im using dstt firmware v1.18. i downloaded the file usrcheat.dat and copied it into my ttfolder. when i go onto rhythm paradise I press select at the game, have cheats turned on, and also have the cheat gold medal/mini games ticked. After i save it and go back to tt menu theres a gold key to let me know cheats are activated. But when i go into the game the cheat isnt working. Its the same for professor layton. Any ideas or tip please?
