Hi. Some time ago i found Nitro Engine. a c 3d Engine for DS. I'm trying to make a platform-ball-puzzle game with this. It is really possible. But the engine has limited physics. I'd need some kind of simple ball physics engine for this to complete the game. I'm also making this game for PSP (with ONElua, a new lua interpreter with really good physics) If somebody knows how to add ball-physics for NDS, it would help a lot. This is the intro scene, a rotating planet: I'd also like the 3d obj to be rendered with integer calculations. i mean like the psx did.. and a lot of NDS games do, this engine makes very precise calculations and the objects look smooh. But i'd like to do it faster.
