tbh i'm happy with what I have. Currently running normal ds games on 3ds. I'd much rather be able to play gba games and 3ds games on it but i'm not sure what flash cart to use and stuff. Been reading around and its all looking confusing. I have changed the memory card inside it and put a 32gb one in it so I can download games from the e-store as I didnt have enough space for some of them.
@Lynn:-) We may be able to help you play gba and 3ds games if you tell us your firmware version.
