I've just done a search and come accross a site which seems useful, it explains a few OpenGL issues that the SDL developer might come accross

http://osdl.sourceforge.net/OSDL/OSD...DL-openGL.html

Once I've got my basic game engine sorted out and I'm happy with it, I'll work on an OpenGL version (Technomage, are you busy one weekend?)

I'll have some problems though, none of my textures are powers of 2.. I'll have to write some sort of GL Texture loader which breaks textures into chunks... (getting a migraine just thinking about this) or pads out to the correct size.
