DevHook

Devhook is a homebrew application for the PlayStation Portable created by BOOSTER which enables users to emulate different firmwares on the PSP. The application features the ability to mount ISO and compressed CSO images stored on a PSP memory stick. This allows games to be stored to and played from memory sticks, allowing users to travel with many games for their PSP without having to carry around several bulky UMDs.

Due to it no longer being updated and the advent of custom firmware, Devhook is virtually obsolete since it only emulates up to firmware 3.11.

Features

Some other features of Devhook include the ability to run the PSP at a higher clock speed than the commercially capped 222Mhz, the ability to run games from computer via USB cable, and ability to run homebrew applications on the TA-082 motherboard. Current development seems to have been taken over by Booster who recently released Devhook 0.52.0100 beta allowing emulation of firmware 3.11. Due to minor bugs in the new version, many users are using earlier versions still while eagerly awaiting an update. Also, the beta versions still do not include the highly anticipated USBHost, which allow users to play via a USB cable.

2.71 Kernel Version

Because Devhook originally only works on the 1.5 kernel, Dark_AleX has modified Devhook to be able to run on the 2.71 kernel. This allows users of the TA-082 and 2.71 firmware users to run Devhook through HEN and be able to emulate any firmware to mount ISOs. Something Devhook hasn't completely done so far is to be able to mount ISOs without a UMD in the drive. This is still on the To-Do list of the new Devhook, as some ISOs will only function with a UMD in the drive.
