spinal	Here is what I have so far, does anyone feel like helping? It doesn't look right.

CodersRule	Is it _supposed_ to lag like that?

Jayenkai	It's meant to be for the DS. For various reasons it becomes more awkward for Spinal if he enables 3D mode. Working on DSision means he has to be extremely cautious of the memory he uses. (I think...from past chats!) -=-=- ''Load, Next List!''

spinal	I have it working on the DS now, I'm using 3D, but because 3D doesn't work properly in the palib version I have (I only have access to 3d 'sprites' which are made up of 4 polys I think) and the rotation functions dont seem to work right. Either way, it now works the way I want it, after a bunch of cheating. At a reasonable speed also, which is nice. -=-=- Check out my excellent homepage!
