Last time I tried using newer versions of bsnes, the GUI is too lacking to make any use of it. The folders thing is silly IMO, and the new Higan right now copies the entire ROM file and creates its own save files where it pleases. To me this is rather annoying and non-user friendly. I find that SNES9x has too many glitches with Windows (fullscreen not working properly, file association, and downright crashing even with current Direct X installed) and ZSNES is the SNES equivilent of Nesticle, OLD AND OUTDATED! I've been using BSNES v073, the LAST version to use its old GUI and it runs perfectly fine on my machine. You have to tweak its settings to your liking, but I've had no issues with it.
