Uhh i was not looking into sub.lgp, but i looked into cycle-race, and there is everything, city background textures, road textures, road models, motorcycle models, character faces which appear at bottom of the screen ...
and also i looked into fort condor minigame, and also there is everything available (whole hill-with-eagle background, all units models...)
so i pressume that it should be in sub.lgp aswell. I'll look at it in the evening and i'll refer what i found tomorrow.
--- edit ---
uh yes its true, there are only few texture files inthere ... then i dunno ...
