Big Hong Key?

[LightoftheDark]

I've never seen what it looks like in actual gameplay.

i dont know but my sister got that hong key and it destroyed the game and i got so mad because it so annoying but i realy got mad was because of my sister she destroyed it and she didnt even tell me

How could it destroy the game? It can corrupt the memory card, but I don't see how it could do anything to the disc.

And I've never seen a gameshark before, much less used one.
