Maybe this is good news for homebrew fans that hackers have released a firmware downgrade which can change a 2.6 or 2.5 version of the PSP into homebrew-friendly version 1.5. The PSP homebrew scene becomes strong with more and better software coming at a steady rate. This new release may attract many risk takers who like to play Sony PSP games. While you should pay much attention to the instructions of this version or your Sony PSP may turn into useless. Use this with caution.
