I find even with a pi4 i can't run anything past 1080p, also make sure you have your game mode set on your tv.

I will admit i have not attempted to use advmame yet, so i am just kinda throwing out suggestions.

@Kartman Hello, I cannot find a good scanline reproduction with ADVMame. It does not use shaders, only overlays. Tried to make a few scanline overlays and had no luck. There are video options for scanlines, but I could not find anything that looked as good as shaders do.

@mitu I've got it working now, I had a typo in my file, I had missed out the / before dev/input/. Schoolboy error but sorted now. Many thanks for the pointers and your help. Working between my PC and the cabinet is quite tricky. I'll need to get SSH sorted out so I can do the edits from the PC direct.

@dnuno Great build! 👍

That being said, you should try one of the other MAME emulators - Mame2003 has mouse support and RetroArch seems to detect your mouse. As a plus, it supports absolute pointing devices.
