Pickle released GLQuake for the Wiz, it’s a Quake engine using nanoGL wrapper. This new version now works with actual firmwares (1.1.0). You must install the OpenGL libraries!

Release notes:

Thanks to jbmaster of gph for providing a patch that fixes the texture issue. All textures should be present. The default for gl_max_size is still 128, although 256 looks so much better, the downside is missing skins, I believe from lack of memory.
