Ok. I got Ollydbg (v.2.00.01) from
http://www.ollydbg.de/
I was not able to do point 4a (different menu) When I select the two red nops with shift key, rightclick --->edit--->copy to executable.
Then I right click on new opened window and I select save file. I received no errors. Don't know if this method can be correct.
But when I execute the game (using italian language, as I understood only italian part is patched now) a new popup appears: "Impossible to find the disc in the unit. Insert a disc in the unit g:" cancel,retry,continue.
If I press cancel it quits, if I press continue the other popup window appears: insert cdrom pod.
