So I've been reading alot of the threads on picking a slot 2 solution and wanted some clarification. The m3lite perfect sounds like its great but its quite pricey so I'm kind of tempted with the ezflash. So I make a directory called GBA on the sd in my r4ds and I toss 3in1_ExpPack_Tool.nds on my sd. I put my patched roms in GBA directory. Lets say I want to play gbagame1, I go to the 3in1tool, tell it to load gbagame1, then I play for a while and shut off the ds. I want to play gbagame2 next time. I go back to the 3in1tool and load gbagame2. The tool now copies the save game from rom1 to the sd in the r4 and then loads gbagame2. When I go back to play gbagame1 later, gbagame2 save is copied to sd.... Do I have all that down right or is there more hassle and complexity to the game saves when running this combo? I also want to play nes and snes games, it looks like pocketnes will be the way to go under gba mode so it saves the state. Any emulator things to watch out for? Are there any roms that are too big to play under the 3-in-1? Thanks all!
