Note 1:
The Code Is Beta, because it Only works when you have already grabbed a superstar.
Pressing Select+Up Will Set The Halfword to A000.
Pressing Select+Down Will Revert Back To Normal Yoshi.
I have been trying (Not Sucessfuly) to work on using this effect WITHOUT the need to touch a superstar, but just can't seem to find any solution.

Feel free to modify The code to be able to go into superstar mario (without touching a superstar) by pressing Select+Up.
Just Make Sure to credit Me for creating it, and credit yourself (If You Want to) for editing it.

Note 2:
Use the "Press Y+Down to go down 2" and "Press Y+Up to go up 2" codes and go to the Museum!!

Note 3:
Hmm... This only works with Peach for some odd reason...

Note 4A:
Anything that is vulnerable to ground pound will be killed upon contact!!! Activate an infinite hit stun code to kill even more things!!!!

Note 4B:
Now with hitstun!!!


All tested and working unless stated otherwise, for version 1.0 only. Made by tiger21820.

SUPER POWERFUL YOSHI!!!!!! (Peach Only)
This is the ultimate power!!!!!! You can kill almost any enemy, open "?" clouds, and activate almost any target!!!

D2000000 00000000

The catches?

You cannot push or smash things like crates, vases, blocks, switches, etc...
You also cannot collect eggs / keys / number balls (except by swallowing baddies)...
Throwing eggs or other thing will "Hit" the wall as soon as you throw them...
And morph bubbles will not work (amoung other things)!

This makes the completion of some stages impossible without additional codes...


Touching moving objects act as if they bump into a wall (Peach)
They turn around...

100016DC 0000101A

3= Flashing Egg (Unused, gives red coin when it hits something, like in the original!)
4= Sumo Egg
5= Big Egg (Looks like a Sumo Egg, but breaks when it hit's something, like when you with Peach... May be unused)
7= Key (Can be used as ammo!)
