As for jailbreaking, it couldn't be easier!!!!
google blackra1n, i believe the site in actually blackra1n . com, download the program, follow the installer!! let it jailbreak your ipod and install cydia!!!
Once all is installed, open cydia, navigate to the add source section: add the sources below which you'd like:
or snes - iromsrepo.com/Cydia/snes/
for gameboy/gameboy color - iromsreop.com/Cydia/gameboy/
for gba - iromsrepo.com/Cydia/gba/
for genesis - iromsrepo.com/Cydia/genesis/
make sure u put in the capital letters.
hope this helps!
