Alyosha, aren't you interested in creating an Atari Jaguar emulator at all?
There must be one or two emulators that don't work too badly, but that's all...
Same thing for the 3DO...
Or help to finish CPChawk and/or the Fairchild Channel F emulation?
Or a CD-I emulator? Or an equivalent of Atari800/Altirra?
Or GX-4000, or Amiga CD32.
There are so many "obscure" consoles, portable or not, which do not benefit from a correct emulation...
Watara’s SuperVision etc..
Another thing that would be interesting would be an Emerson Arcadia emulator (there is
https://amigan.yatho.com/ which is really quite good already).
Or for the joke an emulator for the Bandai Playdia, the N-Gage (that's a real challenge I think) or the Apple Bandai Pippin...
Or indeed a Xbox/Xbox360/Xbox One emulator! 😂
Or.. ultimately... finaly a good Dreamcast emulator! Or Amiga emulator indeed...
(I wonder, by the way, how complicated it would be to waterbox Redream, nullDC , Chankast, Reicast, DEmul, DreamEMU or Icarus , even if the best would be Redream I guess)
