Cave Story Cheats

Once you get to Curly and beat her in the Sand Zone, avoid trading your Polar Star for the Machine Gun. Later in the game, you can trade it for the Spur -- the strongest weapon in the game.

Enter the following codes on the Title Screen for the desired costume. You should see a message saying "Press the A Button to Begin" after entry.

Play the game on either Christmas Eve or Day (set the date to December 24th or 25th on your Wii), and Quote (on any difficulty) will have a black face, green ears, and don a Christmas hat.

While on the title screen, hold the B button and enter one of the buttons combinations below to change Quote's appearance. If entered correctly, the "Press the A Button to Begin" message will flash. The codes will work for any difficulty setting.

If the Wii's date is December 24 to 26 (set in thw Wii's settings), the appearance of the character in Cave Story would change into a Christmas/Holidays costume (regardless of character selected). The character and his/her costume will be in-game and in the menu.

After you've talked with Chaco about the Jellyfish Juice, rest in her bed. You'll wake up with Chaco in it and her lipstick in your inventory.

If you grabbed the Map item on your way through the Mimiga Village, you can use it in the back room after fighting Curly in the Sand Zone. Doing so will reveal a secret passage. If you use the map to navigate to the end and onto the ledge on the left, you can use the "Look" button to pick up Curly's Underwear. They serve no purpose.

Perform the actions below to unlock different endings.

The Machine Gun can be used as a "jet pack" when its at Level 3. Just jump and aim it downward to float up until your ammo runs out.

Only applies to the updated version; they are unlocked from the start in the original release.

After making the rocket that leads you to the last cave, do NOT talk to Momorin to get your booster back. Instead just take the rocket and keep your Mimiga Mask. There will be some dialog change after this point and some of the portraits displayed during the credits will be altered as well.

(This should only work on the update or European version) From the Options menu, highlight the music option (Not the volume, the one with the New/Old option) and press 1 to go forward, 2 to go back. While the music is playing you can switch between Old and New to hear the original version or the New version.
