Has anyone successfully cracked Mechwarrior 4 yet?
 

Because nothing on GCW works.

Perhaps I am doing something wrong?

Yea, the fixed crack works.
if your cracking the downloaded ISO, copy the mw4.bak file over first and rename it to mw4.exe
then try again.

I haven't used cracks or patches but I have made a perfect 1:1 back-up of the game which I would recommend if you have the proper hardware...if you need help just check out my post!! :P
