Apperantly some character called Fanjita, who is a proud moderator at the imaginatively named PSPUpdates website, found an exploit in the game save for GTA: Liberty City Stories (which he proudly snatched from Edison Carter's Cheat Device) that enables unsigned code (otherwise known as homebrew) to be ran on the PSP. Rather going into more detail, i'll just direct you to PSPupdates themselves for more info where you'll also find a download link.
If you can't get this to work/uploaded/downloaded/removed or if it f*cks up your Liberty City Stories save game (and even break your PSP) then please don't email us as we will most certainly not be able to help you.
Please email any questions to PSPUpdates by <a href="mailto:email@example.com">clicking here</a>. The so called team over there would be happy to help you.
Also for those of you who didn't know already, Edison Carter updated his Cheat Device yet again after our last post. The latest update makes it possible to trigger the snapshot while holding other buttons. Click the links below to download and visit Edison Carter's website for more info.
