Homebrew on the 3DS is not yet possible afaik, and I wouldn't encourage anyone to support closed systems like that.
A port to the Caanoo or GCW Zero would probably be possible, but I don't think it's worth the effort if you have to play it without the two nubs.
Maybe someone wants to port it to Android or iOS, for use with the iCP2? Feel free to do so, but you cannot sell it for money unless you remove the music (it has a CC non-commercial license). You can sell my game with different music if you want to (the GPL allows that), and I probably won't take any steps to prevent you from doing that, but I kindly ask you to not be a jerk, and if you decide to sell my game (ported to Android or iOS), then please donate a significant percentage (e.g. 50%) of your profits to the Pandora pre-order fund.
