We could only wish we were playing this right now... maybe...
This game was never completed and/or given a public release.
As a result of this, keep in mind that the developers might have used or deleted some of the content featured here, had the game actually reached store shelves.

Nintendo supplied Yoshi Sample with each Game Boy Advance development kit as they started to dole them out shortly after it was first shown in April 2000. It is a scaled-down, one-level version of Yoshi's Story with much simplified gameplay and no ending.

It was created to show off the capabilities of the GBA, featuring colorful pre-rendered sprites and a 2.5D environment. A few of the enemies featured in the demo do not appear in Yoshi's Story.

To do:

In order of importance:

  • Host on TCRF before everything goes boom?
  • Install SDK 2.0
  • Build source code, check diffs with included build (how?)
  • Build Dates
  • Sound Code/Files Diff
  • Version 1 Origin
  • Unused Killer bmp?
  • Unused Code, files?
  • blargghb


Debug Features

Source Code


The ELF file appears to contain more names from the source code, though this does not effect the gameplay.


The two unique enemies that don't appear in Yoshi's Story are internally named:

Yoshi Sample-bomb.gif bomb. It has longer legs than most Bob-ombs.

Yoshi Sample-killer.png killer (bullet-bill's Japanese name). Has a lot of frames that appear to be badly drawn, and it looks nothing like any Bullet Bill in any released game.

Yoshi Sample-omori5t.png omori5t (weight 5 ton).

Version Differences

Elementary, my dear Cactus.
This needs some investigation.
Discuss ideas and findings on the talk page.

Build 1 Mute

This one does not have sound, and has different sound related code and files. Its origin is currently unknown.

Build 2 Sound

This version does have sound, and has different sound related code and files. It was bundled with the 3rd Version of the GBA's SDK.
