Yoshi
Also known as: Yoshi no Tamago (JP), Mario & Yoshi (EU) Developer: Game Freak Publisher: Nintendo Platform: Game Boy Released in JP: December 14, 1991 Released in US: June 1, 1992 Released in EU: December 10, 1992 This game has unused enemies. This game has unused graphics. This game has regional differences.

A portable black and white version of the NES game.

Unused Graphics

The top of Baby Yoshi's egg, meant to be used on the title screen (as seen in the Famicom version).

Unused Bullet Bill Enemy

Game Genie code 059-0CE-E6A will enable a nearly completed Bullet Bill as a fifth enemy piece. It is fully functional, though it will turn into garbage when it settles on the playfield, as its graphics were overwritten (specifically, with the bottom of the "A TYPE" text). It is possible that the game was considered insidiously difficult with five enemy pieces.

Neither the extra piece nor its graphics are present in the NES version.
