nah i dont like snk.

batocera is really simple. much simpler than my old retropie set up.

you just flash it to a usb stick and then plug the usb stick into your device (you might have to go into the bios to change the boot order so usb is 1). that's it. you can even get premade images with roms included if you don't want to set up your own:

then when you unplug the usb stick, the device returns back to its normal state

scrape your game list inside batocera to automatically download videos and art (the arcade scrapers are free)

better to add the roms yourself. you can get them on archive.org ("FinalBurn Neo (v.1.0.0.2)") and cut it down to just the best of the best so you're not scrolling through 10,000 games. also that way you'll have the latest version of batocera os. and remember to download the bios files and put them in the bios folder.
