Don’t worry this will probably be the last “share your” topic from me. I expect to see a lot of pokemon and mariokart. My MarioKart DS friend code is 4000-3236-4573

You also no longer need Action Replay or an R4 cart. watch mrbean’s video here: How to play DS games online after Nintendo WFC Shutdown! No hacks or mods required! (Wiimmfi) - YouTube
