This question may have already been asked. I searched the forum and didn't find it. It was a brief search, though. I have an R4-3Ds card and my Nintendo DS is acting like there is something wrong with it. It keeps thinking it's "Prince Caspian" and when you try to play it, I get a really pixilated image that says "? menu". I don't own that game or anything. Nothing against Prince Caspian, it's just that I have no idea who he is or what he's doing here. I don't even own his game. Anyway, it's not working out like I planned. Any suggestions? I want to use this cartridge to stomp my foot in the door of the video game programming world. Please tell me what I'm doing wrong. Then also, please send me links to useful Nintendo DS programming sites.
