Well the probablem with that is mamewah is written in vb and unless he's using another display library on top of vb, rotation of objects aren't supported for vb, period. Also they aren't supported on any visual studio langauge, for that matter. Directx and opengl are the only popular libraries that can easily rotate objects. So needless to say pmf and myself have a better shot at this point, but we are both running into misc issues that make it not worth it. His already has rotation included, but it's sorta slow and he's having some random problems. I actually have the beginnings of rotation in mine too, but it's equally bad (and incomplete) so I'm not going to activate the code yet.
So it'd doable sorta. But to be honest your better off buying a good video card that supports rotation. No matter how optimized any of us can get it, software rotation will always give slightly poorer performance.
