Im beginning cracking 2.0 . . .

Oh yes - one more quick pointer.

Screw looking at firmware all together - check out some of the first gen games for an exploit that will allow you to boot unsigned code ala Mechassault on the Xbox.

This method circumvents all firmwares and will work on all machines too - plus I think it will be easier to find a flaw in a game (esp. gen 1 titles) that it will be in 2.0

Combine this exploit with the new firmware launcher thats currently in devlopment and you may be onto something...

I wish you the best of luck in your project/mission.

If I was using 1.51, I'd send it to you, but I'm a 2.00-head.

I'm NOT going to whinge about how others have tried and failed, which apparently means that you definitely won't succeed - because you just might do it. Just gotta have faith.

One thing I will say, lots of people will LOVE you if you can find an exploit or a way of executing unsigned/uncertified script within 2.00, rather than trying to compile a downgrader for 2.00.

Just my two cents. Good luck dude.

Thank you I drum and your willingness to assist me im still trying to learn more about the eboots and im going to visit ps2dev.org and learn up on some stuff there. I'm a rookie at this for the most part but I believe that i am capable to do SOMETHING.

once again people I am looking for suggestions or things that have NOT WORKED. Also a 1.50 ( i would feel bad if you sent me this. . . ) or a 1.51 firmware would be golden. NOTE-If I BRICK your psp i will not give you a whopping 250 but i will make it up to you to some extent. But I will try most of my attempts on my 2.0 because its mine and i wouldnt feel bad for ****ing it up because i have 1 .5 too I just want to do this to benefit the community

comments are appreciated here! no flaming other users ideas please! that just takes up worthless space. Some stupid ideas are even good because i can breech off of them and possibly dig deeper into them.

[FF10Freak]

stupid ideas? You read my topic? XD if yes ... what do you think about that? You know more than me ... im working together with a friend on that ... well now. We think to know that those "data.psp" and "data.psar" are written in C++ are we right? dont know exactly. If you know sumthing tell us ... its for the community XD XD. k ... thats all to me. >_>

[alexh]

the answer is not to downgrade 2.00 but merly crack it to run homebrew you are not gonna downgrade a psp this century

Erm if you can run anything I suspect you can downgrade

I think the front line attack (i.e. a modified firmware file) isnt the right way to go... the use of modified saves for original UMD games which exploit overflows etc. may be the way in as with the X-box soft-mods, plus the added bonus of not bricking your PSP during development

Edit: NoNZero has already suggested this

I have downloaded the program pbp unpacker and am in the process of learning more about the eboot files. I have learned what is in this little file though (all the parts that are in it that make the games people create. . . )
I just dont exactly know yet about ho to make a game. . . once i learn how to ddo that i just need to make adjustments to how to create it and try the files out on the 2.0, 1.51, or 1.52 i think i can whip up some form of progress.

[Cap'n 1time]

just an idea (which is weird because i hate hearing ideas on this subject). Would sony begin to try to load extracted data from a UMD on a MS? Its already signed, so it might do... well.. somthing. Play with that idea for a while eh?

[Dj SaTuRn]

Seriously, this is software thats been locked by a Billion dollar international company. Its been looked at by some of the scenes finest and is still... so the real question is... who are you and why should we care? - no offence meant by that statment.

hell, Bliazzard is probably a billion dollar company by now, you know, warcraft series. Well im just saying that they tend to leave flaws in their programming that allow us hackers to take advantage.

So you could be right most likely, but i think that they must have left something out.

[nonzero]

but i think that they must have left something out.

A lot of devs have alluded to the fact that there is a glaring security hole in 2.0


Wishful thinking or the truth?
