PSP Coder Dark_AleX has just released his DevHook Launcher port for 2.71 firmware. In his previous release, which was a 2.71 XMB homebrew launcher, the project was limited to user mode and homebrew had to be a single PBP/PRX which was not in ELF format. He was also originally aiming to have the kernel mode available via the TIFF exploit, but in this version, he has achieved just that. With this new launcher, people with 2.71 firmware can now emulate 1.50.

However, as with any other hack of this kind, caution must be exercised in order to not brick your PSP, so make sure to go over the compatibility chart and the readme file which have been included. Installing this launcher involves installing another HEN first which will be flashed, so be careful.

The creator also cautions that this version has only been tested on 1.50 and 2.71 firmware, so PSP owners with other firmware versions other than the ones indicated might want to steer clear for now. Dark_AleX has also included the following instructions:

• You need Homebrew Enabler for 2.71 revision B (minimum) to run this port.
• Get the files to emulate firmwares yourself.
• Run the pbp with the title "Devhook 0.4X launcher for 2.71". The 1.50 launcher is also included because in the emulated 1.50 you can launch it.
