• Full power up

    Press Start to the Pause Menu and then enter the code.

    Full power up cheat is cumulative. After you use one, it deducts from the total.

    For example:
    At the beginning (stage 1), you have only 1 full power up cheat.
    At stage 3, if you never use it, you have 3 full power up cheats.
    At stage 5, you have 5 full power up cheats, etc.

    You can use these codes on Stage Select mode too, but you cannot use it on Score Attack mode.
