I want to run several backups from my efa linker using the GBA loader. However two of the games have sound glitches and are slower, however when I run the game (Sonic advance 3) without the loader it works fine and I have tried pogoshell and again it works fine. Is there an alternative loader or solution besides pogoshell? It is an EFA simple BTW. Also on a side note does anyone know why this has a battery even though there is no RTC? I know its a simple because the client/drivers for the original dont work with it. Edit: this problem also happens when launched in NDS mode with flashme. Edit2: Just tried pogoshell, Sonic advance 3 works fine but Sonic advance 2 doesnt save (but does in the emulator).
