Dewit has updated PocketNES, a NES emulator for Gameboy Advance (also compatible to the Nintendo DS).

Changes:

* More speedups from using EWRAM to store rom pages (instead of reading them from the cartridge)
* Many savestate fixes
* Now uses correct identification for savestates created with compressed roms. Old savestates made with compressed roms will not work.
* Added in something developed a year ago and then I forgot to merge it in o_O (I thought it had been integrated in, but apparently it wasn’t)
* Fixed cheats getting lost after loading state
* Fixed compressed VS games
* Some internal code changes to allow certain features to be excluded at build time
