I always wondered why the Mame Devs never get together and make something like this on classic hardware like Sega Y board hardware or similar. I assume nobody has the time.
All that programming talent would make interesting use of the old hardware I'm sure.
I fantasies about porting/recoding a cool SNES/Mega drive shooter to this powerful hardware. In essence making a deluxe version of the game that the SNES hardware would just not be capable of.
Then again, I don't really have a clue about any of that stuff ha.
