    Yeah, at the moment our data is a tad corrupted, for instance the TEXT:


    [Register or Login to view code]

    Which, should be:

    [Register or Login to view code]


    [Register or Login to view code]

    As you can see, the data is offset quite a bit, let alone every time I crash the PS3 it takes nearly one hour to get the sploit back!

    Damn, that sounds exhausting

    But that line of corrupted text sounds like a little child who tries learning to read

    im..ima...image!

    Well, it seems to me that, as it's usual for a 64bit architecture, you are just reading 8 bytes at a time. So to fix this it would be enough to change your reading loop from

    for(i=0;i<N;i++)
    dump(lv1_peek(i+base));

    to

    for(i=0;i<N;i+=8)
    dump(lv1_peek(i+base));

    Question

    CJPC, how much are you in a mood to try kicking-in a quicker signal to do the sploit ?

    Maybe going down near as possible as we can to 1,25ns (that's the initial timing of the XDR set) it could be possible to avoid data corruption...

    Heh thanks - that would be the exact issue and fix - nice work!

    Of course, in the mean-while we sorted another (more automated) way to get it dumped - stay tuned!

    Like a modded keyboard with a delay cell to synchronyze the input of the signal right after the input of the "disallocate" command ?

    i'm more of a reader than a poster.. but i had been wondering if this was a one time deal or if it had to be redone every time it reboots.. I assumed by the way it works it had to be redone every time... which i'm sure sucks! Good luck though! I can't wait to see the dumps.. doubt i will find anything with my current limited knowledge but i do know how to work ida and i'm sure i'll waste a few nites staring at stuff i don't understand for the heck of it =P

    This is great, hopefully someone will find something to enable some sweetass homebrew

    I was also wondering after you have all snooped around a little and hopefully learnt some new things, would it make it any easier to craft say for example malformed tiff images or saved games etc?
