Mega Man Battle Network 4 Blue Moon Codes and Passwords (GameBoy Advance)

MegaMan Battle Network 4 is the fourth game in the MegaMan Battle Network series. Like Battle Network 3 before it, Battle Network 4 has two different versions, Red Sun and Blue Moon that differ only in minor story and gameplay details. Battle Network 4 is compatible with the e-Reader and can be linked up with Real Operation and the Battle Chip Gate for NetBattles, they are present in the English versions. Battle Network 4 greatly differs from Battle Network 3 in many ways, the most notable of which is the concept of DoubleSoul (Soul Unison in the original).

DoubleSoul is similar to how the classic-style Mega Man could acquire the weapons of the Robot Masters that he has defeated: by using DoubleSoul, MegaMan.EXE could use the powers of other NetNavis in the same manner as how classic Mega Man could use the powers of the Robot Masters through their weapons. To perform a DoubleSoul, which lasts for a temporary amount of time (three turns), however, a chip must be sacrificed for the battle. Another key feature is that it takes a minimum of three playthroughs of the game's main story mode in order to uncover all of its secrets - although many criticize the game for the same reason.
