So I have an R4 with the latest firmware and I downloaded the USRCHEAT.DAT.ZIP from the cheat database. And some of my games have codes but a lot don't. Any game from N-Z has no codes at all. I would understand if I had obscure games, but games such as Pokemon Diamond don't have codes. I think it's too much of a coincidence that every single game after N has no codes but all the games before it are fine. I tried re-downloading it... yet same result. So then I figured I would download the R4 Cheat Code Editor. Except an error occurs every time I try to save my usrcheat.dat file =/ Is it because I have too many games (49) and it will only allow codes for a certain number of games? Or something else I'm not picking up on? Any help/suggestions would be appreciated.
