Pirata Nervo's on a full swing as he releases his "full-fledged shell replacement for the PSP", NervOS, upping the version to 2.1. This homebrew needs no introduction at this point, but just in case you're new to the scene (newcomers are always welcome!), it allows you to play music, view images, play games, run homebrew or prx plugins on your handy dandy handheld.

What's new in version 2.1?

* NervOS Installer: Added Network Updater
* Changed the original theme (credit goes to CO_ol)
* Added new original theme (Original Black)
* Unpacker (only unzips for now)
* Control Panel: Added option which launches Unpacker
* File Browser: if you select a .zip file, it opens the unpacker


Everything else you need to know is in the .pdf file included in the archive. It's really comprehensive, with installation/uninstallation instructions, controls, tech assistance, change log and more in it, so be sure to read it.
