ps3,controllers,emulation – Understanding DS3 Trigger Buttons’ Negative/Positive Throttles

The main functions that PS3 Jailbreak provides are:

1. Ability to run your own code on a PS3 - you normally can't do this.
2. Ability to copy games to your hard disk, and run copied disks

PSGroove apparently has limitations that restrict its use to run pirate games. see: http://www.thesixthaxis.com/2010/09/01/psjailbreak-open-sourced/

The essence you absorb to quick charge the Ultimate Technique is used to charge the technique and provides no other benefit. However, this is counteracted by the fact that enemies killed with the UT drop more essence - either 300% of normal for charge level one, or 700% of normal for charge level two.
