I think you would need a vector [sin(deg],cos(deg)], which 'flows' over the VIDEO_MEM, while you just take bit for bit your
sprite. I did a similar thing on the PC, see my homepage, PC section, VDREAM.

> Does anyone know how to rotate a sprite on the screen (w/out USGARD, in case you are wondering...)  I need to turn a simple
15x15 sprite around sideways.  I'm not really quite sure how to do sin/cos rotations (I have no idea how sin/cos even can do
rotations) but if someone can help it will be greatly appreciated
