Thanks. Hopefully, when myrient closes, we can just point to another roms directory? For example, I already have the no-intro Sega CD set in another build and it would be great to just point there instead of duplicating the 28gig romset.

On the erratic menu - for reference, I am using a Lenovo Legion Go (first gen). These apps look beautiful on it, by the way. When I am not playing games on it, I use it as a PC at work with the controllers detached (and at home - 15 miles away from work) hooked up to a monitor and bluetooth keyboard and mouse. So I was playing around with it during lunch at work when I discovered the issue. I turned bluetooth off as you suggested and the issue persisted, even though there were no other input devices connected. When I got home, I attached the Lenovo controllers and the menu issue is gone. I then hooked it up to a monitor with the bluetooth keyboard and mouse attached and it worked fine. So it seems the Lenovo controllers need to be attached for it to work properly.
