You know I had no idea there was differences between formats but now you have me curious. It is obviously through emulation and is a regular SSD file, so at this moment in time just looking at the game it I am unable to answer that question. It would take some time to be 100% sure as I would need to make a map lol.
You have me interesting in probing two versions of JSW2 if I have them.
As far as I'm aware the 'cut down' one would of been tape only originally. Obviously they are all SSD's now. The 'disk' version is larger and loads sections as you go along. For instance in the disk version moving from 'First Landing' to 'To The Kitchens' causes a disk read. The 'tape' version moving left from 'Macaroni Ted' takes you to the 'Fallout Shelter'. On the 'disk' version that 'Macaroni Ted' screen is awol its 'Bathroom' straight to 'First Landing'
There are other differences, the JETSET WILLY message is solid in one and pixelated in the other.
Really a good map of both versions is needed.
Here's two structure screenshots:
Note: The disk version will crash horribly if there's not enough memory (or sideways ram not checked) I had to scale it down to just OS/DFS with ADFS present (but disabled) and a DNFS rom it crashed. See my 'suggested' basic config:
I think a new topic for the B versions of JSW2 is in order however, if you wanted to make one I'll chip in bits and pieces etc.
