Fanjita, the most famous PSP hacker in the community has released a working Tetris game with his 2.0+, 2.5 and 2.6 GTA exploit code a few days ago. Yesterday he released the source for it and a DevKit for other developers to port homebrew code on top of it. Even with a lot of limitations, In just a few hours Pong and Snakman have just popped up. Meanwhile Fanjita is working on the EBOOT loader that will provide (almost) full access to the PSP and to the already huge collection of homebrew software around.
