If it seems like i've no idea what i'm talking about, then that's probably the case.
Since I accidentally bought an n-card on eBay (with ROMs already on it) I've spent a few hours looking into the whole homebrew thing (for my DS) and come up with not a whole lot.
My main question is: is the n-card I've already got fine for adding ROMs (that I've since downloaded) to, or do I need Slot-2 equipment as well? Also, does a ROM like this support multiplayer well? and finally, is there any particular reason why when I load a game (in this case Mario Kart :D )all i get is a black screen?
Apologies if these questions are awy too over-specific, just wondered if I could get a few answers and save myself a couple of quid ;)
