OutRun (Genesis)

Hidden Ending Image
This will only work if the system region is set to Japan, even with the US/Europe ROM (the game is not region-locked otherwise; the region is checked at startup and saved in RAM for later so changing the region mid-game will not work; whether a reset will work is unknown). Get to the ending, either by beating the game five times landing on each goal or by entering ENDING as a high score name. Once the CONGRATULATIONS! screen starts, wait approximately 10-15 seconds, then press A once, B twice, and C seven times. You can press the buttons in any order. If done properly, the screen will immediately change to this one, which shows (most likely) your female passenger in a bikini.
