I've already found a good website to purchase one from. I know I'm going to need it unless Nintendo has these certain GBA games online for download, which happens to not be the case. I've seen what they look like - basically like different sized SD cards and whatnot...

My question is...how do you convert the GBA games to playable versions on a 3DS system? Usually these types of converters involve some sort of cable which doesn't appear to come with the card or the system. That tells me this is some sort of wireless thing...

Still confused! Any help would be great!
