TIFF Based Exploit found, Firmware 5.03 Says Hello World!

PSP firmware 5.03 running the TIFF Exploit!
The day many PSP owners have been waiting for is coming, as PSP homebrew developer MaTiAz has released a TIFF-based exploit in the form of a “Hello World,” proof of concept for PSP Firmware 5.03. So the idea of running homebrew on TA88v3 / PSP-3000 is rapidly approaching! (This is no late April fools joke)
*Update* 14-April: Version 2 has been released. Works on the Slim & PSP-3000. -> Hello World TIFF Exploit Version 2
The exploit is run in the PSP’s photo menu and takes advantage of a vulnerability found in the TIFF image library. Just think in the old early days of the PSP scene when using software downgrades and GTA: LCS TIFF exploits etc was the way to go.
This current version is only for PSP-1000 (Fat) units at this stage. But don’t fret a separate release is being prepared by MaTiAz for Slim models. Both the the PSP-2000 and PSP-3000 (Ta88v3).
MaTiAZ also commented that “a bit of awesomeness” is due out soon. We’ll keep you updated on this. Looks like we’ll all soon have hombrew access again on Firmware 5.03.
The days of TIFF based exploits aren’t long gone, at least not yet
Here’s the third TIFF exploit for the PSP, enjoy.Just copy the files to the memory stick root, disconnect USB and go to photo menu.
Don’t dismiss the exploit even if it doesn’t work on the first time, it’s *very* unstable.
You might get it working on the first time, but you might as well have to try it 20 times!The h.bin is loaded to 0×08800000, and the text address of paf.prx is passed in $a0 to the
binary code. You can then trick out function imports, like for example sceDisplayWaitVblankStart:sceDisplayWaitVblankStart = (void*)(paf_addr+0x15F068);
This release works _only_ on fat PSPs. The slim version will come out later.
I’m not gonna include a list of credits here, I’ll just forget some important names and then
I’ll be screwedThe people who need to be credited will know it anyway.
Have fun!
P.S. Just wait a few days, there’s a bit of awesomeness coming up.
