Glitches

  • Invis effect in Thunderman battle.

    When fighting Thunderman, when one of the clouds is about to move on a pannel near you (when it's about half way on), move onto the same pannel. The game recognizes it as hit, but you don't take damage. If done right, you should have the Invis chip effect for about 1/4 of normal time. This is a useful trick for S ranking him.

    Multiplayer Chip duplication
  • Requirements:
    2 GBA/SP
    2 MMBN2 game paks.
    Link cable

    This glitch allows you to duplicate your lost chipdata in a netbattle against your oppenant, do not worry about it damaging your gamesave, I have done this hundreds of times and my gamesave has not suffered.

    You and your friend (or just you on your own, still possible to do) must go into network and compete in a real netbattle against eachother, and one must win without flaw, when the battle is over, as soon as the chip datas name is shown, the LOSER must reset his game. (A+B+Start+Select), as a result, where the winners data is saved and the losers is not, the losers chip data is not lost and the winners is still saved resulting in a duplication of the chip.

    WARNING: If the winner resets, instead of duplication you will simply DESTROY the chip, because the loser still loses and the winner doesn't save the fact it was won.

    What are the benefits to this? Well in short, imagine how easy it'll be to duplicate and share your secret chips, Bass V3s, Lifeaur3s and other rare only get one of me chip data. You can even duplicate the final chip data, Sanctuary. Of course the better the busting level, the better the chip you'll duplicate.

  • Zero HP

    Put a ZeusHammer into your folder. Go into battle and take damage on purpose till you have 200HP or less. Then kill the virus or escape. Now, find a Mole2 Virus in WWW Area 3. (This can be done with Mole1, too, but it's harder.) Attack the virus till it has 200HP or less. Then use your ZeusHammer. The Mole2 is deleted and you take 200 damage. Your HP is reduced to zero but you still win the battle. Now you can walk around the net with zero HP.

    Note: Have a healing subchip or you'll get deleted when next battle starts.

    • Secrets

      • Unlock Hubstyle

        To unlock this special style, you must defeat all V3 navis (excluding Bass) with an S-rank. Then, the next time a style change occurs, you will get Hubstyle.
        Hubstyle is a unique style that is non-elemental, and combines the benefits of every other style in the game. It will halve your max HP though.
        This style will only show up once per game, so if you skip or erase it, it will be gone for good.
        To confirm this unlockable, talk to the girl in ACDC Town behind the trees near the park. She will tell you which V3 navis you have defeated with an S-rank, and say that she sees all the available "ghosts" if you have defeated them all.

    Glitches

    • 11th Chip Trick

      This trick will allow you to use the 2nd chip in your folder at any point in battle. First, you need Custom Style to fully level up, then get another Custom Style and begin leveling it up. You need enough Custom+ NaviCust programs to total Custom+5. Install said NaviCust parts. Now, in battle, load up any chip, then hover the cursor over the 10th chip and press right. The picture will show an ''11th'' chip. Now, there are two ways to go from here. If the 11th chip can normally be selected with the chip you've currently got selected, you can select it now and the chip in your first slot will become the second chip in your folder (the second chip in the list when viewing the full contents of your folder). If the 11th chip does NOT match, you can also deselect the selected chip(s) and select the 11th chip. Instead of getting the 11th chip in battle, you will get the 2nd chip in your folder! Really useful with the 2nd chip being a ProtomanV5 chip, etc.

       

    • Chip Duplication

      In 2-player versus, the game can be fooled into copying wagered chip data, allowing players to duplicate chips. This glitch works in both versions.

      First, start up the game and begin a Real match, in which the winner gets a chip from the loser's pack. Once the battle is over and the Battle Result screen appears, the winner must press A once to reveal the chip he just won. Once the chip is revealed, the loser must turn off his game without pressing any buttons. This will let the loser keep his otherwise lost chip while still putting it in the winner's chip pack, duplicating the chip.

      Make certain that the loser is the one to turn off his game; if the winner turns off his game, the winner will not keep the chip while the loser still loses it, destroying the chip.

       

    • Walk Through Navi

      In Secret Area 2, near a warp point where the Time Trial Navi is standing facing diagonally down to the left, you can go into the corner behind him. If you press down at the right spot, you should walk through him.
