they announced at the beginning of April that they also have PS1, GBA, and Gamecube ports in the works
not sure how viable “porting the same game to half a dozen different retro systems” is as a revenue model, but they seem to still be around after nearly 4 years of this so idk
(funnily enough though, the SNES is the one major platform (post-8-bit) that i can’t see them producing a port for)
