Mega Man Battle Network 3 Cheats For Game Boy Advance

  1. Secret Boss

    After you complete the Secret Area by defeating Serenade, put at least 300 BugFrags in the Trader, then leave the internet. When your return to the Bug Trader, Forte will appear, fused with Gospel, and attack you. If you defeat him, you will get the Forte chip.

  2. Secret Area

    Once you complete the game by defeating the final boss, wait until the credits roll and the title screen appears. There should be a star next to 'continue'. When you continue the game, it will continue from the spot where you last saved as usual, but you will now be allowed access to the Secret Area, which is located in the Ura-Internet square. You can only get there by pluuging into the computer under the hot springs. You will need 100 standard chip entries in your library to enter.

  3. 300000 Easy Zenny

    First do the job "Legendary Tomes". Once you have the tomes don't go back to the Navi, instead go to the teachers lounge. Look at the back shelf and examine the strange orange statue. Theres a code in the statue that matches with the tomes and the data is 300000 zenny.

  4. 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.

  5. 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.
