Installation
1. Untar the emulator tarball onto some directory on your SD card.
2. You must have a directory called /roms/nes on your SD card.
Put the roms in there, i.e. /mnt/sd/roms/nes is the gp2x path.
Rom files can be zipped.
3. The emulator will create a subdirectory under roms
/roms/nes/fceultra. Save states etc. go here.
4. To start a different rom while running one, hit L+R+JOY.
To exit the file selection menu, press start.
5. For FDS support, put disksys.rom in /mnt/sd/roms/nes/fceultra
Note: FDS roms must not be zipped.
6. For GameGenie support, put gg.rom in /mnt/sd/roms/nes/fceultra
