The existing ppc implementation in libco only supports
the ELFv1 ABI on PowerPC 64 and therefore can't be used on
Little Endian systems and Big Endian systems running ELFv2
distros.
This commit introduces a new implementation of the libco
API for ppc64 elfv2. It has been tested with bsnes and higan.
The original ppc implementation is maintained for non-ELFv2
targets.

- ruby: fullscreen support for Windows OpenGL 3.2, DirectDraw 7.0, GDI drivers
- ruby: output(width, height) support for all drivers on all platforms
- hiro: improve focus capture for Canvas and Viewport widgets
- hiro: added two hotfixes for the macOS Cocoa target [Sintendo]
- higan, bsnes: focus the viewport after leaving fullscreen exclusive mode
- freebsd: moved from GCC 8.2.0 to Clang 6.0.1
- higan: added video display emulation option to Famicom and Mega Drive cores
The reason I moved to Clang was because GCC keeps deadlocking my FreeBSD system.
I don't know if it's GCC's fault, or suddenly running 32 copies of any high-CPU
usage program, heh. But at any rate, it's worth a try. The performance is the
same, but compilation takes a tiny bit longer with Clang.

I finally pass blargg's dmg-sound and cgb-sound tests, but at quite a cost.
Reads and writes can't happen on an exact T-cycle (clock cycle) point within an
M-cycle (opcode cycle) for the DMG. Writes to trigger take effect two clocks
after writes to wave RAM, for instance. Probably going to be a lot more of this
in low-level PPU emulation, so I'm biting the bullet and slowly converting the
Game Boy bus handler to this new format, which I'll use as a test bench for
doing this later to other systems with, since Game Boy performance isn't as
critical (it's a drop from 220fps to 200fps to have to poll the bus four times
per memory access and synchronize the CPU four times as often, so a lot less bad
than I'd feared at least.)

Changelog:
- ruby/audio/xaudio2: ported to new ruby API
- ruby/video/cgl: ported to new ruby API (untested, won't compile)
- ruby/video/directdraw: ported to new ruby API
- ruby/video/gdi: ported to new ruby API
- ruby/video/glx: ported to new ruby API
- ruby/video/wgl: ported to new ruby API
- ruby/video/opengl: code cleanups
The macOS CGL driver is sure to have compilation errors. If someone will
post the compilation error log, I can hopefully fix it in one or two
iterations of WIPs.
I am unable to test the Xorg GLX driver, because my FreeBSD desktop
video card drivers do not support OpenGL 3.2. If the driver doesn't
work, I'm going to need help tracking down what broke from the older
releases.
The real fun is still yet to come ... all the Linux-only drivers, where
I don't have a single Linux machine to test with.
Todo:
- libco/fiber
- libco/ucontext (I should really just delete this)
- tomoko: hide main UI window when in exclusive fullscreen mode

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.

Note: for Windows users, please go to nall/intrinsics.hpp line 60 and
correct the typo from "DISPLAY_WINDOW" to "DISPLAY_WINDOWS" before
compiling, otherwise things won't work at all.
This will be a really major WIP for the core SNES emulation, so please
test as thoroughly as possible.
I rewrote the 65816 CPU core's dispatcher from a jump table to a switch
table. This was so that I could pass class variables as parameters to
opcodes without crazy theatrics.
With that, I killed the regs.r[N] stuff, the flag_t operator|=, &=, ^=
stuff, and all of the template versions of opcodes.
I also removed some stupid pointless flag tests in xcn and pflag that
would always be true.
I sure hope that AWJ is happy with this; because this change was so that
my flag assignments and branch tests won't need to build regs.P into
a full 8-bit variable anymore.
It does of course incur a slight performance hit when you pass in
variables by-value to functions, but it should help with binary size
(and thus cache) by reducing a lot of extra functions. (I know I could
have used template parameters for some things even with a switch table,
but chose not to for the aforementioned reasons.)
Overall, it's about a ~1% speedup from the previous build. The CPU core
instructions were never a bottleneck, but I did want to fix the P flag
building stuff because that really was a dumb mistake v_v'

This release marks a major step forward, offering full low-level
emulation of all four DSP coprocessors based on the NEC uPD77C25
processor core. Many people were responsible for this milestone: Dr.
Decapitator for the actual decapping and extraction; Lord Nightmare for
the cartridges and some special analysis tools; myself, Jonas Quinn and
Cydrak for the uPD77C25 emulation; and all of the donors who raised the
necessary $1,000 for the necessary hardware and equipment needed to pull
this all off. To say thanks to the donors, I am releasing the uPD77C25
emulation core to the public domain, so that everyone can benefit from
it.
All four DSP emulations will be improved by this by way of having
realistic timing; the DSP-4 will benefit further as the high-level
emulation was incomplete and somewhat buggy; and the DSP-3 will benefit
the most as the high-levle emulation there was not complete enough to be
playable. As a result, most notably, this means bsnes v073 is the first
emulator to fully be able to play SD Gundam GX (J)!
As bsnes' primary goal is accuracy, the LLE DSP support renders the old
HLE DSP support obsolete. Ergo, I have removed the 166KB of HLE source
code, and replaced it with the uPD77C25 core, which comprises a mere
20KB of source code. As this LLE module supports save states, this also
means that for the first time, DSP-3 and DSP-4 games have save state
support.
On the other hand, this also means that to run any DSP game, you will
need the appropriate program ROM. As these are copyrighted, I cannot
distribute them nor tell you where to get them. All I can do is provide
you with the necessary filenames and hashes.
Changelog (since v072 release):
* added NEC uPD77C25 emulation core
* added low-level emulation of the DSP-1, DSP-1B, DSP-2, DSP-3, DSP-4
coprocessors
* removed high-level emulation of the DSP-n coprocessors
* added blargg's libco::ppc.c module, which is far more portable, even
running on the PS3
* added software filter support via binary plugins
* added debugger (currently Linux-only); but it is as yet unstable
* added pause shortcut
* updated mightymo's cheat code database
This release greatly polishes the user interface, adds a new cheat code search utility, adds the snesfilter library, and adds Qt-based GUI support to both snesfilter and snesreader. snesfilter gains 2xSaI, Super 2xSaI and Super Eagle support, plus full configuration for both the NTSC and scanline filters; and snesreader gains support support for multi-file ROM archives (eg GoodMerge sets.)
Statically linking Qt to bsnes, snesfilter and snesreader would be too prohibitive size-wise (~10MB or so.) I have to link dynamically so that all three can share the same Qt runtime, which gets all of bsnes and its modules to ~1MB (including the debugger build); and Qt itself to about ~2.5MB.
However, there is some bad news. There's a serious bug in MinGW 4.4+, where it is not generating profile-guided input files (*.gcno files.) There is also a serious bug in Qt 4.5.2/Windows when using dynamic linking: the library is hanging indefinitely, forcing me to manually terminate the process upon exit. This prevents the creation of profile-guided output files (*.gcda files.) It would be tough enough to work around one, but facing both of these issues at once is too much.
I'm afraid I have no choice but to disable profile-guided optimizations until these issues can be addressed. I did not know about these bugs until trying to build the official v053 release, so it's too late to revert to an all-in-one binary now. And I'm simply not willing to stop releasing new builds because of bugs in third-party software. As soon as I can work around this, I'll post a new optimized binary. In the mean time, despite the fact that this release is actually more optimized, please understand that the Windows binary will run approximately ~10% slower than previous releases. I recommend keeping v052 for now if you need the performance. Linux and OS X users are unaffected.

A new version of bsnes has been released. It contains a few minor emulation fixes, as well as user interface improvements. Behind the scenes, the source has been cleaned up more in preparation for running the CPU and PPU (video processor) separately from each other (eg with no enslavement.) This is required for implementing a clock cycle based PPU renderer.
- Greatly improved invalid DMA transfer behavior, should be nearly perfect now
- Major code cleanup -- most importantly, almost all PPU timing-related settings moved back to PPU, from CPU
- Added option to auto-detect file type by inspecting file headers rather than file extensions
- Rewrote video filter system to move it out of the emulation core -- HQ2x and Scale2x will work even in hires and interlace modes now, 50% scanline filter added
- Re-added bsnes window icon
- Added new controller graphic when assigning joypad keys [FitzRoy]
- Redundant "Advanced" panel settings which can be configured via the GUI are no longer displayed
- Improved speed regulation settings
- XP and Vista themes will now apply to bsnes controls
- Added "Path Settings" window to allow easy selection of default file directories
- Tab key now mostly works throughout most of the GUI (needs improvement)
- Main window will no longer disappear when setting a video multipler which results in a window size larger than the current desktop resolution
- Added two new advanced options: one to control GUI window opacity, and one to adjust the statusbar text
