No.......
When you run PJ64 in WinXP mode alot of games don't work.
When you run them in Compatabilty mode you are no longer running them with XP code.
There for even though your Windows edition is XP it is not running it in XP code. This can cause problems with Video drivers and such. OpenGL with ATI for example.
I have heard people say that... oh this OpenGL program works fine and oh that game runs great on D3D and blah blah.... However with my ATI card it is crap on some games.
If you have a Radeon 7500 then maybe we can talk on MSN and you can tell me how to make it run "better on 2000/XP than Win95/98/ME"
Thanks for your reply and help
