what?

He thinks it's exciting and cool that there might be homebrew for 2.70 users. :P I agree, I can't wait 'till you finish.

hey people,

Please let's try and keep this thread focused on what it's about. Let's just wait and watch until anything develops rather then back slapping and 'cool' etc..thanks (ps: Yes i'll shut up now)....

i just had to sign up for this forum to reply. omfg.
so i've read your whole story in your first post. well, you think you can adjust the function of X and O in the update eboot huh? Guess what, the error message is from the firmware itself! it doesn't load the update eboot cuz it's corrupted, so it didn't load ANY data from it. it's just a glitch in the error message, on certain type of psp's. get to the real world noob. you have no idea what you're talking about. 10000 times OMFG.

edit: i just looked at page 9..so you're making up excuses of delay, like all the fakers do. grounded? yeah right. almost done with 'the hack'? IT'S NOT A HACK. come on people. sorry to destroy your hopes, but please believe me, this guys a faker who hasn't got a clue.

edit2: jesus christ..i kept on reading on the previous pages..and i can't believe what $#@! you're telling these people. '
i'll quote you:

now i got an idea, maybe i could code a game for 1.5, that when you open it, it looks for ms0://psp/game/update/eboot.pbp and edits it from there!
this could work, and may lead to a perfect pbp file, with the signiture intact, that runs on every firmware, under 2.8 (or maybe edit the sfo to say 9.99 fw update?)

tell me your opinion, i want to hear from you
-----------------------------------------------------------

my opinion? OMFG you're so dumb it's not funny anymore. even if you could make this program, it would **** up the encryption. editing an update eboot, no matter how you do it, with psp or pc, will corrupt it cuz of the encryption. unless you have the sony encryption keys, you can't do anything with a modified update eboot.

i WAS grounded
thats it, and as of yesterday, im not anymore
and actuallly, i have opened up the eboot, and i have actually seen ALL the code within it
ive opened the pbp file with a lot of different programs
and it never kills the signiture
the reason i havent gotton it to work yet was the prog i made, since its made with lua, cannot save a file thats about 20 megs
wich means, i have to use c/c++

yeah maybe you was grounded. but your 'hack' is still fake. opening the eboot files doesn't kill the signature, but editing it does!
and what do you have to say to all the things i mentioned in my post, huh?

[crait]

well, basically all you said was im a "noob" and you complained about how im a fake
and what i have to say about that?

go back to pspupdates.qj.net
no one likes your kind here

because at dcemu.co.uk we take pride in saying this site is friendly, and full of constructive critisism, if its to say, hey man thats a good idea, or if its hey man, i dunno if it will work

I already discussed this, once you've edited the eboot the signature is broken. This is due to the fact that the filesize and the overall eboot itself has changed. You may be able to change the version number, but thats about it. Any huge change to the eboot will break the code inside.

[crait]

the reason the signiture breaks is because when the eboot file is opened, on ... lets say notepad on your computer
the file automatically checks in a predesignated area for the other part of the signiture (i dont know what its called)
i also do not know where it is, but for now, lets say its under flash0:/utils/sig
ok, on the pc you dont have a flash0:/utils/sig so the signiture breaks
when you want to update on your psp it checks for flash0:/utils/sig too
which the psp DOES have, so the signiture does not break
so it doesnt matter what you use to edit the eboot, or even open it on your psp, as long as flash0:/utils/sig is still in your flash or rom, or where ever it is
so if you were to edit the eboot, and open it with my program i made, it would look for flash0:/utils/sig again, which the psp still has, so the signiture does not break

this signiture check kinda runs like the AUTORUN file on cd's
i know Geep has the autorun file to automatically open the flash video on the cd, and since my compy is like 300 mhz, it slows my compy down a lot
