Hello World 2.0-2.8 GTAless Brew

"Finally, it's here! As of today, the world of homebrew is no longer restricted to owners of Grand Theft Auto.

Following the publication of a new proof of concept TIFF vulnerability by NOPx86, a team of PSP developers has been working hard to turn it into an opening for homebrew on the PSP. We're pleased to announce that the wait is over, with the release of a Hello World demo that runs on all PSP firmwares that are capable of viewing TIFF images!

You can see a photo of it in action here. Alternatively, you can click here to download it and see for yourself!

To install, just unpack the ZIP file to your PSP's PHOTO folder, and then attempt to view hello_world.tif. Hello World will launch automatically. You may find that occasionally the full screen doesn't show - this is a known problem, just restart your PSP by holding the power button until it turns off, then open the image again. To quit, hold the power button until the PSP turns off.

So what happens next? This shows that we can run code via this exploit. It won't be too hard to develop an eLoader that can use this exploit on v2.0 - v2.6. v2.7+ will be harder, due to extra security, but will happen a little later. Kernel mode is unavailable on v2.8, but it is likely that a downgrader is possible on all other firmwares. But then, with the possibility of kernel homebrew running without the need for a game UMD, why would you need to downgrade?

Full credit is given in the Hello World, but repeated here: Thanks to NOPx86 for the initial proof of concept on the x86 processor, and psp250, Skylark, Joek2100, CSwindle, JimP and Fanjita for the PSP work. Thanks also to Ditlew, HarleyG and our families for general support during this work. "

you might be able to run brew but without a kernal mode theres no downgrader for a while

i might as well try it out, if it bricks i will just go buy the mod chip to fix it up (probably will buy it anyways because no downgrader)

just a question, 2.8 will still be able to run homebrew though right?

i will get back to you in a bit about the program

I threw up a news article on it, although I'm not accustomed to writing in the format given, it's still up. Kinda funny how I saw this on QJ and said "OMG!! Must WRITE article........ AND MUST FORESAKE HOMEWORK!!" It would be funnier if it wasn't true. But anyway this sounds like it could open up some doors and 1 more accomplishment to shove in SONY's face.
If you're thinking about discussing possibilities might I suggest a topic dedicated solely to that? Or you and edit it into your title, either way it's still being discussed.
