Well, I downloaded and put the cheat.dat into my Sys folder, and cheats appear for some games, but they won't appear for my Platinum (U) ad Pearl (U) even though they're on the gamelist. So I went into the R4CCE thing, and checked the Game ID. The Game ID of the rom and the Game ID the cheatslist had are the same. I have tried replacing the .NDS file for my Platinum with no success. At this point, my only thought is that there might have been a mistake, because their addition appears to have been relatively new, when putting the codes in, and that it's not appearing because none of the codes will work or something like that. Oh, and to clarify. The "Cheats (Y)" menu doesn't appear, meaning it doesn't detect cheats for it. I've attempted to use both the USRCHEAT and CHEAT.DAT but not at the same time. And I'm not really sure what to do now I've also tried the cheat database listed here http://gbatemp.net/index.php?showtopic=142609 but had the same problem.
