The first released version of NASCAR Racing, v1.0 differs from previous builds.
The noticeable differences I've found from previous builds are:
- Players car changed from #0 to #94, other small graphical changes to the players car
- Main Menu background image changed to match artwork on box cover
- Full field (including players car) changed from 40 cars to 39.
- Larger fonts in SVGA mode updated slightly, more refined.
- Talladega has been updated, the track lines have been adjusted, pit lane changed shape, particularly near the pit road exit.
- When starting a pre-season testing session, the crowd is no longer visable and you start in your pit stall rather than in the middle of pit road.
