The “Noobz” team has released the first homebrew game for 2.80 PSP’s (as well as 2.70 and 2.71). This game will also work on all firmwares from 2.0-2.80 firmwares, although 2.80 gets the most benefit out of this game as it is the "trickest" firmware that we have exploited. This single piece of homebrew is the simple game of Tetris and is made possible by the recent libtiff vulnerability that has been exploited. With previous exploits, Tetris games have been used to demonstrate the exploit, and this one is no exception.

“Noobz” has developed this game for users to enjoy, and it also demonstrates that the exploit is definetly "usable". The 2.80 is very capable of running homebrew (user-mode), but all it needs is a kick in the right direction. This homebrew game is exactly the kick we need. As for the other firmwares, 2.71 can already be downgraded with Dark_Alex's downgrader, so this is a huge milestone for 2.80 (can't be downgraded).

Even though there is no eLoader on 2.80 at this time, the team has taken the liberty to release instructions on how to make homebrew “2.80 compatible”. For those curious youngsters who want to know how this was made possible, just download the SDK package that does exactly that – shows you how it was made (coding experience is a good thing to have if you wish to understand it). Instructions on how to create compatible homebrew are also found in the SDK download
