It actually works! And it is perfectly legal.. wow. THANK YOU
EDIT: I copied Skies_central.gtr to skies_north.gtr and skies_south.gtr, so I do not have to edit the .trk file every time. I also installed gtl-gtr successfully so I can drive more than one car. This solution also creates HAT files in Documents/gtr2 so it is all that i needed. What a wonderful pre-christmas present
Thank you!Found HD skies for GTR2.. so no need to rename..
