Play Momotarou Densetsu Gaiden (Japan) on gb Online

Momotarou Densetsu Gaiden is a 1991 Game Boy release from Hudson Soft, a side story in their long running Momotaro series. It arrived during the handheld's early years, when developers were still figuring out how to fit a full adventure onto that small, green screen. You play as the peach-born hero, Momotaro, on a quest to defeat the demon lord terrorizing the land.

You control Momotaro directly, moving screen by screen through an overworld, towns, and multi-level dungeons. Your main objective is to gather the legendary Regalia by exploring and solving environmental puzzles. Signature mechanics include recruiting animal companions, like a dog, monkey, and pheasant, who each assist in combat with their own special attacks. You engage in turn based battles against oni demons, using swords and magic, and the pacing can feel slow due to frequent random encounters. It feels like a condensed, portable version of an 8-bit console RPG, complete with all the grinding and exploration that entails.
