How could I do this? I use these backup carts to have all my games in one place and not lose the little cards. I used to use a thing called cart_save.gba for GBA games on my G6 lite and I also used the G6 lite itself to back up the NDS saves but I can't seem to find a way to make it work on the M3 DS Real. I have the expansion for the GBA cart and everything but it won't work. I also would like to backup games that have eeprom saves like ygrassil union so I can play them in an easier format. So yeah how would I go about doing this? I've heard rudolph programs and rein work but I have no real idea how to get them set up.
