I have the same problem. I have tried both save files and also battery files (which I thought should work) however none of them seem to work. I get an error message that says "Binary is not compatible with save file. Current SAV generation: 8"
It is an emerald rom. It is a rom hack however as far as I know that should not be a problem either. Does anyone know why I get this problem?
It is this file:
Pokemon - Emerald Version.sav
