“Devastation strikes! The “N00bz!” have yet again left the entire PSP community in a state of awe. Without a doubt, in the coming days, everyone will have the opportunity to downgrade, enjoy glorious custom firmwares, homebrew, and much more… This newly discovered exploit works in a similar fashion to the GTA save game hole; however, this time ’round you’ll require a legal UMD copy of Lumines. Read on…

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.

* 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 ”

so get urself a Lumines UMD from geant soon , before it gets
patched.
