Urgent Pokemon Help?!!!!!!!!!!!!!!!!!!!!!!!!!… - gameshark software on gpsphone

I was looking for gameshark codes and got this message.
Important note for using GBA cheat codes ...
If you activate too many tricks, the game software, do not know how to treat so many changes. Your GBA will let you know when you are offering too much and gives the error message that says activated "too many codes. Some are not executed. Click on Start .. If you press START, the GameShark software will appear to hang . If you receive this message, it is better simply from the GBA instead of the Start button. When you turn the GBA back, turn fewer cheat codes to avoid this.
Does this mean that everyone at some point in a game? Please tell me what that means.
