Hi there!
I've been playing amiga games with UAE for two weeks now and I just can't find out how to save a game. When I want to save e.g. monkey island it says "insert save disk" then I push F12 and experiment a bit with blank adf files, but it didn't work yet. I would be very grateful for a sollution to this problem.
Thank you!

you need a formatted blank disk, you can't just create a adf and expect it to work. also some games require special savedisks, go to http://www.back2roots.org and there you can find formatted blank disks and savedisks for specific games.
