This guide requires you to have a unpatched version of Grand Theft Auto Liberty City Stories.
The unpatched version of the game contains the 2.0 update, so if higher you need to find another

Read
Note to TA-82 or higher PSP's
If you have an unpatched TA-082 or higher motherboard, you will be prompted to allow the downgrader to patch your motherboard so it can be safely downgraded. The downgrader will not let you proceed without patching, if your motherboard requires it.
