This is not original either, but I have extracted the contents of the ADF images.
Just bought boxed 1.2 on Ebay. Also noticed this set of unboxed BB on 5¼"
, but I'll rather wait for another box. They pop up now and then, but they're usually gone by the time I've seen the mail for the automated search.
The file structure seems quite similar to PC versions, but it seems more stuff is integrated. I wonder if we could port the physics engine part to PC. Probably not.
Anything is possible, besides finding time to do it. Clvn made some impressive progress on restunts before Christmas, so a port of BB1.1 will be ready any decade now.
