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.
