So I purchased a Nintendo DS Lite recently, so I am now able to play GBA catridges or flashcards as well as NDS cartridges or flashcards. I have been playing some Pokémon Roms (not hacks) through RetroArch on my n3DS. Such as Leaf Green for GBA with Gpsp. If I have been playing Leaf Green and training pokemon with RetroArch on my n3DS is there any possibility that- a) I can migrate this save file to a (Gen III) GBA cartridge and trade these Pokemon (Gen III to Gen IV) to a (Gen IV) NDS Cartridge? b) Purchase a GBA flashcard and use my current LeafGreen save (Gen III) to continue playing on the DS Lite Slot 2 and trade these Pokemon (Gen III to Gen IV) to a (Gen IV) DSTwo Flashcard? I not sure if they are both possible or which one of those methods is the correct one? Any insight would be helpful.
