Hey everyone! I recently bought spongebob atlantis for my 4 year old. He loves finding out everything about new games.Especially if its cheats!!!
He found all the cheats for this game but when he enters them they come up 'invalid'. I noticed that all the cheats are in lower case and the letters for entering cheats are upper case. Is this the problem and if so how do I fix it.
He's driving me nuts trying to figure this out so any help would be great.
