So awesome to see this -- thanks!! The demo worked smooth, but there is one major problem and I'm not sure if it's the program or on my end. Any option off the Gray Hatari menu takes like 30 seconds before it registers input, so it's kind of near impossible to deal with at this state. Looking forward to a fix as this is going to be one helluva an emulator. The Atari ST had tons of great software/games.
Also: I somehow got a white menu that popped up and can't figure out how to get it back. It looks like initial settings? That menu had no problems (I just can no longer access it).
