yes, there is. In gamedb.slt go to Races and look for QuickRaceLapCount. There you can edit the laps as you like. I never tested out what the maximum is
If you don't want to enter the lapnumber manually then you can use this SQL Command:
Replace the number 99 with the number of laps of your choiceSQL:UPDATE Races SET QuickRaceLapCount = 99;
what program do I use to do this?
