Well i have flash2advance very looong time, and i was wondering is there any way to use it for 'backuping' (^^) my nds games so i can play on roms? Thanks in advance!
Possibly, but to be honest, it's not worth doing, most GBA flashcarts are really bad at playing NDS games, as they were not designed for it, plus you would still need to buy a Passcard for it to work in DS mode.
