Guilty Gear Isuka and Rumble Fish 2 have now been ported to SEGA Dreamcast » SEGAbits

DCGX says:

I guess it depends on what games you’re talking about. JoshProd got a license to release Visco games on the Dreamcast, which were on Neo Geo platforms originally, but those were not SNK developed games.

Of course, with the Crown Prince of Saudi Arabia taking a controlling stake in SNK, who knows what happens. I mean, my money is on a boycott, but maybe they give someone a license to officially release these Atomiswave ports on Dreamcast.
