Cotton 2

Complete the game under the hard difficulty level. Then, choose the new "Pad-XYZ" selection that appears on the option screen. Note: Set the XYZ controls to "Command", then press L or R to fire command shots. Pressing L fires a small bomb.

At the title screen, select the option screen menu. Now press and hold ABCXYZ buttons at the same time (press A a split second before the others). You should now be in the option screen with some additional choices.

This will let you select Appli and Cotton as player 1 or 2, access music test, and even has some control options for XYZ buttons, including rapid fire or single button moves!

Back on the main menu there should be a Training menu as well.

Hold Up + Start + A before entering level 1 to use all three magic types simultaneously. Press A for Fire, B for Ice and C for Wind.

Hold X + Y + Z then press and hold A + B + C at the title screen. Keep all six buttons held to unlock an extra selection on the options screen and a training mode selection at the title screen.
