@Graham: Could your CD be defective? I received my CD + floppies, and CD did boot in CD32 and I was able to play Bridge Strike. My PC did recognize CD too.
And for playing from A1200 hard drive: I don't know if it's necessary but I ran Bridge Strike after creating this script:
assign BS_1_OF_2: ""
assign BS_2_OF_2: ""
