Boris Well I think its possible to create that kind of mod.
First
Edit the tga bearing mod - make him transparent (easy to do it in Fotoshop).
Second
Delete the course ploting tool - (the player will have to plote the corse using a compass only)
Third
Make some changes in TDC.
But with that kind if realizm using a time comprasion can be very dangerous - (Sorry for my bad English)
