Changelog:
- SMS: background VDP clips partial tiles on the left (math may not be
right ... it's hard to reason about)
- SMS: fix background VDP scroll locks
- SMS: fix VDP sprite coordinates
- SMS: paint black after the end of the visible display
- todo: shouldn't be a brute force at the end of the main VDP
loop, should happen in each rendering unit
- higan: removed emulator/debugger.hpp
- higan: removed privileged: access specifier
- SFC: removed debugger hooks
- todo: remove sfc/debugger.hpp
- Z80: fixed disassembly of (fd,dd) cb (displacement) (opcode)
instructions
- Z80: fix to prevent interrupts from firing between ix/iy prefixes
and opcodes
- todo: this is a rather hacky fix that could, if exploited, crash
the stack frame
- Z80: fix BIT flags
- Z80: fix ADD hl,reg flags
- Z80: fix CPD, CPI flags
- Z80: fix IND, INI flags
- Z80: fix INDR, INIT loop flag check
- Z80: fix OUTD, OUTI flags
- Z80: fix OTDR, OTIR loop flag check

Changelog:
- fixed Super Game Boy regression from v096r04 with bottom tile row
flickering
- fixed GB STAT IRQ regression from previous WIP
- Altered Space is now playable
- GBVideoPlayer isn't; but nobody seems to know exactly what weird
hardware quirk that one relies on to work
- ~3-4% speed improvement in SuperFX games by eliminating function<>
callback on register assignments
- most noticeable in Doom in-game; least noticeable on Yoshi's Island
title screen (darn)
- finished GSU core and SuperFX coprocessor code cleanups
- did some more work cleaning up the LR35902 core and GB CPU code
Just a fair warning: don't get your hopes up on these GB
fixes. Cliffhanger now hangs completely (har har), and none of the
other bugs are fixed. We pretty much did all this work just for Altered
Space. So, I hope you like playing Altered Space.

Changelog:
- GNUmakefile: reverted $(call unique,) to $(strip)
- processor/r6502: removed templates; reduces object size from 146.5kb
to 107.6kb
- processor/lr35902: removed templates; reduces object size from 386.2kb
to 197.4kb
- processor/spc700: merged op macros for switch table declarations
- sfc/coprocessor/sa1: partial cleanups; flattened directory structure
- sfc/coprocessor/superfx: partial cleanups; flattened directory structure
- sfc/coprocessor/icd2: flattened directory structure
- gb/ppu: changed behavior of STAT IRQs
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.

26 hours in, 173 instructions implemented. Although the four segment
prefix opcodes don't actually do anything yet. There's less than 256
actual instructions on the 80186, not sure of the exact count.
Gunpey gets around ~8,200 instructions in before hitting an unsupported
opcode (loop). Riviera goes off the rails on a retf and ends up
executing an endless stream of bad opcodes in RAM =( Both games hammer
the living shit out of the in/out ports pretty much immediately.

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.

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.)
