Set XXXX to anything between 3F40 and 3FF0.

When using Power Beam, press C-stick Up to activate, and C-stick Down to deactivate.

When in Morphball Mode, Press Y on the controller in Port 1 to activate. When in FPS view, press A on the controller in Port 2 to activate.

This preserves your codes, so it can be useful if you are testing button codes. If you quit normally, it refreshes the memory and your codes go away.

The artifacts show up in your log book and their respective locations are filled in in your log book, but the impact site takes no care that your log book says you have them.

Don't save your game after using this code! It somehow corrupts the save, so everything gets reset. It is mainly useful if you want to read about everything in the game, but don't want to take the time to scan everything.

I think when you truly scan all the items, it does a couple of steps and then sets this value. By setting this value without the other steps, it seems to mess up the game.
