2.80 Decrypter Released!

Dark_Alex has modded psardumper for 2.80 which was originally created/coded by psppet. This psardumper will dump reboot.bin and other necessary 2.80 files for devhook emulation!

This is quite some exciting news as it has been quite some time since 2.80 has been released and many have been anxiously awaiting this day. The only thing that remains for us to wait on is an update to devhook that will allow us to emulate 2.80! So, now that we have the files extracted/dumped, it is only a matter of time before we are emulating this precious firmware on our 1.50 firmware with devhook!

To install, extract the data.psar (we suggest using PBP Unpacker) and place it in the root of your memory stick (data.psar). After this is done, make sure you have the decrypter/dumper file in the correct folder (PSP/Game) and execute it on your PSP. The program will then dump/decrypt the necessary files onto your memory stick. This program is legal, however the files dumped using it are protected under copyright laws - so do not distribute them!

NOTE: This will work with version 2.81, which was released today.

Firmware v2.81 Out Now

Today Sony released system update version 2.81 for the PSP. This comes shortly after FrSIRT rated the recently discovered libTiff exploit as a "high risk." According to the US Playstation site, v2.81 includes the following changes:

• PSP® systems with system software version 2.80 or earlier do not correctly recognize high-capacity Memory Stick PRO Duo™ with more than 4 GB of free (recordable) memory space.
• A patch has been added to address a security vulnerability in the system software.

Unless you're hell bent on getting a Memory Stick bigger than 4GB and willing to kiss homebrew goodbye, don't upgrade. If for some reason you wish to update then you can download the EBOOT from Sony's website.
