i also have both warcraft 3 ROC and TFT cds both from US, i have installed CloneCD 188.8.131.52 (eval version) and used Lite-ON LTC-48161H to burn my image...
after burning, i installed the game and it went fine, then i tried to play it, the funny thing is that when i tried to play i received this error msg
"Please insert the original CD, not a backup CD"
or something like that, the words "backup CD" are in the message box, i said "huh???" how did it know that it is just a backup copy??? stomps me, havent tried any other software yet, but does anyone here have the same problem as me?
