after spending 20 minutes inputting a golden password for golden sun 2, i tried saving the game and much to my horror it said "Could not find backup data" and thusly i was unable to save my game
I think this can be corrected using Visual Boy Advance emulator. Use it to enter the password to transfer your progress and then maybe play for a minute or two, and then save. Transfer the save to your EZ Flash IV cart.
Set Visual Boy Advance save settings to Automatic (or Flash, I can't remember) and 64K for the size. You could also try SRAM patching the game with GBATA and then trying directly on the EZ Flash IV again. Give VBA a shot though, it should work, and please report back to let us all know the status. Thanks Grink.
I guess I shouldn't assume by your gbatemp join date that you know the basics. My fault entirely. I apologize. Use the EZ Flash Client to send roms to your mini sd card.
