I didnt make one, sorry, but I do need one, this isnt a must but I know 3d is possible with xp, i've seen it. Sowith all the proper 3d sprites is there a 3d batle system that could be implemented?
I don't think it's possible to make a perfect 3D battle system, but a side-view ABS (animated battle system) with 3D graphics will give the illusion of a 3D battle system. There is someone on these forums doing just that, I suggest you ask him if you need more help. Just look for the "3D rendered graphics" topic in the projects section.
