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

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.

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.

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.
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.

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.

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.
[No prior releases were posted to the WIP thread. -Ed.]

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.

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.

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.)
