I downloaded the patch from No Mutants Allowed to fix the colors, but the screen still flickers like a mofo, and it's unplayable with such a big problem.

Does anyone know if something has been made to fix that, and where I can find it? I'd really like to play the first installment.

Did you set the colors to 16 bit after installing the high resolution patch in the new "SCRN" function under Options? I haven't had any screen flickering problems after doing that.

I think I did, and nothing happened. I'll try it again later.

Huh...I just went back and played it again, and no issues. No flicker. Idk what happened, but when a tried it a month ago, it wouldn't work.
