8 Eyes
Japanese version:
(GEN) Sound test:
Pause the game, and you can use controller 2 to scroll through the tracks with Left or Right and play a track with A. This cheat actually should've been enabled by the button code during pause A + B on controller 1 and A + B on controller 2 at the same time, but by accident, the cheat enable flag was overwritten with some system variable and in this particular place always non zero, so this cheat is always enabled automatically, when you enter the pause mode. In the US version this cheat was removed completely.
