Thanks, Kris. That'll really help those of us with WW and TT installed who are trying to build RCT2-friendly scenarios for people without WW or TT.

Ditto the above. It will also keep me from deleting things I shouldn't. Thanks!!!

Very handy thanx Kris!

I'd like to put together a dat file list so that everyone knows the corresponding names to the files you've listed. Does anyone know if this has already been done? If not I'll get started on it. I've already done some of them.

I am pretty sure that hasn't been done yet.

I think that the RCTDB has the entire list of the scenery objects from RCT2, WW and TT listed. That would be one place to check. Since I haven't done a search in there for quite some time, I don't know if that also includes the rides as well.

Really helpful!
