Talking about cracked games and other illegal stuff on this site will NOT make you any new friends. Just a friendly advise;)
About Shadow of the Beast though... It is highly optimised for the older Amigas, the A500 in particular. The A600 is quite similar to the A500 so it would probably work there.
You will never get it to run on the A1200, I believe. A kickstart disk will certainly get you nowhere. Maybe, maybe.. if you're lucky there is some type of degrader software that could make it run. Such software could probably be found on Aminet.
