Changelog:
- rewrote the 6502 CPU core from scratch. Now called MOS6502,
supported BCD mode
- Famicom core disables BCD mode via MOS6502::BCD = 0;
- renamed r65816 folder to wdc65816 (still need to rename the actual
class, though ...)
Note: need to remove build rules for the now renamed r6502, r65816
objects from processor/GNUmakefile.
So this'll seem like a small WIP, but it was a solid five hours to
rewrite the entire 6502 core. The reason I wanted to do this was because
the old 6502 core was pretty sloppy. My coding style improved a lot, and
I really liked how the HuC6280 CPU core came out, so I wanted the 6502
core to be like that one.
The core can now support BCD mode, so hopefully that will prove useful
to hex\_usr and allow one core to run both the NES and his Atari 2600
cores at some point.
Note that right now, the core doesn't support any illegal instructions.
The old core supported a small number of them, but were mostly the no
operation ones. The goal is support all of the illegal instructions at
some point.
It's very possible the rewrite introduced some regressions, so thorough
testing of the NES core would be appreciated if anyone were up for it.

Changelog:
- lots of code cleanups to processor/r6502 (the switch.cpp file is only
halfway done ...)
- lots of code cleanups to fc/cpu
- removed fc/input
- implemented fc/controller
hex_usr, you may not like this, but I want to keep the controller port
and expansion port interface separate, like I do with the SNES. I realize
the NES' is used more for controllers, and the SNES' more for hardware
expansions, but ... they're not compatible pinouts and you can't really
connect one to the other.
Right now, I've only implemented the controller portion. I'll have to
get to the peripheral portion later.
Also, the gamepad implementation there now may be wrong. It's based off
the Super Famicom version obviously. I'm not sure if the Famicom has
different behavior with latching $4016 writes, or not. But, it works in
Mega Man II, so it's a start.
Everyone, be sure to remap your controls, and then set port 1 -> gamepad
after loading your first Famicom game with the new WIP.

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.

Changelog:
- fixed cartridge load window focus on Windows
- lots of updates to nall, ruby and phoenix
- ethos and Emulator::Interface updated from "foo &bar" to "foo& bar"
syntax (work-in-progress)
Before I had mixed the two ways to declare variables/arguments all over
the place, so the goal is to unify them all for consistency. So the
changelog for this release will be massive (750KB >.>) due to the syntax
change. Yeah, that's what I spent the last three days working on ...

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.)
