Intentionally lose the first mission after the Raven test, then die with -50,000 credits or less to activate the "Plus" cheats. The game will restart from the first level with all items gained in the previous game. Your pilot name will vanish from the "Pilot name" slot. The more times this is done, the more cheats you will unlock. Some examples are better radar (grid system that detects incoming missiles), fire projectiles from laser swords (press Circle, then quickly press X), cooling twice as fast, being able to fire rear weapons while in motion, and double available energy.
Successfully complete mission mode and allow the credits to complete to be able to have cores that are overweight.
