Ok, so I have tested some games... as others have said, the NFS's seem to work (I tried 3 and 5). Diablo II surely works, as does System Shock 2 and Star Wars - Force Commander.
Unfortunately that is all I can do right now
However, I cannot see any reason at all why all your games should not work. As others have said, WinME is basically the same as Win98 - therefore most everything should work fine.
What they do not tell you is that WinME is a lot more stable than 98. I can run it for days and days with no problems (unlike 98
) It boots faster and networks better etc etc.
Still, if you can get most things you need on 2000 then you probably have the best system. You realise that the long awaited service pack has just been released for Win2000?? Perhaps it might help you out (if you are really lucky of course)
