I don't think that's true. This is from their website. http://www.transgaming.com
The live CVS Tree for TransGaming's WineX (minus copy protection related code and texture compression, for now) is available through VA Linux's SourceForge website.
I use the CVS tree and I have had some success. I've never had anything "work out of the box" but with a little work I can get most games to work fairly well. All the games I install detect DirectX 8.0. As far as the copy protection it's just as easy to get a hacked .exe as getting it to work in the first place.
