Today hundreds of PSP's will say hello to the world as they run their first piece of homebrew - the "Hello World" application. This will be made possible by a new exploit found that does not require one to own a copy of Grand Theft Auto: Liberty City Stories, but rather load a simple image off of your memory stick. This remarkable demonstration can be executed on 2.0, 2.01, 2.50, 2.60, 2.70, 2.71, and 2.80 firmwares!



If you are stumbling while reading this sentence, I wouldn’t be surprised. I just told you that you are now able to execute a homebrew application on 2.0-2.80 firmware. Now that you know it is possible, you are probably wondering how. With the combined effort of several dedicated users – NOPx86 (provided the original x86 proof of concept), psp250, skylark, joek2100, jimp, cswindle and Fanjita, they have managed to execute the first piece of homebrew on all firmwares above (and including) 2.0!



Less than a week ago, Fanjita dropped by our forums to tell us that a newly discovered exploit is indeed genuine and a usable exploit. This “exploit” started off as a discovery by NOPx86 in libtiff. He managed to find vulnerability and as a result – alter it to crash the PSP and many other image viewers. Fanjita, NOPx86 and the rest of this exploit team have put their hearts and souls into this exploit, and as a result they were able to execute a Hello World application on all PSP’s with the ability to view tiff files (2.0+). This application runs in "User Mode", but kernel mode will be achievable on all firmwares except 2.80.

A little video of the exploit in action this is my 2.71 psp saying HELLO WORLD and also piece of mind for people who think it might brick their psp - IT WON'T

Opens in windows media player, or right click and save target as. File is 11mb

Quality of the video isn't great, but it prooves the point, thus serving it's purpose.

Don't think I can post the links to the exploit, just PM me if you are interested and someone correct me if I can post them please.


NOTE - THIS DOES NOT DOWNGRADE YOU PSP, IT IS A PROOF OF CONCEPT OF HOMEBREW RUNNING ON 2.00+ PSP'S WITHOUT GTA-LCS
