I have a gameshark I put in this code: EE5CE242D694 ..

It's a Missingo or whatever you want to call it. If it looks like a question mark inside a circle that's inside another circle that's inside another circle and it's all black and white, then it's a missingo.

I used the walkthrough walls cheat, went in the Pokemon center and went in the battle place without a cable or adapter.

I went to the place where you battle, and I battled that figure and it's name was ????????. Once I caught it, I wanted to give it a different name and I saw that it looked like a gold bulbasaur. But, when I gave it a nickname and pressed done, the game froze.

I recommend that you don't do anything. Probably the best thing to do is to run away or turn off the GBA and turn it back on. Rate this answer.

P.s. If you noticed, the Missingo is the form of a Pokemon you didn't see in the pokedex.

In order to get the ice whip you have to go to Dark place of waterfalls.

On the first floor press start then press L1 to fix mode on the right of the map you will see a a symbolethat looks like an axe. Go there, you will see a walll that looks like a door.

Run at the wall and you will here a thump sound.

That mean a knight has appear with a spikey looking ball. DO NOT DESTORY IT!!!

Go in front of the wall and hold gaurd.When he swings at you, quick-step out of the way, if the ball hits the wall it should make a door.

Go in side and figure out how to get the ice wipe.

Catch it!!!!!!! It's a missingno short for missing number the rarest pokemon!!
