cheers for trying anyway mate. Yeah, I think the only way would be to use some special tools and an Amiga to get a "clone" type dump, including the protection etc.
I saw a thread on the English Amiga Board regarding the SPS, (Software Preservation Society), and I think they use their own "IPF" format? Anyway, from what I could gather, they send you some special tools, and step you through how to dump images etc. Sounds like a lot of effort! Shame nobody ever bothered cracking the Acorn version of Sensi.
Anyway, thanks again mate, appreciate your reply.
