Update to v100r16 release.
byuu says: (Windows users may need to include <sys/time.h> at the top of nall/chrono.hpp, not sure.) Unchangelog: - forgot to add the Scheduler clock=0 fix because I have the memory of a goldfish Changelog: - new icarus database with nine additional games - hiro(GTK,Qt) won't constantly write its settings.bml file to disk anymore - added latency simulator for fun (settings.bml => Input/Latency in milliseconds) So the last one ... I wanted to test out nall::chrono, and I was also thinking that by polling every emulated frame, it's pretty wasteful when you are using Fast Forward and hitting 200+fps. As I've said before, calls to ruby::input::poll are not cheap. So to get around this, I added a limiter so that if you called the hardware poll function within N milliseconds, it'll return without doing any actual work. And indeed, that increases my framerate of Zelda 3 uncapped from 133fps to 142fps. Yay. But it's not a "real" speedup, as it only helps you when you exceed 100% speed (theoretically, you'd need to crack 300% speed since the game itself will poll at 16ms at 100% speed, but yet it sped up Zelda 3, so who am I to complain?) I threw the latency value into the settings file. It should be 16, but I set it to 5 since that was the lowest before it started negatively impacting uncapped speeds. You're wasting your time and CPU cycles setting it lower than 5, but if people like placebo effects it might work. Maybe I should let it be a signed integer so people can set it to -16 and think it's actually faster :P (I'm only joking. I took out the 96000hz audio placebo effect as well. Not really into psychological tricks anymore.) But yeah seriously, I didn't do this to start this discussion again for the billionth time. Please don't go there. And please don't tell me this WIP has higher/lower latency than before. I don't want to hear it. The only reason I bring it up is for the fun part that is worth discussing: put up or shut up time on how sensitive you are to latency! You can set the value above 5 to see how games feel. I personally can't really tell a difference until about 50. And I can't be 100% confident it's worse until about 75. But ... when I set it to 150, games become "extra difficult" ... the higher it goes, the worse it gets :D For this WIP, I've left no upper limit cap. I'll probably set a cap of something like 500ms or 1000ms for the official release. Need to balance user error/trolling with enjoyability. I'll think about it. [...] Now, what I worry about is stupid people seeing it and thinking it's an "added latency" setting, as if anyone would intentionally make things worse by default. This is a limiter. So if 5ms have passed since the game last polled, and that will be the case 99.9% of the time in games, the next poll will happen just in time, immediately when the game polls the inputs. Thus, a value below 1/<framerate>ms is not only pointless, if you go too low it will ruin your fast forward max speeds. I did say I didn't want to resort to placebo tricks, but I also don't want to spark up public discussion on this again either. So it might be best to default Input/Latency to 0ms, and internally have a max(5, latency) wrapper around the value. |

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 v099r15 release.
byuu says:
Changelog:
- nall::lstring -> nall::string_vector
- added IntegerBitField<type, lo, hi> -- hopefully it works correctly...
- Multitap 1-4 -> Super Multitap 2-5
- fixed SFC PPU CGRAM read regression
- huge amounts of SFC PPU IO register cleanups -- .bits really is lovely
- re-added the read/write(VRAM,OAM,CGRAM) helpers for the SFC PPU
- but they're now optimized to the realities of the PPU (16-bit data
sizes / no address parameter / where appropriate)
- basically used to get the active-display overrides in a unified place;
but also reduces duplicate code in (read,write)IO

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 v099r10 release.
byuu says:
Changelog:
- higan/profile/ => higan/systems/ [temporary; unless we can't think of
a better base folder name]
- god-damn-better-have fixed the input polling bug
- re-added command-line and drag-and-drop loading
- command-line loading can now load multiple folders at once (SGB+GB
game; Sufami Turbo+Slot A+Slot B; etc)
- if you load just the base cart, it'll present you with a dialog to
optionally load slotted cart(s)
- MSU1 now goes through nall/vfs instead of directly accessing the
filesystem
- Famicom Cartridge, PPU cores updated to newer programming style
- there's countless opportunity for BitField and .bits() in the PPU
... but I'm worried about breaking things
If anyone has a working MSU1 game and can test the changes out, that'd
be appreciated. I still don't have a test ROM on my dev box.
I wouldn't worry too much about extensively testing the Famicom PPU
changes just yet ... I'm still struggling with what to name the structs
inside the classes between all of my emulators, and the BitField/.bits()
changes will be much more important to test at a later date.
The only use case left for Emulator::Interface::path(uint id) is for
21fx emulation. This peripheral loads a DLL/SO via LoadLibrary/dlopen,
which do not have any official ways to open a file in RAM. I'm
very hesitant to use the portable trick of writing the memory to a
temporary file, loading it, and deleting the temporary file once done
... it's a real waste of disk activity. I might make something like
vfs::file::isVirtual->bool,path()->string to get around this. But even
once I do, the underlying LoadLibrary/dlopen call is still going to be
direct disk access.

Update to v099r08 release.
byuu says:
Changelog:
- nall/vfs work 100% completed; even SGB games load now
- emulation cores now call load() for the base cartridges as well
- updated port/device handling; portmask is gone; device ID bug should
be resolved now
- SNES controller port 1 multitap option was removed
- added support for 128KiB SNES PPU VRAM (for now, edit sfc/ppu/ppu.hpp
VRAM::size=0x10000; to enable)
Overall, nall/vfs was a huge success!! We've substantially reduced
the amount of boilerplate code everywhere, while still allowing (even
easier than before) support for RAM-based game loading/saving. All of
nall/stream is dead and buried.
I am considering removing Emulator::Interface::Medium::id and/or
bootable flag. Or at least, doing something different with it. The
values for the non-bootable GB/BS/ST entries duplicate the ID that is
supposed to be unique. They are for GB/GBC and WS/WSC. Maybe I'll use
this as the hardware revision selection ID, and then gut non-bootable
options. There's really no reason for that to be there. I think at one
point I was using it to generate library tabs for non-bootable systems,
but we don't do that anymore anyway.
Emulator::Interface::load() may not need the required flag anymore ... it
doesn't really do anything right now anyway.
I have a few reasons for having the cores load the base cartridge. Most
importantly, it is going to enable a special mode for the WonderSwan /
WonderSwan Color in the future. If we ever get the IPLROMs dumped ... it's
possible to boot these systems with no games inserted to set user profile
information and such. There are also other systems that may accept being
booted without a cartridge. To reach this state, you would load a game and
then cancel the load dialog. Right now, this results in games not loading.
The second reason is this prevents nasty crashes when loading fails. So
if you're missing a required manifest, the emulator won't die a violent
death anymore. It's able to back out at any point.
The third reason is consistency: loading the base cartridge works the
same as the slot cartridges.
The fourth reason is Emulator::Interface::open(uint pathID)
values. Before, the GB, SB, GBC modes were IDs 1,2,3 respectively. This
complicated things because you had to pass the correct ID. But now
instead, Emulator::Interface::load() returns maybe<uint> that is nothing
when no game is selected, and a pathID for a valid game. And now open()
can take this ID to access this game's folder contents.
The downside, which is temporary, is that command-line loading is
currently broken. But I do intend on restoring it. In fact, I want to do
better than before and allow multi-cart booting from the command-line by
specifying the base cartridge and then slot cartridges. The idea should
be pretty simple: keep a queue of pending filenames that we fill from
the command-line and/or drag-and-drop operations on the main window,
and then empty out the queue or prompt for load dialogs from the UI
when booting a system. This also might be a bit more unorthodox compared
to the traditional emulator design of "loadGame(filename)", but ... oh
well. It's easy enough still.
The port/device changes are fun. We simplified things quite a bit. The
portmask stuff is gone entirely. While ports and devices keep IDs,
this is really just sugar-coating so UIs can use for(auto& port :
emulator->ports) and access port.id; rather than having to use for(auto
n : range(emulator->ports)) { auto& port = emulator->ports[n]; ... };
but they should otherwise generally be identical to the order they appear
in their respective ranges. Still, don't rely on that.
Input::id is gone. There was no point since we also got rid of the nasty
Input::order vector. Since I was in here, I went ahead and caved on the
pedantics and renamed Input::guid to Input::userData.
I removed the SNES controller port 1 multitap option. Basically, the only
game that uses this is N-warp Daisakusen and, no offense to d4s, it's
not really a good game anyway. It's just a quick demo to show 8-players
on the SNES. But in the UI, all it does is confuse people into wasting
time mapping a controller they're never going to use, and they're going
to wonder which port to use. If more compelling use cases for 8-players
comes about, we can reconsider this. I left all the code to support this
in place, so all you have to do is uncomment one line to enable it again.
We now have dsnes emulation! :D
If you change PPU::VRAM::size to 0x10000 (words), then you should now
have 128KiB of VRAM. Even better, it serializes the used-VRAM size,
so your save states shouldn't crash on you if you swap between the two
(though if you try this, you're nuts.)
Note that this option does break commercial software. Yoshi's Island in
particular. This game is setting A15 on some PPU register writes, but
not on others. The end result of this is things break horribly in-game.
Also, this option is causing a very tiny speed hit for obvious reasons
with the variable masking value (I'm even using size-1 for now.) Given
how niche this is, I may just leave it a compile-time constant to avoid
the overhead cost. Otherwise, if we keep the option, then it'll go into
Super Famicom.sys/manifest.bml ... I'll flesh that out in the near-future.
----
Finally, some fun for my OCD ... my monitor suddenly cut out on me
in the middle of working on this WIP, about six hours in of non-stop
work. Had to hit a bunch of ctrl+alt+fN commands (among other things)
and trying to log in headless on another TTY to do issue commands,
trying to recover the display. Finally power cycled the monitor and it
came back up. So all my typing ended up going to who knows where.
Usually this sort of thing terrifies me enough that I scrap a WIP and
start over to ensure I didn't screw anything up during the crashed screen
when hitting keys randomly.
Obviously, everything compiles and appears to work fine. And I know
it's extremely paranoid, but OCD isn't logical, so ... I'm going
to go over every line of the 100KiB r07->r08 diff looking for any
corruption/errors/whatever.
----
Review finished.
r08 diff review notes:
- fc/controller/gamepad/gamepad.cpp:
use uint device = ID::Device::Gamepad; not id = ...;
- gb/cartridge/cartridge.hpp:
remove redundant uint _pathID; (in Information::pathID already)
- gb/cartridge/cartridge.hpp:
pull sha256 inside Information
- sfc/cartridge/load/cpp:
add " - Slot (A,B)" to interface->load("Sufami Turbo"); to be more
descriptive
- sfc/controller/gamepad/gamepad.cpp:
use uint device = ID::Device::Gamepad; not id = ...;
- sfc/interface/interface.cpp:
remove n variable from the Multitap device input generation loop
(now unused)
- sfc/interface/interface.hpp:
put struct Port above struct Device like the other classes
- ui-tomoko:
cheats.bml is reading from/writing to mediumPaths(0) [system folder
instead of game folder]
- ui-tomoko:
instead of mediumPaths(1) - call emulator->metadataPathID() or something
like that

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.

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.

- 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

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.

Update to v097r12 release.
byuu says: Nothing WS-related this time. First, I fixed expansion port device mapping. On first load, it was mapping the expansion port device too late, so it ended up not taking effect. I had to spin out the logic for that into Program::connectDevices(). This was proving to be quite annoying while testing eBoot (SNES-Hook simulation.) Second, I fixed the audio->set(Frequency, Latency) functions to take (uint) parameters from the configuration file, so the weird behavior around changing settings in the audio panel should hopefully be gone now. Third, I rewrote the interface->load,unload functions to call into the (Emulator)::System::load,unload functions. And I have those call out to Cartridge::load,unload. Before, this was inverted, and Cartridge::load() was invoking System::load(), which I felt was kind of backward. The Super Game Boy really didn't like this change, however. And it took me a few hours to power through it. Before, I had the Game Boy core dummying out all the interface->(load,save)Request calls, and having the SNES core make them for it. This is because the folder paths and IDs will be different between the two cores. I've redesigned things so that ICD2's Emulator::Interface overloads loadRequest and saveRequest, and translates the requests into new requests for the SuperFamicom core. This allows the Game Boy code to do its own loading for everything without a bunch of Super Game Boy special casing, and without any awkwardness around powering on with no cartridge inserted. This also lets the SNES side of things simply call into higher-level GameBoy::interface->load,save(id, stream) functions instead of stabbing at the raw underlying state inside of various Game Boy core emulation classes. So things are a lot better abstracted now. |

Update to v097r02 release.
byuu says:
Note: balanced/performance profiles still broken, sorry.
Changelog:
- added nall/GNUmakefile unique() function; used on linking phase of
higan
- added nall/unique_pointer
- target-tomoko and {System}::Video updated to use
unique_pointer<ClassName> instead of ClassName* [1]
- locate() updated to search multiple paths [2]
- GB: pass gekkio's if_ie_registers and boot_hwio-G test ROMs
- FC, GB, GBA: merge video/ into the PPU cores
- ruby: fixed ~AudioXAudio2() typo
[1] I expected this to cause new crashes on exit due to changing the
order of destruction of objects (and deleting things that weren't
deleted before), but ... so far, so good. I guess we'll see what crops
up, especially on OS X (which is already crashing for unknown reasons on
exit.)
[2] right now, the search paths are: programpath(), {configpath(),
"higan/"}, {localpath(), "higan/"}; but we can add as many more as we
want, and we can also add platform-specific versions.

Update to v097 release.
byuu says: This release features improvements to all emulation cores, but most substantially for the Game Boy core. All of blargg's test ROMs that pass in gambatte now either pass in higan, or are off by 1-2 clocks (the actual behaviors are fully emulated.) I consider the Game Boy core to now be fairly accurate, but there's still more improvements to be had. Also, what's sure to be a major feature for some: higan now has full support for loading and playing ordinary ROM files, whether they have copier headers, weird extensions, or are inside compressed archives. You can load these games from the command-line, from the main Library menu (via Load ROM Image), or via drag-and-drop on the main higan window. Of course, fans of game folders and the library need not worry: that's still there as well. Also new, you can drop the (uncompressed) Game Boy Advance BIOS onto the higan main window to install it into the correct location with the correct file name. Lastly, this release technically restores Mac OS X support. However, it's still not very stable, so I have decided against releasing binaries at this time. I'd rather not rush this and leave a bad first impression for OS X users. Changelog (since v096): - higan: project source code hierarchy restructured; icarus directly integrated - higan: added software emulation of color-bleed, LCD-refresh, scanlines, interlacing - icarus: you can now load and import ROM files/archives from the main higan menu - NES: fixed manifest parsing for board mirroring and VRC pinouts - SNES: fixed manifest for Star Ocean - SNES: fixed manifest for Rockman X2,X3 - GB: enabling LCD restarts frame - GB: emulated extra OAM STAT IRQ quirk required for GBVideoPlayer (Shonumi) - GB: VBK, BGPI, OBPI are readable - GB: OAM DMA happens inside PPU core instead of CPU core - GB: fixed APU length and sweep operations - GB: emulated wave RAM quirks when accessing while channel is enabled - GB: improved timings of several CPU opcodes (gekkio) - GB: improved timings of OAM DMA refresh (gekkio) - GB: CPU uses open collector logic; return 0xFF for unmapped memory (gekkio) - GBA: fixed sequencer enable flags; fixes audio in Zelda - Minish Cap (Jonas Quinn) - GBA: fixed disassembler masking error (Lioncash) - hiro: Cocoa support added; higan can now be compiled on Mac OS X 10.7+ - nall: improved program path detection on Windows - higan/Windows: moved configuration data from %appdata% to %localappdata% - higan/Linux,BSD: moved configuration data from ~/.config/higan to ~/.local/higan |

Update to v096r07 release.
byuu says: Changelog: - configuration files are now stored in localpath() instead of configpath() - Video gamma/saturation/luminance sliders are gone now, sorry - added Video Filter->Blur Emulation [1] - added Video Filter->Scanline Emulation [2] - improvements to GBA audio emulation (fixes Minish Cap) [Jonas Quinn] [1] For the Famicom, this does nothing. For the Super Famicom, this performs horizontal blending for proper pseudo-hires translucency. For the Game Boy, Game Boy Color, and Game Boy Advance, this performs interframe blending (each frame is the average of the current and previous frame), which is important for things like the GBVideoPlayer. [2] Right now, this only applies to the Super Famicom, but it'll come to the Famicom in the future. For the Super Famicom, this option doesn't just add scanlines, it simulates the phosphor decay that's visible in interlace mode. If you observe an interlaced game like RPM Racing on a real SNES, you'll notice that even on perfectly still screens, the image appears to shake. This option emulates that effect. Note 1: the buffering right now is a little sub-optimal, so there will be a slight speed hit with this new support. Since the core is now generating native ARGB8888 colors, it might as well call out to the interface to lock/unlock/refresh the video, that way it can render directly to the screen. Although ... that might not be such a hot idea, since the GBx interframe blending reads from the target buffer, and that tends to be a catastrophic option for performance. Note 2: the balanced and performance profiles for the SNES are completely busted again. This WIP took 6 1/2 hours, and I'm exhausted. Very much not looking forward to working on those, since those two have all kinds of fucked up speedup tricks for non-interlaced and/or non-hires video modes. Note 3: if you're on Windows and you saved your system folders somewhere else, now'd be a good time to move them to %localappdata%/higan |

Update to v096r06 release.
byuu says: This WIP finally achieves the vision I've had for icarus. I also fixed a mapping issue with Cx4 that, oddly enough, only caused the "2" from the Mega Man X2 title screen to disappear. [Editor's note - "the vision for icarus" was described in a separate, public forum post: http://board.byuu.org/phpbb3/viewtopic.php?p=20584 Quoting for posterity: icarus is now a full-fledged part of higan, and will be bundled with each higan WIP as well. This will ensure that in the future, the exact version of icarus you need to run higan will be included right along with it. As of this WIP, physical manifest files are now truly and entirely optional. From now on, you can associate your ROM image files with higan's main binary, or drop them directly on top of it, to load and play your games. Furthermore, there are two new menu options that appear under the library menu when icarus is present: - "Load ROM File ..." => gives you a single-file selection dialog to import (and if possible) run the game - "Import ROM Files ..." => gives you a multi-file import dialog with checkboxes to pull in multiple games at once Finally, as before, icarus can generate manifest.bml files for folders that lack them. For people who like the game folder and library system, nothing's changed. Keep using higan as you have been. For people who hate it, you can now use higan like your classic emulators. Treat the "Library->{System Name}" entries as your "favorites" list: the games you actually play. Treat the "Library->Load ROM" as your standard open file dialog in other emulators. And finally, treat "Advanced->Game Library" as your save data path for cheat codes, save states, save RAM, etc. ] |

Update to v096r02 (OS X Preview for Developers) release.
byuu says:
Warning: this is not for the faint of heart. This is a very early,
unpolished, buggy release. But help testing/fixing bugs would be greatly
appreciated for anyone willing.
Requirements:
- Mac OS X 10.7+
- Xcode 7.2+
Installation Commands:
cd higan
gmake -j 4
gmake install
cd ../icarus
gmake -j 4
gmake install
(gmake install is absolutely required, sorry. You'll be missing key
files in key places if you don't run it, and nothing will work.)
(gmake uninstall also exists, or you can just delete the .app bundles
from your Applications folder, and the Dev folder on your desktop.)
If you want to use the GBA emulation, then you need to drop the GBA BIOS
into ~/Emulation/System/Game\ Boy\ Advance.sys\bios.rom
Usage:
You'll now find higan.app and icarus.app in your Applications folders.
First, run icarus.app, navigate to where you keep your game ROMs. Now
click the settings button at the bottom right, and check "Create
Manifests", and click OK. (You'll need to do this every time you run
icarus because there's some sort of bug on OSX saving the settings.) Now
click "Import", and let it bring in your games into ~/Emulation.
Note: "Create Manifests" is required. I don't yet have a pipe
implementation on OS X for higan to invoke icarus yet. If you don't
check this box, it won't create manifest.bml files, and your games won't
run at all.
Now you can run higan.app. The first thing you'll want to do is go to
higan->Preferences... and assign inputs for your gamepads. At the very
least, do it for the default controller for all the systems you want to
emulate.
Now this is very important ... close the application at this point so
that it writes your config file to disk. There's a serious crashing bug,
and if you trigger it, you'll lose your input bindings.
Now the really annoying part ... go to Library->{System} and pick the
game you want to play. Right now, there's a ~50% chance the application
will bomb. It seems the hiro::pListView object is getting destroyed, yet
somehow the internal Cocoa callbacks are being triggered anyway. I don't
know how this is possible, and my attempts to debug with lldb have been
a failure :(
If you're unlucky, the application will crash. Restart and try again. If
it crashes every single time, then you can try launching your game from
the command-line instead. Example:
open /Applications/higan.app \
--args ~/Emulation/Super\ Famicom/Zelda3.sfc/
Help wanted:
I could really, really, really use some help with that crashing on game
loading. There's a lot of rough edges, but they're all cosmetic. This
one thing is pretty much the only major show-stopping issue at the
moment, preventing a wider general audience pre-compiled binary preview.

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. |
