@stoo said in Gauntlet and Gauntlet 2 on lr-fbneo possible bug:

Are there titles that don't work with it?

Yeah there are, i don't have a full list but i can mention some :

sega system 24 (you found this one) and probably any other arcade systems using several m68k sega system 18 and megadrive (m68k worked differently on those systems, so you need another version of cyclone which apparently wouldn't work with "normal" 68k games) some neogeo games in mvs/unibios, they seem to work with aes though
