--- Comment #9 from Chris Jones cmsj@tenshu.net --- Thanks very much for helping with the analysis here - I am definitely out of my depth! I don't think I am realistically going to be able to step through the assembly and debug this, but there is at least one other version of the game around, and it can be run in 3dfx/Direct3D/software rendering modes, so I'll try out some permutations and see if anything changes.
