The art assets from Tyrian 2000 are a lot more legally dubious to reuse (Tyrian's were released in the public domain IIRC, but the new art in 2000 is from a different artist), and I don't even like what Tyrian 2000 added in the first place.

Nevertheless I want to make sure Tyrian 2000's data files work if someone puts them there.

Maybe this will result in a proper OpenTyrian2000, at some point down the line.
