Can we have demul emulator group? Like FBNeo group.

While Demul is not perfect, it is much better than mame and fbneo. Can we have the option to play Demul games? Currently, cave demul is not supported.

Which system do you want to play with Demul ?

Seems to me, all demul supported games are better on demul except dreamcast. Also, alternative to demul, flycast does not have the compatibility like demul have.
System like naomi, naomi 2, hikaru, gaelco, atomiswave, cave works on demul.

Yes, but it's actually the case.

You can use demul for them (only Cave is missing, but fbneo or fbalpha have great results)
