First time poster. I just received a 3in1 in the mail today. I have had one before but it was stolen with my last DS. I copied all my games onto the r4 micro SD cart and also put GBAexploader on my cart as well. I have found that all my save files have become corrupt after saving them once and loading the game back up after a few minutes. specifically mother 3 and golden sun. I did everything I did with my first 3in1(from my stolen DS) but now it's not working. I have tried formatting my cart, sram patching my roms and getting different versions of GBAexploader(which didn't even recognize I had a slot2 expansion) please help.
