download the latest usercheat.dat from filetrip.net, then, if your using the flashcart firmware, copy it to the system folder, and if your using ysmenu, copy it to the ttmenu folder. you can also create your own usrcheat.dat, i recomend this becuase the downloaded one sometimes doesnt have the game your playing, or it is too big in size, and crashes constantly because of this. i believe the program used to make your own is cheat code editor, something like that, and google ("name of game" action replay codes)
