I also used winuae forever but started to yank the controls and suddenly.....
I think the winuae follow the windows size then nullfilter is chosen in the filter tab. This is when resizing a windowed winuae. For the desktop test above I had to go back and fourth a couple of times between standard and borderless to find the right fit. (It cant be resized when borderless is chosen. Nothing to grab onto.)
The other thing with fullscreen, filling the empty sides can probably be done with this Overlays.
Make a folder inside the winuae folder and call it "Overlays".
Put a suitable png pic inside and it will show up when you choose Overlays in the filter tab and then to the right of that choose the pic.
(I had to make a new config from the start for the Overlay to be present.
Then all controls underneath in the filter tab is to make the size and position to fit in the ”Overlayed” pic.
Here is a pic on settings I use for the Overlay with fullscreen on the second pic link above.
Hope this helps. It would be nice if a winuae expert could put together some guides.
