Update to v104r01 release.
byuu says:
Changelog:
- gba/cpu: synchronize to the PPU, not oneself, when the CPU is
stopped
- this bug was patched in the official v104 release; but not in
the .tar.xz archive
- ms/vdp: backdrop color is on the second 16-entry palette, not the
first [hex\_usr]
- ms/vdp: fix background color 0 priority; fixes Alex Kidd in High
Tech World text boxes [hex\_usr]
- tomoko: choose first option when loading files via the command-line
[hex\_usr]
- icarus: lo/hi RAM addressing was backwards; M68K is big endian;
fixes save files in Sonic 3
Many thanks to hex\_usr for the Master System / Game Gear VDP fix.
That's a tricky system to get good technical information on. The fix
should be correct, but please report if you spot any regressions just in
case.

Update to v102r28 release.
byuu says:
Changelog:
- higan: `Emulator::<Platform::load>()` now returns a struct containing
both a path ID and a string option
- higan: `Emulator::<Platform::load>()` now takes an optional final
argument of string options
- fc: added PAL emulation (finally, only took six years)
- md: added PAL emulation
- md: fixed address parameter to `VDP::Sprite::write()`; fixes missing
sprites in Super Street Fighter II
- md: emulated HIRQ counter; fixes many games
- Super Street Fighter II - status bar
- Altered Beast - status bar
- Sonic the Hedgehog - Labyrinth Zone - water effect
- etc.
- ms: added PAL emulation
- sfc: added the ability to override the default region auto-detection
- sfc: removed "system.region" override setting from `Super Famicom.sys`
- tomoko: added options list to game folder load dialog window
- tomoko: added the ability to specify game folder load options on the
command-line
So, basically ... Sega forced a change with the way region detection
works. You end up with games that can run on multiple regions, and the
content changes accordingly. Bare Knuckle in NTSC-J mode will become
Streets of Rage in NTSC-U mode. Some games can even run in both NTSC and
PAL mode.
In my view, there should be a separate ROM for each region a game was
released in, even if the ROM content were identical. But unfortunately
that's not how things were done by anyone else.
So to support this, the higan load dialog now has a drop-down at the
bottom-right, where you can choose the region to load games from. On the
SNES, it defaults to "Auto", which will pull the region setting from the
manifest, or fall back on NTSC. On the Mega Drive ... unfortunately, I
can't auto-detect the region from the ROM header. $1f0 is supposed to
contain a string like "JUE", but instead you get games like Maui Mallard
that put an "A" there, and other such nonsense. Sega was far more lax
than Nintendo with the ROM header validity. So for now at least, you
have to manually select your region every time you play a Mega Drive
game, thus you have "NTSC-J", "NTSC-U", and "PAL". The same goes for the
Master System for the same reason, but there's only "NTSC" and "PAL"
here. I'm not sure if games have a way to detect domestic vs
international consoles.
And for now ... the Famicom is the same as well, with no auto-detection.
I'd sincerely hope iNES has a header bit for the region, but I didn't
bother with updating icarus to support that yet.
The way to pass these parameters on the command-line is to prefix the
game path with "option:", so for example:
higan "PAL:/path/to/Sonic the Hedgehog (USA, Europe).md"
If you don't provide a prefix, it uses the default (NTSC-J, NTSC, or
Auto.) Obviously, it's not possible to pass parameters with
drag-and-drop, so you will always get the default option in said case.

code (windows may be buggy still)
- HuC6280: PLA, PLX, PLY should set Z, N flags; fixes many game bugs
[Jonas Quinn]
The big thing I wanted to do was enslave the VDC(s) to the VCE. But
unfortunately, I forgot about the asynchronous DMA channels that each
VDC supports, so this isn't going to be possible I'm afraid.
In the most demanding case, Daimakaimura in-game, we're looking at 85fps
on my Xeon E3 1276v3. So ... not great, and we don't even have sound
connected yet.
We are going to have to profile and optimize this code once sound
emulation and save states are in.
Basically, think of it like this: the VCE, VDC0, and VDC1 all have the
same overhead, scheduling wise (which is the bulk of the performance
loss) as the dot-renderer for the SNES core. So it's like there's three
bsnes-accuracy PPU threads running just for video.

Oh, just a fair warning ... the hooks for the SGB are a work in
progress.
If anyone is working on higan or a fork and want to do something similar
to it, don't use it as a template, at least not yet.
Right now, higan looks like this:
- Emulator::Video handles the platform→videoRefresh calls
- Emulator::Audio handles the platform→audioSample calls
- each core hard-codes the platform→inputPoll, inputRumble calls
- each core hard-codes calls to path, open, load to process files
- dipSettings and notify are specialty hacks, neither are even hooked
up right now to anything
With the SGB, it's an emulation core inside an emulation core, so
ideally you want to hook all of those functions. Emulator::Video and
Emulator::Audio aren't really abstractions over that, as the GB core
calls them and we have to special case not calling them in SGB mode.
The path, open, load can be implemented without hooks, thanks to the UI
only using one instance of Emulator::Platform for all cores. All we have
to do is override the folder path ID for the "Game Boy.sys" folder, so
that it picks "Super Game Boy.sfc/" and loads its boot ROM instead.
That's just a simple argument to GameBoy::System::load() and we're done.
dipSettings, notify and inputRumble don't matter. But we do also have to
hook inputPoll as well.
The nice idea would be for SuperFamicom::ICD2 to inherit from
Emulator::Platform and provide the desired functions that we need to
overload. After that, we'd just need the GB core to keep an abstraction
over the global Emulator::platform\* handle, to select between the UI
version and the SFC::ICD2 version.
However ... that doesn't work because of Emulator::Video and
Emulator::Audio. They would also have to gain an abstraction over
Emulator::platform\*, and even worse ... you'd have to constantly swap
between the two so that the SFC core uses the UI, and the GB core uses
the ICD2.
And so, for right now, I'm checking Model::SuperGameBoy() -> bool
everywhere, and choosing between the UI and ICD2 targets that way. And
as such, the ICD2 doesn't really need Emulator::Platform inheritance,
although it certainly could do that and just use the functions it needs.
But the SGB is even weirder, because we need additional new signals
beyond just Emulator::Platform, like joypWrite(), etc.
I'd also like to work on the Emulator::Stream for the SGB core. I don't
see why we can't have the GB core create its own stream, and let the
ICD2 just use that instead. We just have to be careful about the ICD2's
CPU soft reset function, to make sure the GB core's Stream object
remains valid. What I think that needs is a way to release an
Emulator::Stream individually, rather than calling
Emulator::Audio::reset() to do it. They are shared\_pointer objects, so
I think if I added a destructor function to remove it from
Emulator::Audio::streams, then that should work.

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 v101r19 release.
byuu says:
Changelog:
- added \~130 new PAL games to icarus (courtesy of Smarthuman
and aquaman)
- added all three Korean-localized games to icarus
- sfc: removed SuperDisc emulation (it was going nowhere)
- sfc: fixed MSU1 regression where the play/repeat flags were not
being cleared on track select
- nall: cryptography support added; will be used to sign future
databases (validation will always be optional)
- minor shims to fix compilation issues due to nall changes
The real magic is that we now have 25-30% of the PAL SNES library in
icarus!
Signing will be tricky. Obviously if I put the public key inside the
higan archive, then all anyone has to do is change that public key for
their own releases. And if you download from my site (which is now over
HTTPS), then you don't need the signing to verify integrity. I may just
put the public key on my site on my site and leave it at that, we'll
see.

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 v100r01 release.
[This version, with the internal version number changed back to "v100",
replaced the original v100 source archive on byuu.org soon after v100's
release, because it fixes important bugs in that version. --Ed]
byuu says:
Changelog:
- fixed default paths for Sufami Turbo slotted games
- moved WonderSwan orientation controls to the port rather than the device
- I do like hex_usr's idea here; but that'll need more consideration;
so this is a temporary fix
- added new debugger interface (see the public topic for more on that)

Update to v100 release.
byuu says:
higan has finally reached v100!
I feel it's important to stress right away that this is not "version
1.00", nor is it a major milestone release. Rather than arbitrary version
numbers, all of my software simply bumps version numbers by one for each
official release. As such, higan v100 is simply higan's 100th release.
That said, the primary focus of this release has been code
clean-ups. These are always somewhat dangerous in that regressions are
possible. We've tested through sixteen WIP revisions, one of which was
open to the public, to try and minimize any regressions. But all the same,
please report any regressions if you discover any.
Changelog (since v099):
FC: render during pixels 1-256 instead of 0-255 [hex_usr]
FC: rewrote controller emulation code
SFC: 8% speedup over the previous release thanks to PPU optimizations
SFC: fixed nasty DB address wrapping regression from v099
SFC: USART developer controller removed; superseded by 21fx
SFC: Super Multitap option removed from controller port 1; ports
renamed 2-5
SFC: hidden option to experiment with 128KB VRAM (strictly for novelty)
higan: audio volume no longer divided by number of audio streams
higan: updated controller polling code to fix possible future mapping
issues
higan: replaced nall/stream with nall/vfs for file-loading subsystem
tomoko: can now load multi-slotted games via command-line
tomoko: synchronize video removed from UI; still available in the
settings file
tomoko, icarus: can navigate to root drive selection on Windows
all: major code cleanups and refactoring (~1MB diff against v099)
Note 1: the audio volume change means that SGB and MSU1 games won't
lose half the volume on the SNES sounds anymore. However, if one goes
overboard and drives the sound all the way to max volume with the MSU1,
clamping may occur. The obvious solution is not to drive volume that high
(it will vastly overpower the SNES audio, which usually never exceeds
25% volume.) Another option is to lower the volume in the audio settings
panel to 50%. In general, neither is likely to ever be necessary.
Note 2: the synchronize video option was hidden from the UI because it
is no longer useful. With the advent of compositors, the loss of the
complicated timing settings panel, support for the WonderSwan and its
75hz display, the need to emulate variable refresh rate behaviors in the
Game Boy, the unfortunate latency spike and audio distortion caused by
long Vsync pauses, and the arrival of adaptive sync technology ... it
no longer makes sense to present this option. However, as stated, you
can edit settings.bml to enable this option anyway if you insist and
understand the aforementioned risks.
Changelog (since v099r16 open beta):
- fixed MSU1 audio sign extension
- fixed compilation with SGB support disabled
- icarus can now navigate to root directory
- fixed compilation issues with OS X port
- (hopefully) fixed label height issue with hiro that affected icarus
import dialog
- (mostly) fixed BS Memory, Sufami Turbo slot loading
Errata:
- forgot to remove the " - Slot A", " - Slot B" suffixes for Sufami
Turbo slot loading
- this means you have to navigate up one folder and then into Sufami
Turbo/ to load games for this system
- moving WonderSwan orientation controls to the device slot is causing
some nastiness
- can now select orientation from the main menu, but it doesn't rotate
the display

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 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.

- completely removed loadRequest, saveRequest functionality from
Emulator::Interface and ui-tomoko
- loadRequest(folder) is now load(folder)
- save states now use a shared Emulator::SerializerVersion string
- whenever this is bumped, all older states will break; but this makes
bumping state versions way easier
- also, the version string makes it a lot easier to identify
compatibility windows for save states
- SNES PPU now uses uint16 vram[32768] for memory accesses [hex_usr]
NOTE: Super Game Boy loading is currently broken, and I'm not entirely
sure how to fix it :/
The file loading handoff was -really- complicated, and so I'm kind of
at a loss ... so for now, don't try it.
Everything else should theoretically work, so please report any bugs
you find.
So, this is pretty much it. I'd be very curious to hear feedback from
people who objected to the old nall/stream design, whether they are
happy with the new file loading system or think it could use further
improvements.
The 16-bit VRAM turned out to be a wash on performance (roughly the same
as before. 1fps slower on Zelda 3, 1fps faster on Yoshi's Island.) The
main reason for this was because Yoshi's Island was breaking horribly
until I changed the vramRead, vramWrite functions to take uint15 instead
of uint16.
I suspect the issue is we're using uint16s in some areas now that need
to be uint15, and this game is setting the VRAM address to 0x8000+,
causing us to go out of bounds on memory accesses.
But ... I want to go ahead and do something cute for fun, and just because
we can ... and this new interface is so incredibly perfect for it!! I
want to support an SNES unit with 128KiB of VRAM. Not out of the box,
but as a fun little tweakable thing. The SNES was clearly designed to
support that, they just didn't use big enough VRAM chips, and left one
of the lines disconnected. So ... let's connect it anyway!
In the end, if we design it right, the only code difference should be
one area where we mask by 15-bits instead of by 16-bits.

Update to v099r06 release.
byuu says: Changelog: - Super Famicom core converted to use nall/vfs - excludes Super Game Boy; since that's invoked from inside the GB core This was definitely the major obstacle to test nall/vfs' applicability. Things worked out pretty great in the end. We went from 22.0KiB (cartridge) + 18.6KiB (interface) to 24.5KiB (cartridge) + 11.4KiB (interface). Or 40.7KiB to 36.0KiB. This removes a very large source of indirection. Before it was: "coprocessor <=> cartridge <=> interface" for loading and saving data, and now it's just "coprocessor <=> cartridge". And it may make sense to eventually turn this into just "cartridge -> coprocessor" by making each coprocessor class handle its own markup parsing. It's nice to have all the manifest parsing in one location (well, sans MSU1); but it's also nice for loading/unloading to be handled by each coprocessor itself. So I'll have to think longer about that one. I've also started handling Interface::save() differently. Instead of keeping track of memory IDs and filenames, and iterating through that vector of objects ... instead I now have a system that mirrors the markup parsing on loading, but handles saving instead. This was actually the reason the code size savings weren't more significant, but I like this style more. As before, it removes an extra level of indirection. So ... next up, I need to port over the GB, then GBA, then WS cores. These shouldn't take too long since they're all very simple with just ROM+RAM(+RTC) right now. Then get the SGB callbacks using vfs. Then after that, gut all the old stream stuff from nall and higan. Kill the (load,save)Request stuff, rename the load(Gamepak)Request to something simpler, and then we should be good. Anyway ... these are some huge changes. |

Update to v099r03 release.
byuu says: Changelog: - finished cleaning up the SFC core to my new coding conventions - removed sfc/controller/usart (superseded by 21fx) - hid Synchronize Video option from the menu (still in the configuration file) Pretty much the only minor detail left is some variable names in the SA-1 core that really won't look good at all if I move to camelCase, so I'll have to rethink how I handle those. It's probably a good area to attempt using BitFields, to see how it impacts performance. But I'll do that in a test branch first. But for the most part, this should be the end of the gigantic diffs (this one was 174KiB), at least for the SFC/WS cores. Still have the FC/GB/GBA cores to clean up more fully. Assuming we don't spot any new regressions, we should be ~95% out of the woods on code cleanups breaking things. |

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 v098r08 release.
byuu says: Changelog: - nall/vector rewritten from scratch - higan/audio uses nall/vector instead of raw pointers - higan/sfc/coprocessor/sdd1 updated with new research information - ruby/video/glx and ruby/video/glx2: fuck salt glXSwapIntervalEXT! The big change here is definitely nall/vector. The Windows, OS X and Qt ports won't compile until you change some first/last strings to left/right, but GTK will compile. I'd be really grateful if anyone could stress-test nall/vector. Pretty much everything I do relies on this class. If we introduce a bug, the worst case scenario is my entire SFC game dump database gets corrupted, or the byuu.org server gets compromised. So it's really critical that we test the hell out of this right now. The S-DD1 changes mean you need to update your installation of icarus again. Also, even though the Lunar FMV never really worked on the accuracy core anyway (it didn't initialize the PPU properly), it really won't work now that we emulate the hard-limit of 16MiB for S-DD1 games. |

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 v098r03 release.
byuu says:
It took several hours, but I've rebuilt much of the SNES' bus memory
mapping architecture.
The new design unifies the cartridge string-based mapping
("00-3f,80-bf:8000-ffff") and internal bus.map calls. The map() function
now has an accompanying unmap() function, and instead of a fixed 256
callbacks, it'll scan to find the first available slot. unmap() will
free slots up when zero addresses reference a given slot.
The controllers and expansion port are now both entirely dynamic.
Instead of load/unload/power/reset, they only have the constructor
(power/reset/load) and destructor (unload). What this means is you can
now dynamically change even expansion port devices after the system is
loaded.
Note that this is incredibly dangerous and stupid, but ... oh well. The
whole point of this was for 21fx. There's no way to change the expansion
port device prior to loading a game, but if the 21fx isn't active, then
the reset vector hijack won't work. Now you can load a 21fx game, change
the expansion port device, and simply reset the system to active the
device.
The unification of design between controller port devices and expansion
port devices is nice, and overall this results in a reduction of code
(all of the Mapping stuff in Cartridge is gone, replaced with direct bus
mapping.) And there's always the potential to expand this system more in
the future now.
The big missing feature right now is the ability to push/pop mappings.
So if you look at how the 21fx does the reset vector, you might vomit
a little bit. But ... it works.
Also changed exit(0) to _exit(0) in the POSIX version of nall::execute.
[The _exit(0) thing is an attempt to make higan not crash when it tries
to launch icarus and it's not on $PATH. The theory is that higan forks,
then the child tries to exec icarus and fails, so it exits, all the
unique_ptrs clean up their resources and tell the X server to free
things the parent process is still using. Calling _exit() prevents
destructors from running, and seems to prevent the problem. -Ed.]

Update to v097r18 release.
byuu says:
Changelog:
- fixed SNES sprite priority regression from r17
- added nall/windows/guard.hpp to guard against global namespace
pollution (similar to nall/xorg/guard.hpp)
- almost fixed Windows compilation (still accuracy profile only, sorry)
- finished porting all of gba/ppu's registers over to the new .bit,.bits
format ... all GBA registers.cpp files gone now
- the "processors :=" line in the target-$(ui)/GNUmakefile is no longer
required
- processors += added to each emulator core
- duplicates are removed using the new nall/GNUmakefile's $(unique)
function
- SFC core can be compiled without the GB core now
- "-DSFC_SUPERGAMEBOY" is required to build in SGB support now (it's
set in target-tomoko/GNUmakefile)
- started once again on loki (higan/target-loki/) [as before, loki is
Linux/BSD only on account of needing hiro::Console]
loki shouldn't be too horrendous ... I hope. I just have the base
skeleton ready for now. But the code from v094r08 should be mostly
copyable over to it. It's just that it's about 50KiB of incredibly
tricky code that has to be just perfect, so it's not going to be quick.
But at least with the skeleton, it'll be a lot easier to pick away at it
as I want.
Windows compilation fix: move hiro/windows/header.hpp line 18 (header
guard) to line 16 instead.

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. |

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 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.

I trust AWJ's code, and all of the test ROMs I have thrown at it all appear to work great. But better safe than sorry. Same deal for any core changes, it's a lot better to catch it now than after v093 is released. |

Update to v092 hotfix release.
byuu says: For higan: - I fixed the data ROM/RAM initialization for the Cx4, which would periodically cause a crash. - I also moved the Satellaview MaskROM vs FlashROM detection into the Satellaview manifests, so Same Game - Character Data works now. - I also re-added the driver filter to the video shaders, so the D3D driver won't show OGL shaders and vice versa. For ananke: - You can now generate the other SGB images by putting sgb.rom in the same folder as the BIOS images. - I fixed the markup in the database and via heuristics for 5MB+ games (DKJM2, ToP) - Sufami Turbo and BS-X Satellaview generate BML now instead of XML when using heuristics. |

In the release thread, byuu says:
The first official release of higan has been posted. higan is the
new name for bsnes, and it continues with the latter's version
numbering.
Note that as of now, bsnes still exists. It's a module distributed
inside of higan. bsnes is now specific to my SNES emulator.
Due to last minute changes to the emulator interface, and missing
support in ananke, I wasn't able to include Cydrak's Nintendo DS
emulator dasShiny in this build, but I hope to do so in the next
release.

For both new and experienced users, please read the higan user guide
first:
http://byuu.org/higan/user-guide
In the v091 WIP thread, byuu says:
r15->r16:
- BS-X MaskROM handling (partial ... need to split bsx/flash away
from sfc/chip, restructure code - it requires tagging the base
cart markup for now, but it needs to parse the slotted cart
markup)
- phoenixflags / phoenixlink += -m32
- nall/sort stability
- if(input.poll(scancode[activeScancode]) == false) return;
- MSU1 / USART need to use interface->path(1)
- MSU1 needs to use Markup::Document, not XML::Document
- case-insensitive folder listings
- remove nall/emulation/system.hpp files (move to ananke)
- remove rom/ram id= checks with indexing
X have cores ask for manifest.bml (skipped for v092's release, too
big a change)
- rename compatibility profile to balanced (so people don't assume
it has better compatibility than accuracy)

Update to higan v091r14 and ananke v00r03 releases.
byuu says:
higan changelog:
- generates title displayed in emulator window by asking the core
- core builds title solely from "information/title" ... if it's not
there, you don't get a title at all
- sub-system load menu is gone ... since there are multiple revisions of
the SGB, this never really worked well anyway
- to load an SGB, BS-X or ST cartridge, load the base cartridge first
- "File->Load Game" moved to "Load->Import Game" ... may cause a bit of
confusion to new users, but I don't like having a single-item menu,
we'll just have to explain it to new users
- browser window redone to look like ananke
- home button here goes to ~/Emulation rather than just ~ like ananke,
since this is the home of game folders
- game folder icon is now the executable icon for the Tango theme
(orange diamond), meant to represent a complete game rather than
a game file or archive
ananke changelog:
- outputs GBC games to "Game Boy Color/" instead of "Game Boy/"
- adds the file basename to "information/title"
Known issues:
- using ananke to load a GB game trips the Super Famicom SGB mode and
fails (need to make the full-path auto-detection ignore non-bootable
systems)
- need to dump and test some BS-X media before releasing
- ananke lacks BS-X Satellaview cartridge support
- v092 isn't going to let you retarget the ananke/higan game folder path
of ~/Emulation, you will have to wait for a future version if that
bothers you so greatly
[Later, after the v092 release, byuu posted this additional changelog:
- kill laevateinn
- add title()
- add bootable, remove load
- combine file, library
- combine [][][] paths
- fix SFC subtype handling XML->BML
- update file browser to use buttons
- update file browser keyboard handling
- update system XML->BML
- fix sufami turbo hashing
- remove Cartridge::manifest

Update to v091r13 release, and ananke v00r01.
byuu says (about higan): - dropped release/ root node for individual games (still there in ananke's database.) - Memory export uses smarter names (vram.rwm -> video.ram, etc.) - cheat database moved from XML to BML (3.1MB to 1.9MB file size.) - cheat codes moved from XML to BML - resource manifest moved from XML to BML What can I say, I like consistency. But I'll leave the shaders alone until I get around to shader folders. byuu says (about ananke): Works with higan v091r13. Only does SNES stuff so far. |

Update to v091r11 release.
byuu says:
This release refines HSU1 support as a bidirectional protocol, nests SFC
manifests as "release/cartridge" and "release/information" (but release/
is not guaranteed to be finalized just yet), removes the database
integration, and adds support for ananke.
ananke represents inevitability. It's a library that, when installed,
higan can use to load files from the command-line, and also from a new
File -> Load Game menu option.
I need to change the build rules a bit for it to work on Windows (need
to make phoenix a DLL, basically), but it works now on Linux.
Right now, it only takes *.sfc file names, looks them up in the included
database, converts them to game folders, and returns the game folder
path for higan to load.
The idea is to continue expanding it to support everything we can that
I don't want in the higan core:
- load *.sfc, *.smc, *.swc, *.fig files
- remove SNES copier headers
- split apart merged firmware files
- pull in external firmware files (eg dsp1b.rom - these are staying
merged, just as SPC7110 prg+dat are merged)
- load *.zip and *.7z archives
- prompt for selection on multi-file archives
- generate manifest files based on heuristics
- apply BPS patches
The "Load" menu option has been renamed to "Library", to represent games
in your library. I'm going to add some sort of suffix to indicate
unverified games, and use a different folder icon for those (eg
manifests built on heuristics rather than from the database.)
So basically, to future end users:
File -> Load Game will be how they play games.
Library -> (specific system) can be thought of as an infinitely-sized
recent games list.
purify will likely become a simple stub that invokes ananke's functions.
No reason to duplicate all that code.

http://byuu.org/snes/database/database_2012-10-21.bml
Now load any of the 20 games in the database from the file dialog. They
need to be named *.sfc, have no copier header, and have firmware
appended (for Mario Kart only so far.)
If anyone actually does test it, please let me know how it goes for you
and what you think. Note that future versions of higan will have the
database.bml file included with the release.

Update to v091r06 release.
byuu says:
This release adds initial database support.
The way it works is you can now load game folders as you always have, or
you can load a game file. If you load a game file, it tries to create
a game folder for you by looking up the file's sha256 in a database. If
it can't find it, sorry, the game won't play. I'm not hooking up the
oldschool "make up a manifest" code here. The easiest way to handle this
is to get me every game so I can dump it and add it to the database :D
The database entries are complete entries that can be copied directly.
So it describes the board, the information, file layout, etc. That'll be
what comes with higan releases in the future.
Internally, I'm separating the information and board descriptions, and
will use a tool to merge the two together.
Here's a current database copy, with one game in it. Still hammering out
some details, but it's mostly how it's going to look.
cartridge region=NTSC
board type=1CB5B-20
superfx revision=2
rom name=program.rom size=0x200000
ram name=save.rwm size=0x8000
map id=io address=00-3f,80-bf:3000-32ff
map id=rom address=00-3f:8000-ffff mask=0x8000
map id=rom address=40-5f:0000-ffff
map id=ram address=00-3f,80-bf:6000-7fff size=0x2000
map id=ram address=70-71:0000-ffff

Update to v091r05 release.
[No prior releases were posted to the WIP thread. -Ed.]
byuu says:
Super Famicom mapping system has been reworked as discussed with the
mask= changes. offset becomes base, mode is gone. Also added support for
comma-separated fields in the address fields, to reduce the number of
map lines needed.
<?xml version="1.0" encoding="UTF-8"?>
<cartridge region="NTSC">
<superfx revision="2">
<rom name="program.rom" size="0x200000"/>
<ram name="save.rwm" size="0x8000"/>
<map id="io" address="00-3f,80-bf:3000-32ff"/>
<map id="rom" address="00-3f:8000-ffff" mask="0x8000"/>
<map id="rom" address="40-5f:0000-ffff"/>
<map id="ram" address="00-3f,80-bf:6000-7fff" size="0x2000"/>
<map id="ram" address="70-71:0000-ffff"/>
</superfx>
</cartridge>
Or in BML:
cartridge region=NTSC
superfx revision=2
rom name=program.rom size=0x200000
ram name=save.rwm size=0x8000
map id=io address=00-3f,80-bf:3000-32ff
map id=rom address=00-3f:8000-ffff mask=0x8000
map id=rom address=40-5f:0000-ffff
map id=ram address=00-3f,80-bf:6000-7fff size=0x2000
map id=ram address=70-71:0000-ffff
As a result of the changes, old mappings will no longer work. The above
XML example will run Super Mario World 2: Yoshi's Island. Otherwise,
you'll have to write your own.
All that's left now is to work some sort of database mapping system in,
so I can start dumping carts en masse.
The NES changes that FitzRoy asked for are mostly in as well.
Also, part of the reason I haven't released a WIP ... but fuck it, I'm
not going to wait forever to post a new WIP.
I've added a skeleton driver to emulate Campus Challenge '92 and
Powerfest '94. There's no actual emulation, except for the stuff I can
glean from looking at the pictures of the board. It has a DSP-1 (so
SR/DR registers), four ROMs that map in and out, RAM, etc.
I've also added preliminary mapping to upload high scores to a website,
but obviously I need the ROMs first.

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.) |
