Yoshi Sample

Developer: Nintendo
Platform: Game Boy Advance

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 been released.

Nintendo supplied Yoshi Sample with each Game Boy Advance development kit as they started to dole them out shortly after the system was first shown in April 2000. It is a scaled-down, one-level port of Yoshi's Story with much more 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. Notably, a few of the enemies featured in Yoshi Sample did 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/file differences.
  • Look into Version 1's origin.
  • Unused Killer bmp?
  • Unused code and/or files?


Debug Features

Button Function
Start CPU Speed Check with egg graphics on left and right of screen.
Select Causes Yoshi to lose 1 petal of health.

Source Code


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


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

Yoshi Sample-bomb.gif
"bomb". 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 looks nothing like any Bullet Bill in any released game.

Yoshi Sample-omori5t.png
"omori5t", a 5-ton weight.

Version Differences

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

Build 1 Mute

Has no sound, but nonetheless contains sound-related code and files. Its origin is currently unknown.

Build 2 Sound

Aside from having sound, the sound-related code and files are different than those in the above build. It was bundled with the third version of the GBA's SDK.
