In the "System" submenu under the F12 setup menu of Hatari - the screen where you define the machine type and a few other parameters, there is a 'Video Timing" option which can be set to either'Random' or "Wakestate" = 1 through to 4. I can't remember noticing this option pre-Hatari V2, so I assume (perhaps incorrectly) that this is something which is new in Hatari V2.
What is the purpose of this setting?
Under what circumstances would we choose to set it to WS=1, or WS=4, or strangest of all, 'Random'?
Also in the new SDL2 options section of of 'Hatari Screen Options' it would be good to have an 'aspect ratio lock' checkbox so that if, in windowed mode, we drag the window bigger and smaller, the emulated screen will maintain the correct Atari aspect ratio (4:3?) whenever the user alters the X width or Y height or both at the same by dragging one side or one corner of the window.
(So if you pull the window wider, the window also becomes proportionately taller to keep the aspect ratio correct. If you pull the window narrower, the height also decreases to maintain the window at the correct aspect).
