Hack the following location by entering the corresponding codes:
LOCATION - CODE Delta-Theta-Gamma Party Door - "MOZART" with Mei. To find the door, have Mei search with the decryption device. Door that leads to Jun - "FREUD". Computer - "EINSTEIN". This will give you the ingredients for dynamite. Delta Beta frat house - "PICASSO". Safe - "1873".
When you need to lockpick a door, get to the final rod. When you do, make sure the pin is stuck. Before the pin gets unstuck, shake the Wiimote up and down rapidly. The pin should go directly through the rod and into the hole at the end. Note: This does not always work.
