I have the same problem to regarding some games. but i read somewhere online that the cheat codes differ or in this case don’t work because of the game ROM. you need the correct game ROM( game ROM region or in some cases ROM version).
I love Gain Ground on the Genesis but none of the cheats work but i have luck with CONTRA III on the SNES with cheats used from the GAME GENIE folder.
i haven’t tried Mario yet. i have the RPi B+ model but I just got my RPi 2 today. So i will install Retropie on it later today.
