Kessakusen! Ganbare Goemon 1 & 2, is a title in the Ganbare Goemon series. It is an action title released on April 21, 2005 for the Game Boy Advance.
Summary:
Kessakusen! is a compilation of the Super Famicom games The Legend of the Mystical Ninja and Ganbare Goemon 2: Kiteretsu Shōgun Magginesu, ported to the Game Boy Advance.
Version Differences:
The Legend of the Mystical Ninja port allows for three saves files, which are created though password entry.
As it is a single player game, the multiplayer and piggyback option is unavailable.
Pressing the select button now allows the player to change character at any time.
Like Ganbare Goemon Kirakira Dōchū, a "Mini Game" option has been added to the start screen, allowing access to mini games from both games. However, some of the mini games in The Legend of the Mystical Ninja are only playable in the main game.
