I'm having trouble accessing the "link battle" option in the Pokémon Center after I did some massive sharking. I had restarted the game because gameshark crashed my original game. After the game crashed, I continued sharking up my team. However, after I sharked it up, I went to play my friend and the "link battle" option wasn't open, since it was a new game.
I began to gameshark myself through the game quickly, hoping to stumble onto the part of the game that "unlocks" the link battle option. Unfortunately, this only further disoriented my game because now I can't access the link battle option, at all (I must have passed by a critical portion of the game, screwing up the code)!
When can I use the link battle option?
(I've been past Ecruteak City, so I'm almost positive it's a gameshark-related problem)
How can I turn on the link battle option?
Is there a gameshark code to do this?
Please, can somebody give me a hand? I've practically gone insane trying to figure out what I've done.
