I’m aware it was created as an April Fool’s joke, but considering it really is bSNES (albeit outdated) and does use ZSNES-alike hacks, and is open source, is there a chance for such a core for RetroArch?
It’s been discussed but no one has verified if it actually has greater compatibility with ZSNES romhacks. Even if that pans out, I don’t think anyone really has much inclination at this point.
So, to answer your question, it’s not likely unless someone comes up with a compelling reason.
