6.61 Adrenaline

A software that transforms your PS Vita into a two-in-one device

What is Adrenaline?

Adrenaline is a software that modifies the official PSP Emulator using taiHEN CFW framework to make it run a PSP 6.61 custom firmware. Thanks to the power of taiHEN, Adrenaline can inject custom code into the IPL which allows unsigned code to run at boottime.

How to update

If you have already been using Adrenaline, simply open Adrenaline.vpk as zip file and copy all modules from sce_module to ux0:app/PSPEMUCFW/sce_module.

How to install

Please only do this approach for a fresh installation, otherwise please refer to the guide above.

  1. Remove the Adrenaline bubble and the ux0:app/PSPEMUCFW/sce_module/adrenaline_kernel.skprx path from the taiHEN config.txt and finally reboot your device.
  2. Download Adrenaline.vpk and install it using VitaShell.
  3. Launch Adrenaline and press ❌ to download the 6.61 firmware. After finishing it will automatically terminate.
  4. Relaunch Adrenaline, this time it will go into pspemu mode. Follow the instructions on screen.

Getting rid of double launch bug

Adrenaline has been redesigned in 6.61 Adrenaline-6, so you'd need to launch Adrenaline twice everytime you reboot your device. To get rid of that, simply write this line to *KERNEL
