It looks like there's a nifty new application you guys can use to get those Pandora unbrickers safely onto your PSPs. Mrdude has released a GUI for the Pandora's Battery system, called Pandora's Box.exe.

According to the readme, Pandora's Box contains the files needed to create Pandora's Battery, as well as the following files: "the 1.50 update file, Kxploitpatcher - so you can run 352 m33 update from 1.50 firmware, and 3.52 M33 update 4."

Note, however, that you'll still need a homebrew-capable PSP to turn your regular battery into a Pandora's Battery. That being said, it does forego the need for trying out those tutorials, though you'll at least have a choice now as to how to make your own Pandora's Battery. In any case, just make sure you check the readme for instructions on using Pandora's Box. Enjoy!
