Tim Allen 07995c05a5 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SFC: USART developer controller removed; superseded by 21fx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

Tim Allen 67457fade4 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.

Tim Allen 7a68059f78 Update to v099r12 release.
byuu says:

Changelog:
- fixed FC AxROM / VRC7 regression
- BitField split to BooleanBitField/NaturalBitField (in preparation
  for IntegerBitField)
- BitFieldReference removed
- GB CPU cleaned up
- GB Cartridge + Mappers cleaned up
- SFC CGRAM is now emulated as uint15[256] instead of uint[512]
- sfc/ppu/memory.cpp no longer needed; removed
- purged SFC Debugger hooks for now (some of the operator[] calls were
  bypassing them anyway)

Unfortunately, for reasons that defy all semblance of logic, the CGRAM
change caused a slight speed hit. As have the last few changes. We're
now down to around 129.5fps compared to 123.fps for v099 and 134.5fps
at our peak (v099r01-r02).

I really like the style I came up with for the Game Boy mappers to settle
the purpose(ROM,RAM) vs (rom,ram)Purpose naming convention. If I ever get
around to redoing the NES mappers, that's likely the approach I'll take.

Tim Allen f48b332c83 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.

Tim Allen ccd8878d75 Update to v099r07 release.
byuu says:

Changelog:
- (hopefully) fixed BS Memory and Sufami Turbo slot loading
- ported GB, GBA, WS cores to use nall/vfs
- 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.

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.

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.

Tim Allen fdc41611cf Update to v098r14 release.
byuu says:

Changelog:
- improved attenuation of biquad filter by computing butterworth Q
  coefficients correctly (instead of using the same constant)
- adding 1e-25 to each input sample into the biquad filters to try and
  prevent denormalization
- updated normalization from [0.0 to 1.0] to [-1.0 to +1.0]; volume/reverb
  happen in floating-point mode now
- good amount of work to make the base Emulator::Audio support any number
  of output channels
  - so that we don't have to do separate work on left/right channels;
    and can instead share the code for each channel
- Emulator::Interface::audioSample(int16 left, int16 right); changed to:
  - Emulator::Interface::audioSample(double* samples, uint channels);
  - samples are normalized [-1.0 to +1.0]
  - for now at least, channels will be the value given to
    Emulator::Audio::reset()
- fixed GUI crash on startup when audio driver is set to None

I'm probably going to be updating ruby to accept normalized doubles as
well; but I'm not sure if I will try and support anything other 2-channel
audio output. It'll depend on how easy it is to do so; perhaps it'll be
a per-driver setting.

The denormalization thing is fierce. If that happens, it drops the
emulator framerate from 220fps to about 20fps for Game Boy emulation. And
that happens basically whenever audio output is silent. I'm probably
also going to make a nall/denormal.hpp file at some point with
platform-specific functionality to set the CPU state to "denormals as
zero" where applicable. I'll still add the 1e-25 offset (inaudible)
as another fallback.

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.

byuu says:

Changelog:
- GB: support modeSelect and RAM for MBC1M (Momotarou Collection)
- audio: implemented native resampling support into Emulator::Stream
- audio: removed nall::DSP completely

Unfortunately, the new resampler didn't turn out quite as fast as I had
hoped. The final hermite resampling added some overhead; and I had to
bump up the kernel count to 500 from 400 to get the buzzing to go away
on my main PC. I think that's due to it running at 48000hz output
instead of 44100hz output, maybe?

Compared to Ryphecha's:
(NES) Mega Man 2: 167fps -> 166fps
(GB) Mega Man II: 224fps -> 200fps
(WSC) Riviera: 143fps -> 151fps

Odd that the WS/WSC ends up faster while the DMG/CGB ends up slower.

But this knocks 922 lines down to 146 lines. The only files left in all
of higan not written (or rewritten) by me are ruby/xaudio2.h and
libco/ppc.c

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.

  - 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.

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.

Got it. Wow, that didn't hurt nearly as much as I thought it was going
to.

Dropped from 127.5fps to 123.5fps to use Natural/Integer for
(u)int(8,16,32,64).

That's totally worth the cost.

Tim Allen 6c83329cae 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.

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.

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.

Tim Allen f1ebef2ea8 Update to v097r01 release.
byuu says:

A minor WIP to get us started.

Changelog:
- System::Video merged to PPU::Video
- System::Audio merged to DSP::Audio
- System::Configuration merged to Interface::Settings
- created emulator/emulator.cpp and accompanying object file for shared
  code between all cores

Currently, emulator.cpp just holds a videoColor() function that takes
R16G16B16, performs gamma/saturation/luma adjust, and outputs
(currently) A8R8G8B8. It's basically an internal function call for cores
to use when generating palette entries. This code used to exist inside
ui-tomoko/program/interface.cpp, but we have to move it internal for
software display emulation. But in the future, we could add other useful
cross-core functionality here.

Tim Allen cec33c1d0f 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

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.
