I know you can get multiple emulators on a jailbroken iPod touch. I have not jailbroken, but am considering it. So, I would like to know if the emulators are able to use cheat codes. Like, can the GBA Emulator use Gameshark/Action replay codes? Also, what emulators can the iPod touch 4g use now? I know GBA, GBC, NES are possible, any others? Thank you in advance.
