  • The Mummy (GBC)

    Mummy, The (U) (GBC) & Mummy, The (E) (GBC), Hamunaptra: Ushinawareta Sabaku no Miyako (J) (GBC)

    I could likely figure out what this cheat does, if I felt like playing the game, but until then:

    Unknown Cheat
    At the Main Menu, press Select, Up, Up, Down, Down, Left, Right, Left, Right, B, A. A sound effect will confirm proper entry. For the Japanese release of the game, the Select button is not needed.

                • Five Extra Lives Cheat - Looney Tunes (U) (GBC)

                  Looney Tunes (U) (GBC)

                  Five Extra Lives Cheat
                  At the Title Screen, press A, B, B, A, Select, Select. You'll hear a confirmation sound and will start the game with 7 extra lives instead of 2. This same cheat will also work on the original Game Boy release of the game.

                  • Cheat Mode - Magical Chase GB: Minarai Mahoutsukai Kenja no Tani e (J) (GBC)

                    There is another push-button cheat for the following game, but I've had no luck figuring it out. If anyone else would be kind enough to decipher it, that would be cool. The Japanese Game Boy Color game is called Magical Chase GB: Minarai Mahoutsukai Kenja no Tani e. Here is the already known cheat, and it's effects:

                    At the title screen press Up, Down, Up, Down, B, B, B, B, Left, Right, Left, Right, A. Then on the next screen a new 4th level select option will appear at the bottom.

                    New Option:

                    Stage Select:

                    That cheat uses 13 buttons, and I believe the new cheat is 17 buttons.

                    Here will be the effects of the undiscovered cheat:
                    New option has a + beside the words:

                    Invulnerability, and 99999 Orbs options added to the Stage Select:

                    GameShark Code:
                    Cheat Mode
                    Note: A new 4th option is added to the Main Menu. Inside the menu is an option for Invulnerability, 99999 Orbs, and a Stage Select.

                        Note: You may need to have two Game Boy's linked together to actually play the mini-games, since I was not able to play them otherwise.

                          • Monsters, Inc. (UE) (GBC)

                            Monsters, Inc. for the Game Boy Color contains some disabled passwords, one of which is a Stage Select. It's disabled since the password is AAAA which is impossible to input. Here's a Game Genie code to change the password to BBBB to re-enable the Stage Select.

                            Monsters, Inc. (UE) (GBC)

                            Stage Select
                            Note: Changes the disabled AAAA password to BBBB.


                            Attached is an IPS patch to re-enable all the passwords, here is the full list of them:

                            The passwords in brackets will work after patching the ROM.
