Sorry but I believe you was already preparing these circuits and so I didn't disturb with my problems.
I like play to GP4 following the same sequence of real Formula 1 and then I am searching for Sochi (Russian GP) and Baku.
For Sochi I have the correct GP4 files (not beautiful track) but for...
I have found Baku and Sochi tracks.
The first contain some type of files (for example):
baku2016.dat
baku2016.wad
that aren't typical GP4 track files.
The second it isn't beatiful track, but we have the possibility to test.
:ok:
