would it be possible to manufacture a slot-1 sollution which have a gba connection cable, so that you can connect with other nds/gba games, through that cable? i though that it should boot through the card, or something, cuz it would need the slot-1 still active, right? then the card will provide the software, and hardware that allows you to connect to another gba/nds unit. still cant belive nintendo didnt make some kind of support for gba multiplayer for the nds. could atleast have made it wireless nds-nds connection. maybe a flashcart manufacturer could emulate a cable connected through wifi?
