Bummer about GOG. There's some gems I encountered on Steam that aren't on GOG, so I guess their standards do cause them to miss out.
As for the SNES version, if its all that's left, then it's sounding like you're far along.
Yeah! We're at the beta phase and are just working out the bugs and tweaking some stuff. I'm hoping it's finished very soon!
Hopefully there won't be anything too problematic.
