GNX Project (Spanish) is a complete shell for your PSP. It simulates the XMB menu with a familar design and is able to return to the shell after running a homebrew, the UMD or Internet browser without having to exit to the XMB.

It provides most of the tools to help managing data and run applications on your PSP. It also has some unique functions such as GNX Store, which allow you to download savedata for games through internet (there are about 100 available saves collected according to the developer).

This was one of the contest entries for the Scenery Beta 2009 (PSP Applications, 3rd place).
