How to Make a PSP Keyboard

The PSP portable game console is very popular among game enthusiasts, but it is difficult to enter long sentences on its onscreen keyboard. Although Sony has made no keyboard accessory available, it is possible to adapt an infrared portable keyboard to work with the PSP. Doing this requires a modified PSP and is not for the casual user, but it is the only way to have a keyboard to use with the PSP.
