LibMPEG on XMB Crash! Possible Exploit!?!

[skrapps]

i also tried it on a 1.54, doesnt work. however i think this same thing used to happen to me when i tried to load my codebreaker disc.. it would hang the system up. i wonder if it has something to do with usb drivers..possibly the same reason why usb slots dont work sometimes when you play a p22 game on ps3

Just thought about something v1.00 doesn't have libmpg yet does it?
Cez try putting DVD in and then trying the file

Until there is a way to inject code it isn't 'usable' so correct, but yes several games run on the lower versions (Untold Legends PS3 for example uses 1.02, for example). Also, as mentioned earlier in this thread the easiest way to find holes for later Firmware versions is to get homebrew running on the lower ones so that a lot more can be examined. Btw Linux requires 1.10 (mine is at 1.10, and I'm running FC5). ;-)

Here is the new file, I reproduced the result with another file and worked on cleaning it up till I knew where things were going wrong. I hope this is useful

Here's the new file: (512KB)

And here's the image of the crucial points. The first is the mixing point between header and footer. The second is the very last byte before the the crash will not occur.

just give me homebrew!!! I don't care about iso loaders. I just want the doors opened for home devs to make inovative apps for ps3. emulators, media centers, cell based video encoders etc...wooooo! good job hacked!! once you get the door opened maybe you can start gutting the firmware and making a custom one like dark alex on the psp side.

I think ps3 sales is gonna skyrocket soon thanks to you. LOL!

keep up the great work!

I put in Taladega Nights, tried to start the file (its in a memstick duo): The data is corrupted

I played Taladega Nights, back to XMB run the file: The data is corrupted

@hacked2123 - what made you decide to make some changes to a mpeg? I mean could it just be possible that with the changes made with a hexeditor that it crashes cause its not in proper format?
