Homebrew users will rejoice at the release of the newest version of M33. The newest release promises to have most functionality of Sony's latest firmware release, but also gives users the ability to launch homebrew applications and mods. A big new feature in this release is the ability to use a Network Update-styled interface to automatically upgrade to later versions of this CFW. To download the update, and get instructions on how to use the program, visit Dark_Alex's website
You will need to download firmware 3.80 from Sony's official website
in order to use this installer. Please note that use of any hacks to your system will void its warranty. Do not attempt installing custom firmware without carefully reading all instructions. This update will not
work on PSPs with official firmware.
