Tetris 2.5 is now officially released! This is the first homebrew game
EVER for 2.5 firmware PSPs.
Big props to
Fanjita (might want to click on one or two of his ads on his site to help out

) on this outstanding demonstration of external code launching in the form of a game, and thanks to all the other developers who made this possible.
This 2.5 Tetris works not only on 2.5, but also has full support of 2.01 firmware too, so it supercedes the
2.01 Tetris that we at PSP 3D made roughly a month ago.
Screenshots:
Unfortunately, no 2.6 support just yet, but hopefully in the near future that will be complete too.
Notice: As a compliment to the instructions in the readme, do not autoload the gamesave. You must load an existing regular gamesave and then load the Tetris gamesave.
Enjoy!
