Press and hold down OPT1 and UP before the title screen appears get into "freak out" mode. Or at the "Continue?" screen, after the first "beep" of the countdown, and while the timer still shows a 9, press UP and OPTION 1 at the same time, and hold them. You'll see the GAME OVER screen, but keep holding them. The TOKI demo will appear... keep holding UP and on OPTION 1. After the names of the designers fall down, the demo should go psychedelic!! The demo will cycle through colours, a catchy tune will begin, and the pad will allow you to sample digitized TOKI sounds... furthermore, pressing DOWN and LEFT repeatedly will cause the samples to descend in pitch. Conversely, pressing UP and RIGHT repeatedly will cause the samples to ascend in pitch. Note: Once the new demo begins, release UP & OPTION 1. Then use pad to sample sounds. Pressing A or B starts the game normally.
