We reported about Sony PSP Homebrew coder Fanjita releasing a Tetris game that can be loaded onto Sony PSP with Firmware 2.5 two days ago. Now he made it work on the latest Sony PSP Firmware 2.6.

To load this homebrew game you still need the GTA game to utilize the flaw in the saved game loader. I still think Sony should release a SDK and a loader for homebrew games. This could be another huge reason for people to get a Sony PSP. There are lots of gamers who love those little games or want to run productivity software on the Sony PSP. Sony could keep the UMD discs closed, but open up running homebrew code from the memory stick.
