Is there a NoCD fix that works 100% for the Sims 2 U.S. version?

[Ewoud]

what exactly doesnt work? the conversion or playing the afterwards?

for conversion you need the 4 CD international version.
For the fixed exe to work you need to copy the .TMP files from the mini image to your copy DVD. To play the game you still need the copy DVD in your drive

you are doing something wrong, it works!
