FYI --I left a comment on converting 94_Imola(GTR2) at:
http://f1classic.your-talk.com/t7669-circuit-imola-for-gtl
with a better explanation of track conversion (as is).
I've only posted Targa track files here.
I've seen a 93' Imola in development as well.
GTR2 has lots of modern tracks and give me the option of
drivng virtual trackdays for GTL cars.
