So I just purchased a 3 in 1 and am now trying to figure it out. You use a loader in Slot 1 to copy the games in the slot 1 device to either PSRAM or NOR. PSRAM = Faster memory, works for games under 16MB (most GBA games). From there it plays. My question is which loader should I use? As I saw there are 4-5. Also are there any folders that I need to make on the microSD card? Such as "GBA Roms" and "GBA Saves"? EDIT: Nevermind, I found someone else had posted in the GBA Temp->Nintendo DS discussions about the same thing. Sorry, I never have visited that area of the forum before.
