Been browsing ancient clan sites and the QUTA site is still up and has loads of awesome old demos.
Quakeworld how it is meant to be played (five keyboard players on 250ms camping RL on dm3).

Hmm they don't work though.

"Server returned version 24, not 28"

Yeah sorry, I should have said you have to play them through qizmo (http://www.nisda.net/files/qizmo291.zip) to get them to work.

and its possible to convert them to .mvd if im not mistaken??
