Force builtin graphics to overwrite NewGRF?

[zedth0]

I've been futzing with the NewGRF stuff. I have a list of NewGRF that I am liking but there's a road tile in one of the NewGRFs I do not like. Is it possible to make the game use the builtin road tiles instead of a NewGRF? Or do the builtin graphics have a NewGRF I can put into the list?

Unlerss the GRF has a setting to disable/enable that road texture, then my understanding is no. The GRF is simply on, or it is off.

You may be able to place a different road GRF on the list, although I dunno if it will display the roads if it is higher on the list of GRFs, it may be worth trying.
