Editing Yoshi's Story (section)

===Game Boy Advance tech demo===
When Nintendo unveiled the [[Game Boy Advance]] to U.S. game developers on April 10, 2000, one of the available demonstrations was a [[tech demo]] derived from ''Yoshi's Story''.<ref name="techdemo00" /> It was specifically developed to show off the Game Boy Advance's graphical capacity, featuring an opening [[Demo (computer programming)|demo]] and a single looping course. The opening displayed a pre-rendered rotating island, resembling the shape of a Yoshi, taking advantage of the system's affine rotate-and-zoom feature (akin to the Super Nintendo's [[Mode 7]]) to render a seascape in perspective.<ref name="techdemo01" /> The demo's level design was based on the colorful cardboard theme of ''Yoshi's Story''. However, the gameplay differed significantly from the original game. For instance, Yoshi was unable to use his tongue; nor could he throw eggs, in spite of being able to obtain them. Screenshots from the demo show the presence of giant Shy Guys, that were primarily designed to demonstrate system's advancement from the [[Game Boy Color]]'s 10-pixel sprite limit.<ref name="techdemo03" /> In spite of the fact that Nintendo had published a promotional image of a Game Boy Advance with the tech demo running on it, it was never released as a completed game. The tech demo has been salvaged and showcased its functionality as a game.<ref name="(UNRELEASED) Yoshi's Story 2: GBA Tech Demo" />
