Did you ever look into this, I'm just wondering if we have a non-graphical-buggy SM64 for Irix floating around these days?That star wipe looks like a mis-set texparam. Looks like the code is trying to use GL_MIRRORED_REPEAT for the texture wrap parameter which didn't exist in OpenGL 1.2/1.3. Unsure there's much to be done about that.
Looking forward to digging into this a bit this weekend, should be fun!
