I want something white that'll fit into my ds lite slot without sticking out(preferably) and be white and I have an R4, and I heard some flashcarts don't work with r4 which i don't really get so someone explain that to me please. i'll probably just be playing pokemon hacks. also, how many games do most flash carts hold? I think this was structured very oddly so i hope you guys understand this. edit: i meant a cart that will play gba games by the way, just in case you didn't get me.
