. Then subtract that value from all threads. This prevents the clock counters from overflowing. Unfortunately, these oscillator values are psychotic, unpredictable, and often times repeating fractions. Even with a timeBase of 1,000,000,000,000,000,000 (one attosecond); we get rounding errors every ~16,300 synchronizations. Specifically, this happens with a CPU running at 21477273hz (rounded) and SMP running at 24576000hz. That may be good enough for most emulators, but ... you know how I am. Plus, even at the attosecond level, we're really pushing against the limits of 64-bit integers. Given the reciprocal inverse, a frequency of 1Hz (which does exist in higan!) would have a scalar that consumes 1/18th of the entire range of a uint64 on every single step. Yes, I could raise the frequency, and then step by that amount, I know. But I don't want to have weird gotchas like that in the scheduler core. Until I increase the accuracy to about 100 times greater than a yoctosecond, the rounding errors are too great. And since the only choice above 64-bit values is 128-bit values; we might as well use all the extra headroom. 2^-96 as a timebase gives me the ability to have both a 1Hz and 4GHz clock; and run them both for a full second; before an overflow event would occur. Another hastebin includes demonstration code: #include <libco/libco.h> #include <nall/nall.hpp> using namespace nall; // cothread_t mainThread = nullptr; const uint iterations = 100'000'000; const uint cpuFreq = 21477272.727272 + 0.5; const uint smpFreq = 24576000.000000 + 0.5; const uint cpuStep = 4; const uint smpStep = 5; // struct ThreadA { cothread_t handle = nullptr; uint64 frequency = 0; int64 clock = 0; auto create(auto (*entrypoint)() -> void, uint frequency) { this->handle = co_create(65536, entrypoint); this->frequency = frequency; this->clock = 0; } }; struct CPUA : ThreadA { static auto Enter() -> void; auto main() -> void; CPUA() { create(&CPUA::Enter, cpuFreq); } } cpuA; struct SMPA : ThreadA { static auto Enter() -> void; auto main() -> void; SMPA() { create(&SMPA::Enter, smpFreq); } } smpA; uint8 queueA[iterations]; uint offsetA; cothread_t resumeA = cpuA.handle; auto EnterA() -> void { offsetA = 0; co_switch(resumeA); } auto QueueA(uint value) -> void { queueA[offsetA++] = value; if(offsetA >= iterations) { resumeA = co_active(); co_switch(mainThread); } } auto CPUA::Enter() -> void { while(true) cpuA.main(); } auto CPUA::main() -> void { QueueA(1); smpA.clock -= cpuStep * smpA.frequency; if(smpA.clock < 0) co_switch(smpA.handle); } auto SMPA::Enter() -> void { while(true) smpA.main(); } auto SMPA::main() -> void { QueueA(2); smpA.clock += smpStep * cpuA.frequency; if(smpA.clock >= 0) co_switch(cpuA.handle); } // struct ThreadB { cothread_t handle = nullptr; uint128_t scalar = 0; uint128_t clock = 0; auto print128(uint128_t value) { string s; while(value) { s.append((char)('0' + value % 10)); value /= 10; } s.reverse(); print(s, "\n"); } //femtosecond (10^15) = 16306 //attosecond (10^18) = 688838 //zeptosecond (10^21) = 13712691 //yoctosecond (10^24) = 13712691 (hitting a dead-end on a rounding error causing a wobble) //byuusecond?

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 v100r07 release.
byuu says: Four and a half hours of work and ... zero new opcodes implemented. This was the best job I could do refining the effective address computations. Should have all twelve 68000 modes implemented now. Still have a billion questions about when and how I'm supposed to perform certain edge case operations, though. |

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 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 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 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 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 v098r01 release.
byuu says:
Changelog:
- SFC: balanced profile removed
- SFC: performance profile removed
- SFC: code for handling non-threaded CPU, SMP, DSP, PPU removed
- SFC: Coprocessor, Controller (and expansion port) shared Thread code
merged to SFC::Cothread
- Cothread here just means "Thread with CPU affinity" (couldn't think
of a better name, sorry)
- SFC: CPU now has vector<Thread*> coprocessors, peripherals;
- this is the beginning of work to allow expansion port devices to be
dynamically changed at run-time
- ruby: all audio drivers default to 48000hz instead of 22050hz now if
no frequency is assigned
- note: the WASAPI driver can default to whatever the native frequency
is; doesn't have to be 48000hz
- tomoko: removed the ability to change the frequency from the UI (but
it will display the frequency used)
- tomoko: removed the timing settings panel
- the goal is to work toward smooth video via adaptive sync
- the model is broken by not being in control of the audio frequency
anyway
- it's further broken by PAL running at 50hz and WSC running at 75hz
- it was always broken anyway by SNES interlace timing varying from
progressive timing
- higan: audio/ stub created (for now, it's just nall/dsp/ moved here
and included as a header)
- higan: video/ stub created
- higan/GNUmakefile: now includes build rules for essential components
(libco, emulator, audio, video)
The audio changes are in preparation to merge wareya's awesome WASAPI
work without the need for the nall/dsp resampler.

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 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 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. |

It's a boring WIP, I just wanted to push out the project structure change now at the start of this WIP cycle. |
