There’s a big tab on the linked wiki page literally saying which romset is needed for each emulator …
And the wiki also says to put your fbneo roms in the fbneo folder and your mame roms in the mame folder.
“I use libretro/mame emulator as default, and fbneo on others. This works for some games, but most might not load or freeze” which is exactly what you should not do. this doesn’t work.
