Fixed bugs
* Less crashes when using compressed roms
New Features
* Rewrote the Background Tile update system, so now it delays changes to the
nametables until the next frame, so that the graphics synchronized properly.
No more disappearing ? blocks in Super Mario Bros. (Punchout and 4-screen
mirroring is currently broken)
Optimizations
* Games run much faster in this version
* Replaced some memory filling/copying loops with faster multi-register
writing code
* Very heavy optimizations to PPU status reads, almost makes PPU hack
unnecessary
* Now stores fixed PRG bank inside Fast Video RAM instead of slow cartridge
slot, huge speedups for this reason
What's broken:
* PPU Hack does nothing right now
* PUNCHOUT is broken
* TQROM and Mapper 74 are broken
* 4 screen mirroring is broken
* Savestates have bugs
* Don't try to use the Cheat Finder right now...
Internal changes which only make sense if you're the developer
* Moved some code out of IWRAM, including the multiplayer link code. (it's
still there, just no longer wasting fast memory)
* Different timeout system
