The news broke early this morning that all versions of PSP Firmware from 2.0 right up to the latest 3.03 are vulnerable to a user-mode exploit that allows code to be run.
The hacker group Noobz posted a Hello World proof of concept, exploiting, once again, the GTA:LCS savedata 'sploit that caused previous firmware security to crumble to the 'homebrew' scene. By going back and re-examining some previous hacks they discovered that the FW patch issued by Sony didn't completely fix the hole. Nice coding Sony!
Given the uber-homebrew-dev Fanjita said only this week that the current kernel mode exploit that allowed the 2.80 downdater to work seems to be unpatched right up to 3.03 which means that all the scene needs is a user-mode hole in order to leverage it. And bingo! Here it is, courtesy of our friends at Rockstar! Not only do they make great games, but they enable the entire homebrew scene!
Anyway, my best bet is that anyone daft enough to have updated beyond 2.71 should be able to play homebrew by Sunday night.

All PSP Firmware Exploited - R* To Blame Again!

Talking of firmwares I'm currently running Dark_AleX's Custom Firmware 3.03 OE-C.
I was surprised to find that these guys are actually hacking their own custom firmwares which you can flash onto your PSP (if it's homebrew enabled, ie. at the moment, up to 2.71)
As the name suggests this is a hacked version of the latest 3.03 firmware from Sony, but homebrew-enabled (don't ask me how) with some extra bells and whistles such as: Plays ISOs without Devhook, plays PSX games, supports extra video codecs.
The installation was a little bit of a rigmarole, but nothing too scary really. First, I think you will need to downdate to 1.5 and then run the two programs to first create your hacked firmware, and then to flash your firmware.
Anyone who wants their hands held, I'll be happy to help out at the next Fi...
This 3.03 OE-C firmware actually allows access to the flashed firmware areas by usb connection!!. While this is obviously fairly dangerous, it's also incredibly exciting. As this allows quite extreme modification of system parameters there is a burgeoning, if ugly and amateurish mod scene based just on customising the PSP icons and fonts.
I tried to make some iPhone-like icons but they're required to be 64px-square bitmaps in only 8 bit colour, so what I had to work with came out looking pretty nasty. So instead I'm planning to make some nice simple glass-like monochrome icons based on that style.
I should add that it's not trivial to enable this possible PSP-bricking USB mode. It's not something you'd do accidentally with a few idle key presses.
I love it when a plan comes together.
3.03 Homebrew enabler (HEN) and downgrader.
Crrrrrrrrrrrrrraaaaaaaaaaaazzzzzzzzzzzzy Jal gets in there early with the help from tech support (thanks H i r 0!) via msn!
Stupidly i updated my psp as soon as the vcs came out - rendering me non iso friendly (doh), and the following week watched as everyone succesfully cracked thiers and started playing downloaded iso's. How mad was i that i had to play my "payed for discs" how old school did i feel!
Anyways that has all changed. I went out on a limb and about an hour later was playing syphon filter via my recently up-down-back up graded software.
It looks pretty good so far. You dont have to boot into a different mode to access your isos, you just access them all from your original menu screens under game in the card section. They preview just as the save game icons preview.
I did have one heart stopping moment where after cracking the thing and uploading SF to my card, the machine went blackscreen and froze up. This i found was because the iso file name was too long and had a weblink in the middle of it - so keep your filenames short.
I dont think i can take fancy screen shots mid game like you guys, but what the hell, i can live without that.
so... thats another 7 games up on ebay towards my wiiiiiiiiiiii!!!!!!!!!! cool bananas.
did i say thanks H i r 0?
The screencap is not rolled into this firmware, but there are firmware plugins that you can use somehow. I'm looking into this now.
