Hi i am having problems understanding some of the terminology used on Game CopyWorld. When it says copy the whole cd to hardrive how do i do this. I ask this because after that it says Copy the full contents of the original CD to TempDir it says Replace the original main executable with the Fixed Executable or No-CD Executable.
The problem being i can't find the main executable so i can't replce it. I must be doing something wrong. Also i have clone cd and a Plex 16/10/40a which i thought was o.k for copying games without the need for patches or the need to replace any files but i am having no luck at all. I have followed the instructions found on GCW but no joy. I have firmware version 1.O2 is this o.k. Can you point me in the right direction anybody, your help will be much appreciated.
