That's actually a little hard to believe. abc23ds doesn't work, at least everyone who's tried it has failed to get anything but a cube. There's only one program, already mentioned in this thread, that can read the old abc version 6 meshes. Nothing yet tried gets the vcords.

As for the dtx textures, its best to convert them into pcx files with the b2 editor, covert them back to dtx using the nolf editor, then export again as tgas. Or that's how I think it was done. If memory serves, the textures still don't turn out right. JohnnyCrystal says they have to undergo some photoshoping first.
