| 18f-22d | 4 for each car | Current position of the cars | Positions are calculated as follow: 00-user car, 01-next car from the drivers2.txt etc., so: 04,06,1a,00 means 4th car,6th car, 26th car and players car - this is not connected with starting grid - probably used only for display |
| 2f0h - 2f0h+51h * number of cars | 51h for each car | CAR's DATA | Each car section starts with 0ffffh Important data is stored at offset 3dh of each CAR DATA - current lap time (after qualifying - lap time - this is used to generate starting positions). I have not figured out why the time stored here is slightly different, than calculated using formula: time=(lap_length*3600)/speed. Simply the track length used here is different than track length from track.txt and even track.trk ! To calculate real track length I'm using STN file (speed) and this time value from offset 3dh Time is stored as: time*1000 (unsigned long) The times are stored in the same order as the cars in drivers2.txt file |
