Megamari [cheats]

Enter final stage with no weapons except Magic Broom
If you think the game is too easy, you can put mushrooms in all 25 slots on the password screen to access the final stage with none of the special weapons except the Magic Broom, which is required within the stage.

Passwords for the final stage
Enter one of the following possible passwords to access the final stage with the weapons/items described. Unless otherwise stated, Marisa will have weapons from Sakuya, Remilia, Yuyuko, and Reisen and Alice will have weapons from Reimu, Cirno, Youmu, and Eirin (My recommended weapon combination)

Note that passwords giving Mega Tanks, which completely restore all health and weapon bars, are hacked, since there is only one of them in the game and it cannot be obtained until the final stage itself (It will never be in a password generated by the game).

To make these work, put mushrooms on all of the slots described on the password screen.
