Need help to copy a game

i bough a game ( swedish game called hjarnkontoret)
and i found out that this game got safedisk 1 protection but i cant find the *.icd file to make a crack to my game.
The realese of safedisk 1 is r4.
My recorder dont support raw so i has to get / do a crack
With unsafedisk you must get a *.icd file and there is no one.Anyone got this problem before or know what to do.
