Yoshi's Story (tech demo)

The Yoshi's Story tech demo was created in order to show off the capabilities of the Game Boy Advance. It was modeled heavily after the Nintendo 64 video game Yoshi's Story, featuring nearly identical graphics and gameplay. In the tech demo, the player controls a green Yoshi and navigates through a stage, defeating typical Mario enemies such as Bullet Bills, Shy Guys, and Bob-ombs. Like in Yoshi's Story, the color of the Shy Guy would change when Yoshi performed a ground pound. There were also super-sized Shy Guys that would shrink when stomped on.

Before the tech demo started, the player would see Yoshi's Island rotate, showing off the abilities of the GBA's .AMI FMV. It was reported that the game was just a tech demo, though some speculated that Nintendo would create a full game as they did with the "tech demo" of Super Mario Bros. on the Game Boy Color.
