I put the code in for Deoxy and Groudon on my sapphire....but when ever i come to the tile they are the game freezes........ and since i put in a code for a new Treecko, every other pokemon is available... Can someone help me?

It's because Codes arent good for your game, their known to cause freezing.

Nintendo from what i know i guess puts in a detection system and sometimes when you put in codes there is a chance that it will find out and freeze your game...i have no clue though hehe

Yeah, just don't use codes, you can catch
all pokemon without using codes and it is a lot saver..
