Thanks to some great work by neur0n we present to you his 6.60 ME addon for Time Machine which was a homebrew app originally released by Dark_Alex that takes advantage of the recovery setup for the Pandora Battery and lets you boot firmwares from a memory stick.A  It lets you change default settings and customize in a number of ways.A  If you add this to 6.60 ME you can play games requiring a higher firmwary and use 6.xx plugins.

There are a few downsides which can be viewed at the source do make sure you check it out before installing.
