Nin, thanks! PM sent.
Actually John I pretty much had your site open the whole time I was setting up the system. Great resource there. I'd say it's invaluable for anyone setting up a multi-emulator system with Mamewah as a FE. Since I followed your links to get the emulators I think I probably have the recommended version. If I'm just missing something... well, I'd be interested to see how you managed key remapping in FCEU As for zsnes I don't see how it's possible without a hack since when you remap a key it uses ESC to clear so you can't really define it as anything.
