How to Download Devhook on PSP With Firmware 5.03

Devhook is an emulator application for the PSP that allows a PSP running firmware 1.5 to emulate a newer version firmware, like 5.03. The PSP with the Devhook application handles firmware updates as if it were updating from any newer version of the firmware required for the update. Downloading Devhook to your PSP with firmware 5.03 requires the loading of Devhook and then installing the 5.03 update.
