I have also been looking for NES emulator for pdaXrom, without much success so far.
I have managed to both compile and run InfoNES and fceultra. However InfoNES runs way too fast with sound disabled, and way too slow with sound enabled. fceultra runs way too slow with or without sound.
Both were fairly easy to compile, should you want to do it yourself and have a play around.
