Yoshi's Story

Yoshi's Story is a super happy game where everyone is super happy! <3 <3 <3

Test Levels
These test levels can be entered by using the US GameShark code (replacing XX with the respective level ID) and entering into a level in the time trial level screen while holding the GS button. You can see them in action here.

Jump Height Test ()
The level's layout merely tests to see how high and/or far Yoshi can jump. Sideways numbers indicate the distance up from the ground, while the straight numbers indicate the distance between the floating platforms above. At the top of the pause screen, it will say "ないデータをよもうとした", which translates to "Tried to read nonexistent data".

Cogwheel Test
A test of the Cogwheel platforms.

Cloudjin Boss Test
A test for the Cloudjin boss and see-saw platforms.

Unused Music
This track sounds like the tracks that play when you open one of the pages in Story Mode, but it is never used.

Crash Debugger
A crash screen identical to the one in The Legend of Zelda: Ocarina of Time is present in this game. To access it, enter the following GameShark code:

When the game crashes, press L, R, Z, Up, Down, Up, Down, Left, Left, Right, Right, B, A, Start to access it.

Debug Mode
Enable the Gameshark code in the Japanese version to open up a menu.

'!' means 'not' in C/C++, so '!0' here likely means "if not zero".
 * Debug Registers 0
 * Z+left to go away

Options menu and Story save
The Japanese version didn't have Story Mode save feature. For this reason, the option to erase Story Mode's save data is absent in Japanese version.



Story Mode (Continue From Page 2) Trial Mode Options Practice

Oddly, the Japanese mode of US version has the fully translated "Start From P.#" banner, complete with unique font.

Also, when data is erased in the Japanese version, an explosion can be heard. In the US version, it plays a fanfare.

Secret Coins


The secret 'Y' coin in level 1-1 that appears when Yoshi eats the heart fruit is absent from the Japanese version.

"Play other levels in Practice Mode" glitch
Japanese version has a glitch that allow the players to play any level from the first world in the Practice Mode. In international versions, this glitch is fixed. To do this glitch, at least one level must be unlocked in Trial Mode.


 * 1) Go to Trial Mode.
 * 2) Enter any level. (This sets the "Yoshi is alive" flag to all non-green Yoshis)
 * 3) Exit the level by Z+Start.
 * 4) Go to Practice Mode.
 * 5) Die.
 * 6) In the death cutscene, press Start button. This will bring up the retry menu. (This is possible because the non-green Yoshis are alive)
 * 7) Selecting "Yes" will bring the players to level 1-1. Selecting "No" will bring the map screen of the first world, allowing the players to select any level from said world.

The pause screen behaves like Story Mode; The players cannot escape the level. However, completing the level will bring up the score tally of Practice Mode, and the game will reset to the main menu.

International versions fixed this glitch by resetting the "Yoshi is alive" flags when starting Practice Mode.
