    Default How to decrypt & patch 6.20 games using isotool

    Introduction

    Guide Last updated : 16 June 2010 (see changelog below)

    It looks like patching PSP games is the way forward. Here's a guide that shows you how to decrypt and patch games which require OFW 6.20 using isotool.

    This tutorial was using version 1.43 of isotool but since then there has been a new version but the decrypting method is still the same. For this procedure to work you must be using an UNTOUCHED ISO.

    This guide will be updated as when new games are released and also new methods/tools are released. I will later on add a section that shows you the extra steps to take for 5.00 based CFWs.

    some games need to be patched using prometheus to run right

    Harvest Moon: Hero of Leaf Valley (USA), need to be UNTOUCHED and be patch by prometheus to run right as a FULL USA iso, on CFW

    if you don't use prometheus
    the game runs, BUT, buggy(crashs, and things don't unlock) and has NO SFX
