Excellent release! I don't know what it is, but the screen just looks BETTER on my end. I know they added scale2x to the GUI, but the games are much better looking in anti-alias with my Nvidia card. I actually had to delete my old cfg file for it to work correctly (something I haven't had to do in a LONG time), so you may have to do this as well if you unzip it to a previous Zsnes directory.
