The problem with the codes

[SONIC]

I decided to try the codes in SSBB. But when I walk up to the moment of code (I have the character selection menu), the game freezes. Help.
P.S. If something is wrong, forgive me.

Question is... what codes are you using?

If some of them conflict... it will freeze...

Are you also using the latest version of Gecko OS?

Use the code so you can begin to play alone without opponents.
Use latest version of Gecko.
