Arcade Romset for a raspberry pi 4 4gb

Hello everyone, I’m new to batocera, I used RetroPie on my previous setup but I’m looking for some simpler retrogame system.

I was searching this forum for suggestions on a proper romset to use on my rasp 4b without success.

Could you please tell me which emulator/romset is better for arcade games?

On my last RetroPie setup I was using fbneo.

Thanks

For weaker machines, you generally want to use mame2003plus or fbneo. The latest versions of each should be fine.
