Mega Man Battle Network 4 Blue Moon Cheats For Game Boy Advance

  1. Secret Boss

    To get past the gate in Ura Internet area 5, you need all 150 regular chips. Once you get past it, you can fight the secret boss, Forte, and get his chip, Forte Another.

  2. Secret Dungeon

    There is a large hole surrounded by purple slime on a platform in Ura Internet area 6. In order to approach it, you need the chips ''Bug Curse'', ''Muramasa Blade'', ''Black Wing'', ''Element Dark'' and ''Poison Anubis''. Once you get close enough, it will suck you down to the secret dungeon, Black Earth.

  3. Secret Boss SP

    After defeating Forte in Ura Internet 5, Forte SP can be randomly encountered in Black Earth 2. He can drop Delta Ray Edge in Blue Moon, and Black Barrier in Red Sun.

  4. Secret Boss: Duo SP

    One more thing to add:

    To fight Duo SP, you need to have all the 7 symbols

    1 for Duo
    1 for Soul Complete
    1 for Standard library complete
    1 for Mega Library Complete
    1 for Giga Library Complete
    1 for P.A. Complete
    1 for Forte SP

    Go back to where Duo was and fight him there!

  5. Avoid Random Battles (JP Version Only)

    To avoid random battles, save your game about every 20 steps. This will reset the game's random seed, which also resets when your next random encounter will be. Now you can go through the entire 'Net without running into a single fight, or resetting your system because you got into a fight!

  6. Woodman and Nintendo DS glitch

    You need the Blue Moon version for this. If you play the Woodman story on a DS, you will encounter this glitch. When you jack-in to the Park Area and Woodman attacks you, go into a random battle. Run away or delete the viruses. The screen will turn white and freeze. The only way to stop this glitch is to play the Woodman story on a Gameboy Advance SP or on a regular Gameboy Advance.
