Hey I took a quick look at your files.
What's your monitor by the way, a VGA one ?
1st things 1st, you have waaaay too many resolutions in your crt_emudriver.
Make sure you deselect mame.xml when using vmmaker.
You only want to create resolutions from your ini file (aka super resolutions retroarch or whatever it is)
Next in Attract Mode, choose fill option and enable resfix to redraw the frontend upon exiting the emu
Here's a quick video with these settings
EDIT : OK for whatever reason, I can't seem to make the yt video embed in the post.
Oh one last thing that occurred to me is "maybe" (mark the quotes) since you use 640x480, it fails to revert back after switching to progressive super res. Take it with a grain of salt, I'm not sure on that part as I run a 15khz only monitor.
Let me know if it worked.
EDIT2 : I managed for the video, good for me !
Ate mais tarde
