javipas writes "The PlayStation Portable made by Sony is a wonderful device for all its user base, but it's even more great for those that have been able to run homebrew applications. The firmware upgrading roadmap had made impossible to downgrade certain consoles to a 'homebrewable' firmware, but a new exploit called Illuminati has been discovered to allow this task. Using a Lumines original game UMD anyone can now access the kernel mode that allows to run any kind of homebrew application. For the moment only a little "Hello World!" demo has been released, but soon a universal downgrader will allow any PSP user to access any kind of homebrew application/task. Running games from the memory card included, of course."
