Grego abandoned this project, because Rotwang is working on a two-player hack for Final Fight Guy that added all three characters in it.
You can find his hack by doing a Google search.
Oh, I'm aware of the patch. If it's the one I'm thinking of, I even have a copy. Rotwang indicated that it was still very much a work in progress, but work appears to have stalled entirely and I don't believe he posts here or much of anywhere else anymore.
Was hoping that both he and Grego might consider collaborating on Final Fight SNES again since work on the 30th Anniversary version of the arcade game seems to be largely wrapped up. Or, conversely, that Grego would simply pick his own work back up since it doesn't appear Rotwang is doing anything with the SNES release anymore.
