how_do_i_do_that said:when you got the game highlighted, press right on your dpad wich will move the frame over to the dot on the right side of the game. in that menu option you turn on the cheats. it is all labeled in the PDF manual on the iTouch website. I suggest you actually read it.
you will need to download the cheat.db, same place where you download the firmware for the latest version. or you can get it here in the download section.
