dude good new.
thx for your help Cowsheep and PopFan
with unpacked one i cracked part of it.
now its doesnt show this error any more when starting the game.
but it has more checks.
if you modify anything on dvd, the game doesnt start.
will need to find i, where this dammit check is.
@Cowsheep you dont need to modify the hardcoded part.
you need to edit mov part. look at the picture:
