Both of the above come with stock GLQuake and stock WinQuake and no CD sound track.
Original GLQuake and WinQuake are quite buggy with rendering issues, hardware compatibility issues and an NAT issue with routers that causes a "connection accepted" situation when trying to connect to a server.
For the best experience, it is recommended that you upgrade your client to a modern debugged engine (see QuakeOne homepage).
