Found this.......
http://www.gameboy-advance.net/ looking more into it, but just looks like you have to have EXISTING games and can upload them. I'm not looking to make any fancy looking games, but possibly games with just regular ole gameboy color technology but would be cooler to make nicer looking ones. Thx.
EDIT: Fixed link. Yeah i'm 100% sure that what I linked to just lets you load just about any media type file onto the Gameboy Advance SP. Which is helpful cuz when I find a way to make a game I know what I need to load it up on at least(or if I find out how to actually just load the game onto a blank one that way) so yeah.
