    You remember that the only thing holding us back from a downgrader for v3.03 was the lack of a user-mode exploit?

    Well, we don't like to be held back from anything, so we went back to basics and looked over some of the old exploits. And what do you know? We found one!

    We did a little digging into the old GTA exploit, and discovered that it hadn't been properly patched after all. We'll leave it as an exercise for the interested reader to figure out exactly how we got past the patch (and to give Sony a little while longer before the head-slapping "Doh!" moment ).

    But the short version is that we can now run code again via Grand Theft Auto : Liberty City Stories. You want some proof? Check out the Goofy Hello World download below. Here's a little screenshot:



    Some details on how to use it:

    You need an original, unpatched GTA:LCS game. See here and here for tips on how to check your version, although it can be confusing. The new copies that you find in the shops now will not work.
    This only works for Liberty City Stories, not Vice City Stories.
    Extract the files from the ZIP into the /PSP/SAVEDATA folder on your memory stick.
    Start the GTA game, and enjoy the feeling of freshly-minted homebrew :D

    And what of the future? Well, we should have a 3.03 downgrader ready within the week, using this exploit.

    Goofy FAQ:

    Do I need GTA:LCS?
    Yes, this requires an original unpatched version of GTA:LCS. Once the downgrader is released, you will only need to borrow an unpatched copy of GTA:LCS briefly to perform the downgrade.

    It didn't work!
    Verify that you have an unpatched copy of GTA. Only GTA:LCS UMDs that contain a copy of the 2.00 system update will work.

    It still didn't work!
    Having other GTA savegames on your memory stick can cause problems. Make a backup of your memory stick contents, reformat the memory stick, and copy only the files from the Goofy ZIP onto it. Restart the PSP and try again.

    Do we have access to kernel mode?
    It's a bit tricky, but yes, the kernel mode hole found by Team C+D still works from the Goofy exploit. The downgrader will use this to perform its magic.

    Should I upgrade to 3.03 in anticipation?
    The downgrader will require 3.03, but you might want to wait until it comes out before upgrading, just in case!

    Will the downgrader work on all PSPs?
    That's the plan.

    Does this work on custom firmware?
    If you're already running a custom firmware, congratulations, you have no need for this. But the Hello World should still run if you'd like to see it in action.

    This is one small step back for sony, one giant leap for homebrew

    I just read that 2
    this is soooo awesome
    but it might be kinda hard for some to do cyz u need an unpatched gta
    this is great cuz now it doesnt matter what fw u have and we'll a cuple of weeks before the "whens the 3.04 down grader coming out"
    the patch from sony might take a while cuz theyll have to find it and patch it will out any more holes
    I think the homebrew community has made HUGE progress
    i got 2.8 and if this downgrader is easyer then i might do it
    i got a friend whos got an unpatched gta
    we have to start a way (with collaterial) to pass unpatched games around
    sorry for the huge pic but thats the only way it worked

    Hi, I have PSP @ 2.81. After i downgrade it, am i correct in saying that all i need DAX's custom firmware and a large memory stick to play isos? I no that you needed Devhook before the custom firmware, but i presume you can run them straight off now, is that right? Many Thanks for your help.

    upon downgrading to 1.5 fw you can go to 3.03 oe-c straight away to play your iso..no other application needed.
