I can add another to the list. I had a copy of Pang (Ocean/Ocean France), which was a pre-release,which lacks the animals (birds etc.),of the arcade game. I thought this was a deliberate omission until I read a post about it being in the miggy version too!
I'll have to look it up again to check who cracked it though.
A pity noone managed to get a pre-release of Snow Bros. on Amiga though! (As it was done by Ocean France too!)
