Meant to be a revised version for bug fixes and whatnot, Rockman.EXE3 Black was released in Japan some time after the initial EXE3 was released. Black was released internationally as Battle Network 3 Blue and regular, no-color EXE3 is known as Battle Network 3 White internationally. There are many differences between the two, such as an exclusive battle against Punk in Blue/Black, different color schemes for buildings and objects (the squirrel is ACDC park is an example), different Giga Chips, and Style Changes exclusive to each version.
