Well, it turns out that Sony has an update to add to the overall system stability and help out with preventing piracy that can be enabled with the latest pseudo-signing tricks that the PSP hacking community (most notably Mathieulh) has sent out. It’s said that our signed homebrew will work on all of Sony’s official firmwares, though, right? Well, does it work?
The answer is yes, our homebrew does work! This is great news! But, what does this new firmware add? Well, it adds preventative measures to using an HEN to enable homebrew launching from the XMB and a few other naughty PSP homebrew. So, should you update to it? For the first time ever, I think we can safely say that if you want to, go ahead. There’s plenty of homebrew that works and it will take very little time for a new release of the HEN to work on these official firmwares. Sorry Sony, but you cannot stop what has started…

Total_Noob, GEN team member has apparently finalized what will allow PSP 1000, 2000, 3000, pspgos owners to use their homebrew. There is no current release date to be announced but at least before Christmas. Something to note: This flaw is in PSP firmware 6.30 and 6.31 but is less stable which is why he is concentrating on 6.20.

So, Total_Noob found a way to enable launching homebrew on the PSP via the XMB! If you guys were around the PSP scene to remember ChickHEN or even the HEN from the 2.XX era, then you’ll be familiar with the term HEN and what this kind of stuff this new exploit will allow. Currently, it works up to the 6.2 firmware and launches from HBL (homebrew loader) from the Patapon 2 or the Hot Shots demo from the PSN.
