Changelog:
- fixed sprite Vflip check
- fixed up window rendering (well, mostly, works great in Megaman II but
not so great in Makaitoushi SaGa)
- added MBC2, MBC5 (already had MBC0, MBC1)
- removed reset, hooked up power cycle and Vsync toggle
- some other stuff
Makaitoushi SaGa locks on the main menu after some graphical glitches on
the title screen, damn.
Shin Megami Tensei - Devichil Black Book locks up immediately, hitting
HALT opcodes all the time, damn again.
Megaman II should be fully playable now.
Contra 3 is really close, but goes crazy on the turtle boss fight.

314 of 512 opcodes implemented, can execute the first 67,450
instructions of Tetris.
I also added an MMIO bus, ala bsnes, so that I can map and access
individual registers with a single indirection.
The source tarball also included empty obj/ and out/ directories which
git does not support.

Project started, so basically everything is new.
It's basically a rough skeleton that mimics bsnes project structure.
Eventually the src/gameboy folder will be copied into bsnes-official and
used by the chip/supergameboy core.
The middleware layer (supergameboy/interface) will be merged into a new
chip/icd2 folder that will represent direct Super Game Boy emulation in
the future.
At least, if all goes according to plan.
There is a simple GUI that can load ROMs, but do nothing after it. It's
not hooked up to ruby yet.
There is a basic system class and interface to expose the
video/audio/input functions.
There is a basic memory bus that doesn't support any MBCs yet.
There is a CPU skeleton that only handles easy read/write access to the
CPU registers (AF is a really fucked up register.)
The core is not hooked up to libco yet, but I intend for it to be, so
that I can run the CPU + LCD how I like.
If it turns out the LCD+audio is easily enslavable, then I'll probably
drop libco and just run it like a regular emulator, using a thread
wrapper around it in bsnes only. We'll see.
The CPU doesn't actually support any opcodes, and loading a ROM won't
actually execute anything.
