Help with unsafedisc

[Gojira88]

Ive just used unsafedisc on the .exe and managed to create
a fixed one but i have a couple of questions....


1/ Last time i tried to copy this game i used a no-cd version of
the exe and placed it on the disc before burning. When i
tried to install the game it came up with a message stating
the exe didn't match the exe in the .cab file (or similar). Am
i gonna get the same problem here with the new one EXE?

2/ Is copying the entire files from the cd to hard drive then
replacing the exe all i need to do before burning back?


Please help!!!!
