Hi, I just got an R4 and a 3-in-1. I remember reading something abouth patching GBA games with EZ4 Client, or else the game wouldn't save correctly. But Both games I've tried(Advance Wars, WarioWare Inc.) did both save. I flashed the game to NOR, saved, and then switched with the other game(and also backing up the SRAM). There was nothing wrong with any of the saves. They both loaded fine. Is it really neccesary to patch the GBA games, or is it possible to just drag and drop? EDIT: I think I understand. It's all about SRAM size, is it not? Some games need to be patched,others will work just fine?
