Thought I'd put this as a news article on it's own as it's a new day, an' all. Dunny has release v0.622 of the Spin emulator. Fixes since yesterday include sorting out screen corruption when switching models, some keyboard issues, changes to +D emulation so it should work with a 128k, and shortcuts are now listed in the menus in more places. There's also a handy "shortcuts" textfile so you know what to press and when.
Lovely.
