I just received my M3 Gameboy Expansion Pack, ordered from RealHotStuff. I am using an Acekard 2i with AKAIO 1.8.7 and GBA ExpLoader 0.58b0_MX. I plugged it in, booted up GBA ExpLoader, loaded Kingdom Hearts - Chain of Memories to the SDRAM and started playing. All seemed fine. I rebooted my DS, loaded GBA ExpLoader again, backed up my save file as it prompted, and tried to load a different ROM. This time, I get the Gameboy logo and then a freeze. Since then it seems to ask me to initialize it every time, and I get nothing buy a Gameboy logo/freeze when loading any ROM. Does this happen often? It seems weird that it was fine enough to play a game for 20 minutes or so, save and backup that save, and then just seemingly die on me. Do I need to figure out how to replace this battery, or does it sound like a more serious defect that warrants a return? Sorry if this is a common question, I just need clarification and Google isn't giving me much. Not sure which forum is the most appropriate either. Thanks in advance.
