YokimaSun writes: Noobz have today released a new exploit in the game Lumines — allowing unsigned code to be ran!, from the article:" 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."
