Code Retard

According to psp-4000-chatter”>Eurogamer, the PSP-4000, Sony’s next generation PSP handheld gaming console, will be unlike any of the previous three generations. The PSP-4000 will include a sliding screen that will cover the buttons when closed and will do away with the (pretty useful) UMD drive. The screen will have the same specs as the one on the PSP-3000 except that it will slide. The decision to make the PSP slide like a T-Mobile Sidekick is for space savings, since the unit will be “significantly smaller in width” when closed. This won’t stop gamers from playing certain games though, as the shoulder buttons will still be accessible. Games like Loco Roco will continue to work while the PSP-4000 is in this state. That is, if all this ballyhoo is to be believed anyways…

Guerrilla striked a deal with gamespot that gave them exclusive Killzone 2 demos to give out to those who preordered the game.  The rest of the people who did not preorder the game will have to wait until release date (2/26).  The only way for those in the America to play the demo early is to make a PSN account that belongs to a  different region.  Simply go to the UK PSN page and make an UK account.  Log into your UK account on the PS3, and the Killzone 2 demo should be on the download list.  Enjoy!

The latest iPhone 2.2.1 firmware was recently unleashed to the world by Apple and just mere days later, the iPhone Dev Team provides the PwnageTool unlocking software. We’ve covered the PwnageTool upgrade steps before, but since QuickPwn 2.2.5 does the same job a lot easier, this guide will show you how to upgrade, jailbreak, and perhaps unlock your beloved Apple iPhone to run on the latest and greatest 2.2.1 firmware.

The newest iPhone 3G 2.2.1 firmware update from Apple was released earlier this week and iPhone Dev Team’s Pwnage Tool has just been released yesterday. With PwnageTool, you can create your own custom iPhone 3G firmware from Apple’s official IPSW file so that you can continue to run the yellowsn0w software unlock. The 2.2.1 firmware update contains a baseband firmware update (02.30.03) which is not compatible with yellowsn0w. This is a major problem for iPhone 3G users who wish to update to 2.2.1 firmware but still want to keep their iPhones unlocked to use outside of AT&T. This is only possible with a custom firmware created with Pwnage Tool that strips out the baseband update from the upgrade. This is great… if you have a Mac. Windows users are left in the dark for now, at least until QuickPwn for Windows gets released.

But if you don’t want to wait, we’re actually providing the custom IPSW firmware as a free direct download created with Pwnage Tool for you to update your firmware without needing to wait for QuickPwn for Windows to come out. This only works, however, if you’ve previously pwned your iPhone before. With this firmware update, you simply need to put your iPhone in DFU recovery mode, launch iTunes and shift-click (Mac users option-click) on restore and browse to this custom firmware and use it to update your iPhone’s firmware. And that’s it. Since you’ve previously pwned your iPhone before, QuickPwn isn’t necessary for you and you won’t need to wait for QuickPwn Windows to be release. If it hasn’t been pwned before, then you’re out of luck and you’ll need to wait.

TVersity is a powerful free media server software that supports a huge variety of video streaming platforms like the Sony PS3. However, with some MPEG-4 videos, the PS3 outputs a "The data type is not supported" error and refuses the play the video file. The reason for this is because for PS3, TVersity is configured to let its target platform to natively try to play the MPEG4 video file. But not all MPEG4 files are the same, as the MPEG-4 Part 2 files will not play natively on the PS3 and will cause the data type not supported error to appear. As a workaround that will not affect other MPEG-4 formats that can be played natively, you can make this simple modification to your TVersity configuration so that only MPEG-4 Part 2 files will be transcoded by TVersity and not affect other video formats.

GripShift has a buffer overflow vulnerability when loading savegames. The savegame contains the profile name which can be easily used to overwrite $ra. The savegame file is pretty big (25kB) so you have lots of space to put your code there. I wrote a simple blob of code to paint the framebuffer completely white (to just indicate that arbitrary code is running). The return address is located at offset 0xA9 in the file. In this poc it points to 0×08E4CD50 (which is only a few bytes after the return address), and the code starts at 0xCC in the file.

It was tested on 4.01M33-2 with US version of GripShift (ULUS10040), and psplink.prx, usbhostfs.prx and deemerh.prx loaded (also without psplink and usbhostfs). The decrypted savegame (sorry, couldn’t [be bothered to] get Shine’s savegame tool working so it’s in plaintext form) is in the SDDATA.BIN form which Hellcat’s Savegame-Deemer produces (thanks to him, if the program didn’t exist I wouldn’t have bothered with this). Just copy the ULUS10040SAVE00 directory to /PSP/SAVEPLAIN/ and run the game. EDIT: yeah, don’t forget to have Savegame-Deemer working, duh.
