Hello, firstly yes. Although I'm new to the site, I am not new to the scene, I am aware of how a R4 basically runs, what I would like to do is to be able to somehow flash one with a single ROM so say it was for arguments sake, Mario Kart, the Mario Kart message would appear on the DS menu and it would boot straight into Mario Kart. I would prefer to be able to do this on a cartridge with SD capabilites (so if there if there is an old flashcard I'm not aware of that would be great.) If not though, I would like to be able to do it on an R4. Can anybody help or provide any information?
