Heh, that's for cloning existing games, but if you still design your own game, convert it from Blitz code to C++, port it over to GBA, send your game concept to Nintendo, or a third party company, see if it meets their standards. If it does, well, then they may put it into mass production with your permission. For a company logo, well, I do somewhat have my own, but to apply my developer logo on there, that's gonna take some thinking... If you don't believe me, I'll just put together my opening game sequence in a minute.
On another note, tho, I'm sort of curious... Can the GBA SP only render 2D games, or can it do 3D? I really haven't noticed the possibilities... Also, what is the screen resolution supported? Last, but not least, what media formats can the GBA SP support? I currently run my games on .PNGs, .WAVs, and .MP3s. I'm not too sure if the GBA can recognize these formats...
