It’s got its niggles, but it’s a very good copy of the BBC Micro original — I took a look at that again to compare. I’ve found myself wanting the original keyboard controls, and may go ahead and reconfigure it to match.
While playing around with the BBC version (actually the slightly-enhanced Master version) I refreshed my memory of how to dock without using a docking computer. I was a bit rusty, but managed to do it without too much trouble. (Well, okay, it was actually my second attempt — BeebEm includes an option to record output to an AVI.)
