Coders Percival and Robert A. have just released their second homebrew game which runs on 2.70 and 2.80 PSP firmware, TIFF Pong v0.1. It's a simple game of Pong that makes use of the TIFF exploit along with the 2.70-2.80 SDK that was just recently released by Noobz.

Since this is a TIFF game, the creators have instructed that to install this game, one will have to place the "Pong" folder into the "Photo" folder of your memory card. Entering the "Pong" folder will cause the game to start automatically.

At the moment, they have also pointed out that the game cannot be properly exited yet and that the Screenshot capability has not yet been put into place. They have noted that these will be fixed soon.
