First off download and install Chankast. You'll need a BIOS file to run the emulator, and before you even think of asking for one, don't. It is against the rules to ask where to download BIOS files, game images and stuff like that. Download and install Daemon Tools 3.29, run it and configure a virtual drive. Also configure Chankast to use that drive and also set up other options like controller layout. Mount an image onto the virtual drive through Daemon Tools. Run Chankast and tell it to run the game.
