skidmt1 or skidmt2 should either one work.
There are two track disks, and two car disks. Whichever one(s) you insert when prompted picks which tracks and cars available for the upcoming race.
Skidmarks is a buggy program, though, to say the least. I remember back in the day, I had to download a cracked version just to play it, despite having BOUGHT it. Grrrr....
You may need to be in PAL, even for the NTSC version, as well. Not one of the more intelligently coded games, but fun once it gets working.
