So, I tried the unofficial patch and there are a couple of huge problems with it.

Firstly, it runs bad. REALLY REALLY bad. Think <10 FPS kinda bad.

Secondly, it doesn't seem compatible with the widescreen fix.

Thirdly, for god sakes make a standalone package and don't require tracking down a random older patch.

So yeah, really, any way to fix the graphics? Can I just install the widescreen mod on top of it and have it work? I've done that and the title screen reads the version number with the widescreen hack, but I don't know enough about what the unofficial patch changes to know if those changes still apply.
I highly recommend The Protectors mod. It is standalone, totally free and has the widescreen mod implemented.
