hi, i tried to install Singapore track with tsm, but when i start the game, the track has 44 laps like Spa-Francorchamps and not 61. Someone can help me?

The track replaces Spa so thats why it has 44 laps

you need to use GP4 builder to open the .dat file and adjust number of laps

This can also be changed with the great cmagic4_102.
also you can change the timing sector points.
that are contained inside each .dat file.
there are loaded of tutorials on GP4.
regards to all
