I have an issue: I have been using my R4DS and cheats for months now, but I have noticed something strange. When using the same usrcheat.dat file, some games cheats' work and others' don't. For instance, New Super Mario Bros.,WWE Smackdown vs RAW 2010, Professor Layton and the Curious Village, and Pokemon Pearl all have cheats available for use, but only the Mario and WWE games work. I have tested with multiple cheats. Is this a possible result of just having a misread rom? I wouldn't think so considering the R4 recognized the rom and matched it with the appropriate cheats, but I have tried everything.
