If you have Sonic & Knuckles, you can access a special bonus stage. To activate, insert your Sonic Spinball cartridge into Sonic & Knuckles, then turn on your Genesis. Wait for a screen with Sonic, Tails, Knuckles and Robotnic and the words, "No Way". Now hold A + B + C and you're ready to play.

Note: These codes represent the original SEGA Genesis controller button layout. Your Wii Virtual Console input device will reflect different button names.
