Rockman X3 Buster Battle

About

Released it as a pack-in for a version of the console released after the first revision. Unfortunately, it seems the cartridge was not released separately. This package came with both a game cartridge (dark blue) and a manga/design cartridge (light blue) for additional stamps. The game consists of a simple battle feature where you pick a character, draw a weapon for them, and battle various Rockman X3 villains in RPG-like battles.
