Does anyone know how to transfer saves from an original GBA cart or just downloaded GBA saves to an M3? I know it can be done with DS saves. I bet there's patching involved.
No patching involved, just using the game manager to convert the save file. What you need is a .sav save file. You need to go into gamemanager and find the GBA game on your SD/CF card and double click on it, this opens a save file manager, select the save file you want to overwrite (usually only one available) and then click on Write Sav, find you .sav file and your done. If your backing them up from an original cart you need to download a homebrew program for the M3, I havn't used it for ages so can't tell you what it's called - but it does exsist.
