XNES

The Skinny:

Make the ISO or put this crap on your HD with these directories.

put your .nes files in the roms dir (with extention .nes, and the filename is what you will see on the menu)

from the launcher

Y = Exit to dashboard (or evolution X)
A = Select the rom
Up / down (move up 1 down 1)
Left dpad / right dpad (jump down / up the list by filename) // might not work right since files arent sorted
Left trigger / Right trigger (move up fast / down fast)

once the game is launched, you have to reboot to start over, unless you figure it out.

This shit is free, so dont bitch, dont use illegal software, dont fuck your xbox up
dont whine, dont beg from roms, dont be a loser, dont use drugs... ok use drugs.

Peace
