Ozzie, it indeed fixed the issue of the old original Unreal Tournament on newer faster gaming PCs.
I can now play it and leave both cores running

It works great.
Took a long tine to install on both the old 2.4 PC and the new fast PC.
What takes long is it backs up a whole bunch of stuff.
Both PCs are running stable.
I wonder if anyone can find out what they did to address the issue of older games not running on a duo core CPU unless you disable one of them?
All I know is it nice to be able to play the old UT from time to time.
Now they need to address that with Vista too so I can play it on the laptop.
