I kinda agree with this, sorry for being two years late with this reply, as the DOS version sure runs different. But would that make too much effort, as this webpage only has on supaplex page, (almost) all the runs are done with steam remake of the game, yet it still shows up as the original 1991 version?

I was randomly going through these supaplex level speed runs, and saw level 106 says "waych out" instead of "watch out"
