Adrenaline

Adrenline is an application that can be used on homebrew enabled PS Vitas and allows for booting a full PSP custom firmware with support for plugins, PSP homebrew, and PSP game backups.

Official documentation for Adrenaline can be found here.

There is a fork of the original Adrenaline maintained by Isage (currently version 8) that includes numerous fixes, various new display settings, a new CFW called Epinephrine, and the option to run under ARK-5 CFW.

Installation

1. Download the VPK of the latest Adrenline version from the provided link. 1a. If you already had Adrenaline before version 8 you need to update the old NoPspEmuDrm plugin with the NoPspEmuDrmArkMod (Autoplugin II will do it automatically)
2. Transfer to the VPK to the PS Vita's memory card with FTP or USB with Vitashell and install it.
3. Exit VitaShell and open the LiveArea bubble for Adrenline.
4. Press to download the official 6.61 PSP firmware.
5. Adrenaline will automatically close itself when the download is finished. Launch the app again.
6. Press to install the PSP 6.61 firmware.
7. Press to boot the PSP home menu. (Also known as the XrossMediaBar, or "XMB")
8. Go through the initial first time setup.
9. The installation of Adrenline is now complete. To close it, hold the PS button to open the quick menu, then select Settings → Exit PspEmu Application

Adding the Adrenline Plugin

This is needed to fix the double launch issue.

1. Open VitaShell.
2. Navigate to tai/
   • If ux0:tai doesn't exist or does not contain a config.txt, press ○ again and then navigate to ur0:tai
3. Press on config.txt to open it in the text editor.
4. Highlight the *KERNEL line with the cursor and press to open the menu.
5. Select "Insert empty line" and highlight the new blank line. Press to edit it.
6. Enter ux0:app/PSPEMUCFW/sce_module/adrenaline_kernel.skprx on the new line you just created.
7. Press to close the line editor and text editor.
8. When prompted, press to save your modifications. Close VitaShell and reboot the PS Vita.
   • If your device does not have Ensō, you will need to manually launch and exit h-encore to enable homebrew
   • This is required to load the new kernel plugin added to ux0:tai/config.txt

Adding PSP Games

Any PSP or PS1 games downloaded from the Vita's PlayStation Store will automatically be put in ux0:/pspemu/PSP/GAME. Manually installing PSP homebrew will also go into this directory.

If you want to install ISO dumps of games, they instead go to ux0:/pspemu/ISO.

Adding Plugins

Installing plugins is exactly the same process as installing them on an original PSP.

• Transfer the plugins to ux0:/pspemu/seplugins with either FTP/USB in VitaShell or USB Mode in Adrenline.
• Add the file path of the plugin(s) to either vsh.txt, game.txt, and/or pops.txt depending on what the plugin can be used for.

Compatability List

When using the Adrenaline launcher, the vast majority of games will work just like an original PSP. However, a few currently do not work with it. Games on this list are known to have issues or not work entirely.
