Pokemon Platinum Freezing.

Alright, I want to add a new team to battle my friend later on and indeed I have a good team to make. I went through the Pokesav and I made my team easily, went into the M3 Sakura firmware and had ended up putting the things together and started my game. It loads fine until I get in, about 5 seconds after it gets in the game freezes.I know it is the codes I put in, but does someone have a trick on how I can fix that?

Do you have the latest kernel?
If yes, back up all your files and try to format.
