    psp PSP Firmware v2.8 Decrypted!

    Dark Alex has released a Decryptor for the latest PSP firmware, heres what he posted:

    How was it done? :

    The keys have been extracted from the ram that could be dumped in 2.80 using the tiff exploit.

    How to use:

    You need : 1.00 or 1.50 firmware.
    extract the data.psar from the 2.80 update eboot and put at the root of your memory stick.
    Run the 2.80 psardumper mod and that's it !

    I added support to psar dumper to decrypt 2.80.
    Decryption could be done thanks to rest of kernel stuff in the 2.80 user ram.

    I'm pretty sure that something about RSS video was implemented. You can download it but I'm not sure if it can be played. Also just the fact that it was decrypted gives us even more confidence going into the 3.XX days. I cannot wait for a 3.XX firmware to be decrypted.

    If you, say, have a 2.60 TA-082 PSP and use the firmware dump method described here, could you use 2.80 (emulated) without updating your PSP?

    No, there are a few other additions to the 2.80 firmware. My favorite feature of 2.80 firmware is being able to play Videos stored in the VIDEO folder. No more MP_ROOT folder with wierd filenames like MAQ12345.mp4.

    I would very much welcome 2.80 firmware emulation and I hope Booster re-emerges after SONY's cease and desist to give us a 2.80 enabled DevHook.

    Also, this may be the only way for us 1.50 firmware users to play upcoming 2.80 required games.

    as much as a great guy booster is, with the source code to dh released, hes kinda out of the picture. any coder with a brain, not me, could make the tiny alterations to allow devhook to run 2.8
