To trigger these credits, hold Up + Left on the left joystick, Down + Right on the right joystick, and 1P Start + 2P Start together. If done correctly, a dot should appear near the bottom of the screen.

Let go of the controls, then quickly press Up on the left joystick, press 1P Start, then press Down on the right joystick. After all that, the credits should pop up on screen like space magic.
