Adrenaline mimics the official Sony PSP emulator on the Vita, it will boot up as if you are playing the PSP on 6.61 custom firmware. This tutorial will show you how to install Adrenaline through VitaShell, make Adrenaline download a hacked PSP firmware so you can use it to play your backups, fix a known bug on Adrenaline, and where to put your PSP and PS1 backups.

Files Needed

Adrenaline: GitHub Link 
VitaShell: GitHub Link

Step 1: Enable View Hidden Folders.

Show Hidden Folders

  • Go to View / Options /Change folder
  • Search options / View / and select “Show hidden files, folders, and drives
  • Make sure to uncheck “Hide protected operating system files (Recommended).

  • For Mac Users, you can use CMD + SHIFT + . to enable hidden folders and again to turn off the view.

Step 2: Launch Vitashell and Connect via USB.

Memory Card

  • Launch Vitashell, press Start and change “SELECT button” to USB.
  • Press O to cancel main settings and then press SELECT to connect your Vita to your PC.
    Note: If you are using SD2Vita, change the USB device to SD2Vita.

Step 3: Move the Adrenaline.vpk File to the Vita.

Adrenaline PT3

  • Go to the folder where you stored the Adrenaline file.
  • Move it to the App folder that just popped up when you connected through the USB.

Step 4: Use VitaShell to Install Adrenaline.

  • Press O to cancel the USB connection.
  • Go to ux0:app folder.
  • Press X on the Adrenaline.vpk file.
  • Press X to confirm the install.
    Note: You can delete the Adrenaline.vpk file after the installation if you need space.

Step 5: Go Back to the Home Page and Launch Adrenaline.

  • Go to the home page and turn on your WiFi, this will allow Adrenaline to download the PSP firmware.
  • Then click on the Adrenaline bubble and launch it.
  • You will get a message that says “Press X to download the PSP 6.61 firmware” so press X to download.
  • If you accidentally push any other button besides X, Adrenaline won’t download and you will need to delete Adrenaline and install it again to get it to download.

Step 6: Launch Adrenaline Again.

  • Launch Adrenaline and this time it will say “Press X to install the PSP 6.61….”
  • Press X and let it install.
  • Once it is done “Press X to boot the PSP XMB.
  • You will then be launch into the PSP interface, set up your PSP and enjoy!

Step 7: Fix Adrenaline Double Launch Bug.

  • Adrenaline has a bug that requires users to press Adrenaline twice to get it to launch.
  • Go to your tai folder (if you are using Sd2Vita your tai folder should be in ur0:tai) and press X on config.txt.
  • Go down to *KERNEL and press “Insert empty line” and type in “ux0:app/PSPEMUCFW/sce_module/adrenaline_kernel.skprx” without the quotes.
    • This will always be ux0.
  • Press O to get out of the text field and press O again to get a prompt to save your modifications.
  • Press X to save.

Bonus: Where to put Your PSP Backups.

  • Exit out of Adrenaline (Hold the PlayStation button then click on settings next to Adrenaline, Exit PspEmu Application).
  • Go to VitaShell and connect through USB again.
  • For the folder that just popped up, go to pspemu folder and create an ISO folder in there.
  • Transfer your PSP ISO here.
  • Go back into Adrenaline.
  • Go to Game/Memory Stick to play your PSP backups.Note: If you ever had a PSP, you know you can also put other emulators. However, the PSP and PSX are going to offer the best emulation.

Bonus2: Where to put Your PS1 Files.

  • Go to VitaShell and connect through USB again.
  • For the folder that just popped up, go to pspemu/psp/game (if these folders are not available, create them).
  • In order for Adrenaline to recognize your PS1 Eboot (format of the rom) you need to put the Eboot inside a folder.
  • In this guide, I have an Eboot and I put it inside a folder called GT3E52 (This is the game ID but it can be called anything).
  • Go back into Adrenaline and go to Game/Memory Stick.

    1. I have a Model 1001 with v3.60, HENkaku, Enso and VitaShell. If I do what you say here and then do what you say on your SD2Vita page (making the SD2Vita microSD card ux0:), will I then have my PSP ISOs and PS1 EBOOT roms on my larger microSD card? Or, do I do the SD2Vita first and then this? All that matters to me is having all my PSP & PS1 roms on the microSD card and not Sony’s Memory Card because God of War Chains alone is 1.45GB. Which do I do first – your SD2Vita page or this Emulators page? Also, you didn’t mention anything about .cso (compressed ISOs) Can they be used?

      1. You should install the sd2vita first to use your microSD card. If you have the actually iso and eboot files then you can follow my guide on where to put those (the default is ux0 which should be your microSD card after you install sd2vita). The default settings is to read PSP/PSX games off of the microsd card, so it is actually more steps to take if you want it on the Sony memory card. I don’t know how well .cso files will work on Adrenaline but it should be in the same folder as the iso files.

  1. SO I’m stuck at step 6, I install the psp 6.61, I keep getting error code C1-2858-3, I’ve download the firmware 6.61 from the internet and done a Manuel download. Idk why adrenaline doesn’t load… I have the henkaku hack installed on 3.63 firmware.

    1. Did you meant to say you are on 3.68 firmware? Since you manually downloaded the 6.61 firmware did you put that file in ux0:app/PSPEMUCFW?

    1. I will when it is available. As of right now, you can’t hack the vita on 3.70 but should be able to sometime in late 2019.

  2. Hello,
    Is it normal that with Adrenaline, the PSP XBM menu doesn’t looks clear as an original PSP but has like a compressed, low resolution appearance ?

    Many Thanks

  3. Hi my console has wifi module permanently damaged and unable to repair…
    therefore in the step of download PSP 6.61 is unable to go through.
    I wonder if there is any way I could download it with a computer and move to somewhere required and continue with the setup?
    Much appreciated!!

      1. Hi I moved some games from my laptop to pspemu and now they have disappeared and the memory has been allocated like they are there. Any idea why this is and how to get back lost memory? Thanks in advance

  4. i placed psp rom tekken 8 is the ux0/pspemu/iso and it s showing on the adrenaline game which opens only the trailer and replay trailer in a loop..pls help

    1. I don’t think there is a tekken 8, sounds like a fake but the fact that you can play anything shows that you are putting it in the correct place.

  5. Hello, I receive the error 0x80010002 using a sd2vita (with enough space, recognized by the system, with working games on it) when i try to install vpk files
    I just finished setting the sd2vita, maybe i forgot to set up more stuff on it?

    1. Are you sure you transferred everything from your old memory card to sd2vita, make sure to enable hidden folders when you transfer everything over.

  6. I’m having an insane amount of trouble loading roms with Adrenaline, specifically through SNES9X. Can you put a tutorial for that? perhaps I did something wrong

    1. Yes for each emulator, you have to put the roms into a different folder. I believe for SNES roms you need to put it in ux0/data/SNES9x.

  7. Hi,

    I just installed H-Encore on my vita, which is on 3.68.
    All seemed to work fine, but then I tried to install Adrenaline and it does not work at all.
    It asks for extended permissions, but there is no possibility to check “Enable unsafe homebrew”.
    The only options available are Theme, USB device, Select button, disable auto-update, restart vita shell and the likes of power, reboot, power off and standby.
    Do you have a solution? Your help is much needed and appreciated.

    1. It sounds like you need to run H-Encore again. Since you are on 3.68 you have to run H-Encore every time you shut off your Vita.
