You gotta pwn it first....google or youtube it. You can run PSone, Sega, NES, GBA, and maybe SNES. I've only tried the GBA and NES Emus on my Ipod and they work good, but I dont like using the touch screen as the buttons. 1st gen. Ipod Touch 16gb....post some sources if you guys can, because I lost damn near all the good ones when I upgraded.
