if this lead to downgrader, i will use PSP Universal Remote to have fun at tv shops :)
Last night I was on IRC with Skylark, one of the authors (maybe the only author?) of the original 2.00 TIFF exploit, and we (he) pretty much managed to decode the layout of the system.dreg and system.ireg files, which apparently act together as one piece of data. He even wrote a quick C program to spit out the contents of the file. However, we ran into a problem. The PSP checks the data for corruption by performing a checksum on the data - in other words, it does some sort of mathematical calculation on it to identify whether or not it is valid.
For some things I'm sure the check doesn't exist - user name, connection name, etc; however, for things like the password - which must be a 4-character string of numbers 0-9 - the checksum is definitely enabled.
The problem is this: As of 3:30AM EST, we didn't have any idea what sort of checksum function it uses. If we did, we could generate our own checksum for whatever data we want to shove into the system.dreg file, thus fooling the PSP into thinking it's valid data.
I'm sure he'll keep working on it if I ask him to - he and I get along pretty well. He and I really got in-depth last night, and had a great time doing it :)
Cool
Now we had a good team of coders involved in this
If you're at all interested in seeing what we talked about last night, I've chopped up the log and put it online: here. Be warned: it's extremely heavy on the technical jargon.
I read everything
and OMFG i dont't understand anything
Well i don't know anything about coding
but it seems
This can be something
"Skylark and Freeplay Announce the 11th Network Connection Exploit."
lool
PS:Sorry my English
I'm Portuguese
Nice work free and sky.
Let us know if/when you've solved the crc puzzle ...
whats with all the squares in the dreg file? does it need to be opened with a viewer or like decryped?
I'm glad you realize that that was a joke :pZitat:

I assume you're opening it in Notepad? The squares are non-printable ASCII characters, like backspace, tab, etc. To do anything meaningful with this file, you'll need to find yourself a hex editor. Google for them; you should find plenty of free ones. There's one called XVI32 here that seems pretty good.Zitat:
Zitat von Paradox.psp
Never mind this, It's an edit, I posted it, and then saw it had allready been answered.
After reading this, I cracked up laughing when I saw "Expert" under your name. To be honest, I don't see much in this exploit RIGHT NOW, but I'm willing to bet it can be taken further.Zitat:
Zitat von Paradox.psp
em k alot of 00 ...
and the expert things there because and got 250 posts..
7 posts, what have you done that proves you an authority? These people knw what their doing...4ucking new kids.Zitat:

Thank You!Zitat:

TO, you should put this on the first page, because this explains EVERYTHING!!!! I mean literally, EVERYTHING!
why should i put that on the first post if it doesnt directly relate to this project..i guess i will..but..
You could just say this:Zitat:
Zitat von TeamOverload
For those that are unfamiliar with buffer overflows, you can get information here(url here).
You know what i mean?
Ya, i added it :)
No idea of what use I can be, but I have a 1.50(NA) PSP(JP) with GTA(EU) (- lol, god I've got a mixture). Anything I can do to help?
There's a lot of work behind all of this, why it's still in Speculation Forum instead of PSP Hacks Forum??^^Anyway, keep up the good work
Watch out dude, how many posts you have doesn't matter upon how skilled you are, or how kool you are. This dude could come out with a downgrader one day.Zitat:
Zitat von AzureBlack
I think because it is still being worked on, but i honestly dont knoZitat:
Zitat von Timale-Kun
I had originally gotten it moved to eLoader forum, but it was moved back here. I could try my cunning to get it back there, if you'd like.Zitat:
Zitat von TeamOverload
I wasn't aware you had influence over the boards...lol...
I wouldn't call it influence as much as it is being extremely respectful and polite when asking for something =).Zitat:
Zitat von ZFB8
frozen wanted it moved back here so unfortunately i think this is where it is going to have to stay
yea look at ditlew...Zitat:
Zitat von PopcOrn DeVil
Well thats until we get an exploit...and i know we will sometimeZitat:

this may be total crap, but in the system files of flash 0, where u get all the info its got system version, then the number.....
thats nowhere to be found when viewing the system.ireg.......

Dude be proud that they have found something it might or might not influence but at least they tried
lol, what i ment is; when i had a look, there was nothing about system version in it.
i can see how that might have sounded different, but i was giving some info, not flaming. i thought that if system info was in there, then we might be able tyo do something with it.
sorry. :Cry:
No offense taken..dont worry about it :)
Wow, way to NOT READ THE TOPIC. For starters, your post count does NOT prove your authority at all. I am not a "4ucking new kid", that is stupid assumption.Zitat:
Zitat von AzureBlack
Secondly, I was referring to THIS QUOTE, a thing that WOULD make you laugh if you saw Expert under their name, even if it is a count of posts:
"whats with all the squares in the dreg file? does it need to be opened with a viewer or like decryped?"
I'm sick of these kinda people throwing insults left and right. For gods sake, just get along.
Although i agree with you, can we please stay on topic..or else i will ask to have this locked and ill only talk to devs
any progress ?
Damn is it that hard?! He will post when any progress is made!Zitat:

I think you dont want him to lock this thread?! Look at my sig....
