would be a guesstimate that you would need to extract them first (using 7zip, winrar, or another such program) before they can be opened with the program (MAME being the only one I know of that reads compressed-format files).

I believe ZSNES reads zipped games as well, but that's besides the point. Yes, you need to extract them first before you can play them as SE7EN already said. :3
