I am having an issue with one of my games, SuperTux, after it received an upgrade in Adept.

Before, when I played it, I always disabled OpenGL rendering, since my video driver doesn't have OpenGL rendering support, and I am using DRI software acceleration. But now, after the upgrade, there is no Software Rendering option, and it is horribly slow (2 - 4 FPS), more so than a couple light 3D games, which isn't good, since this is a 2D game. I discovered there is a new Config file, but now it is in a ~/.supertux2 folder rather than a ~/.supertux folder. The old one still exists, but it uses the new one, and the new one doesn't have an option for software (sdl) rendering. Is there any way to get it back and working?
