I want to migrate pokemon over from my M3 to my R4 in slot 1. Usually when you have a legit pokemon gba game, it would pop up as an option in the DS pokemon screen to migrate the pokemon. I lost my legit leaf green version but still want to migrate gba pokemon to my slot 1 card. I have an m3 mini-sd that act like a r4 but for gba games. Is it possible to boot leaf green from the gba while in R4. I dont mean like just booting the game in an R4 but to to boot both slot 2 and slot 1 at the same time in order to migrate pokemon from my m3 to my r4. Any help appreciated. Thanks in advance! Sorry if im unclear
