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.

- 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.
T- his 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

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

Hahaha... I have the unpatched GTA: LCS ori UMD with me..downloading it to test...

HAHAHAHA! now i can get the MGS PO version psp!

Bleh bukak bisnes downgrading balik, bro..

Me want blue PSP.... 

Yeah, I've flashed to OE-C. It loads faster than before.

But then, I've to re-flash my custom XMB again..

EDIT: I need no flashing, now OE-C can access flash0 via USB. Just copy and paste instead.

so like theres suppose to have a folder in psp tha contains all the coldboot/gameboot/ltn0.pgf etc? copy and paste? so confrim no need to use customizer/XFlash/PSPFiler?

Actually, you are accessing your flash0 directory from your PC. When you activated 'Toggle USB for flash0', you can browse through the flash0 using Windows explorer like what we usually do, when accessing MemorStick contents. So, just cut & paste any mods that you want, like custom XMB icon, you can just paste your custom  'topmenu_plugin.rco to flash0:/vsh/resource directly.
