I have yet to buy the nintendo 3ds but im planning too. Could someone please explain me/advice me what I can do best? http://ombouwen.biedmeer.nl/3DS Here I see 2 types M3i Zero and DStwo. What is the difference, I mean both of them play nds, 3ds, gba backups? Or do I need another card? They don't talk about how much gb the card is...? What else would I need to know?(starting from scratch) Can you play wifi games safely? Can you play gameboy colour and normal gameboy games on them aswell?
