Things You'll Need
Instructions
Load the memory stick into the PSP. If it is a new memory stick, it will need to be formatted, which the PSP will do. Just follow the onscreen prompts and the PSP will do the rest.
Connect the PSP to your computer and put it into USB Mode by selecting USB Settings from the Settings menu on the XMB dashboard.
Locate the memory stick icon in My Computer and open it. Find and open the game folder where you'll find the update folder.
Download the update software and save it to the UPDATE folder using the filename EBOOT.PBP. You can find the download link on the PlayStation Support website listed in References.
Disconnect the PSP from your computer and access the memory stick icon under the Game menu on the XMB dashboard. Find and select the update file to begin installation.
