A pre-release version of the Test Drive Disc (PCPX-96088 | Aug 2, 1997). This NTSC DEMO build is almost identical to the Test Drive Disc (PCPX-96088). The only difference I've noticed is, the replays does not show how many laps the race has and you can't change the Camera on the replay. The Test Drive Demo (PCPX-96088) probably has other bug fixes compared to NTSC DEMO that I am not aware of. I was considering making a video at all, because the content is otherwise absolutely identical. However, since it is nonetheless a different build, I decided to make a video and upload it here.
