Mega Man Battle Network 3 Blue ROM

Both versions have identical plots, but distinct qualities unique to each game. White has the standard appearance of buildings and objects, evidenced by ACDC Town's squirrel statue, which is always pink. However, Blue has new color schemes for buildings, and some objects are totally different, such as the squirrel being gold (a color change that becomes prevalent between both game variations in later installments).

This is also the first time different chips can be obtained in separate games, such as unique, one-of a kind Giga Chips, which also becomes the standard among the later games. Giga Chips cannot be traded, but in this game, the Omega Navi Giga Chips are actually duplicated.

In addition, both versions have their own unique Styles that can be obtained by certain conditions. White has Ground Style which is focus manipulating area in combat, while Blue has Shadow Style that have their charge attack make MegaMan become invisible and invincible for a short period of time.

The games also have two separate bosses working with Serenade. White has MistMan, but Blue has BowlMan. As such, their chips must be obtained through NetBattles, not a Chip Trader, and even then, the Mega Chip library isn't complete until the chips of both Navis are traded between separate versions.
