The Illuminati Exploit
-=-=-=-=-=-=-=-=-=-=-=-
Official website: www.noobz.eu
The All-Seeing Eye is watching you...
Following research in conjunction with Archaemic, Noobz are proud to present
the first ever all-firmware exploit for the PSP. Based on Lumines, the
"Illuminati" exploit is a user-mode exploit using a buffer overflow in the
savedata file - similar to the GTA exploit.
That's right - if you've got a legal UMD copy of Lumines, then you can run
homebrew on your PSP - whatever the firmware version. That includes v3.50!
Right now, the only homebrew is the Hello World demo released below - but
in future we intend to release a HEN and downgrader.
To make the exploit work:
* Check that you have an EU or US version of Lumines (ULES00043 or
ULUS10002). Currently we don't have a version for the Japanese
version, but we're working on it, as soon as we get hold of a
Japanese UMD.
* Extract the contents of the 'MS_ROOT' folder from the ZIP file
into the top-level of your memory stick. (HINT: If you wind up
with an 'MS_ROOT' folder on the stick, you've done it wrong).
* Start the game, and as soon as it gets to the 'Press START' screen,
press START. If you wait until the demo has started, the exploit
may not work.
* The screen should go blank, and the exploit will start after a few
moments. It doesn't do anything except look pretty at this stage
- but feel free to enjoy the first homebrew on your v3.10 - v3.50
PSP!
