Okay guys, here's how I made it:
I created a good image with alcohol, mounted it in DT4 and used pr0t.st0p.

I do not know what kind of protection this game has, so I tried the latest versions of SR7Stop,SD4Hide,antiblah...nothing worked but pr0t.st0p!
I'm nearly sure that this won't work for everybody of you but I made it on MY system and was successfull with it.
