Yoshi's Cookie is a puzzle game in which you help Mario and Yoshi run a cookie factory by rotating rows of cookies until they form a row of identical cookies and disappear. It's a great way to spend a long car trip if you're burnt out on Tetris and/or Dr. Mario.

Debug Screen

A debug screen is present at 0x18001 in the ROM. It can be activated with Game Genie code 001-DFF-A2A (001-CCF-A2A Yoshi no Cookie) or by replacing ROM address 0x01DF with 0x00.

The "HERMETICA DEBUG MODE" text dates this menu to the game's early development as a non-Mario game titled Hermetica. Setting SPEED to TEST will cause the accumulation rate of the cookies to stop until B is pressed or held; releasing B will again cease movement of the cookies.

A similar debug menu is present in the NES version.
