These are rom files. In order to unzip them you'll need winzip. If you want to run it you'll need an Emulator. Remember, that having rom files on your computer is illegal for any amount of time, so downloading these are purely your own actions, and i can't be responsible for your downloading them. Note:All of the ROMS have faqs/walkthroughs at Gamefaqs. I will ignore any e-mails regarding help in a game.
