I found this just there a few minutes ago and found it interesting. Its how to race at night. Here is how: Go into where the track files are located for your game, such as: C:\Program Files\RACE 07 Offline\GameData\Locations\Zolder (or whatever track you want to change),Copy Zolder so that you have to Zolder circuits. Rename one Zolder Night. Then open the GDB file for Zolder Night in Notepad, and in there you can change the times for when each session starts, so just change the times and save the file: TestDayDay = Wednesday TestDayStart = 15:30 Practice1Day = Saturday Practice1Start = 15:00 Practice2Day = Saturday Practice2Start = 18:30 QualifyDay = Saturday QualifyStart = 20:00 WarmupDay = Sunday WarmupStart = 20:30 RaceTime = 25 RaceTimeScaled = 25 Race1Day = Sunday Race1Start = 21:30 Race1Laps = 11 RaceLaps = 11 Race2Day = Sunday Race2Start = 23:00 Race2Laps = 11 Click save and you are done. Heres proof: Also If you change the time to 04:00 you can race at dawn Tracks that work: Monza* Valencia* Spa Zolder Donington Zhuhai Themalito Le Mans (Virtua_LM) Mid-Ohio (Virtua LM) Misano There probably others but I haven't tried all the tracks. If you convert the following from GTR 2 they have lighting that works: Adeleide** Long Beach** St Petersburg** Cleveland Airport** Birmingham Superprix Night** Thanks to Jon Trotter for this!
