Installation On PSP

Installation from Custom Firmware

• If 6.61 PRO or ME is already installed.
• For any earlier CFW, update to latest 6.61 firmware and use instructions below for Official Firmware.
• Install DC-ARK (see bellow).
• Install New cIPL (see bellow).
• PowerOff console and power it back on while holding L button.
• Use DC to do a fresh and full install of 6.61 ARK.

Installation from Official Firmware

• If no custom firmware is installed (PSP is original).
• Copy ARK_01234 folder into /PSP/SAVEDATA/ folder.
• Copy ARK_Loader folder into /PSP/GAME/ folder.
• Launch ARK Loader. It will install ARK modules on PSP Flash and boot the CFW.
• At this point ARK will work as a Live CFW, meaning that ARK Loader will need to be run every time the console is turned off or rebooted.
• To convert ARK into a Permanent CFW you can use cIPL.

Permanent CFW via cIPL

• Works on all PSP models, including testkits and devkits.
• Installer will choose the correct version according to your model.
• Some models can install either the Classic cIPL or the New cIPL.
• Copy ARK_cIPL folder to /PSP/GAME/ and run the program.
• Press the corresponding button in the installation page to install or remove the cIPL patch.

Full Flash and Classic Installations

• This only make sense when combined with a permanent intallation (cIPL). It doesn't make sense on PSP Go with a healthy Internal Memory.
• This allows you to install and use all of ARK's features on the console's internal flash memory, except for Custom Launcher and translations.
• Copy ARK_Full_Installer to /PSP/GAME/ and run it from ARK. It will install some extra files into the console's flash.
• If the Custom Launcher is not available (i.e. you delete the ARK savedata or remove the memory card), PRO Shell will take its place.
• When no savedata folder is available the default ARK path used to store settings will be ms0:/SEPLUGINS/.
• Even if files are stored in the console's flash memory, the ones in the savedata folder will still take priority in loading.
• If at this point you get rid of ARK's savedata then you will have a Classic Installation (ARK will behave much like your Classic CFW such as PRO or ME).

Time Machine and Despertar del Cementerio

• Time Machine allows the ability to boot the 6.61 firmware and ARK entirely from the Memory Stick.
• Despertar del Cementerio allows the ability to revive a bricked PSP when used in combination with a Pandora or Baryon Sweeper.
• You can install DC-ARK either using a PSP or a PC (Windows, Mac and Linux).
• On PSP you need to be running a CFW to install DC-ARK (ARK itself or any other).
• Copy the ARK_DC folder to the /PSP/GAME/ folder and run the installer from the XMB.
• Copy the 6.61 Official Firmware Update by Sony renamed to 661.PBP at the root of the memory stick.
• Follow the instructions to install DC-ARK and create a magic memory stick.
• On PC, you need Python 3 and run MagicMemoryCreator with admin/root privileges.
• You can use New cIPL to boot into DC-ARK by holding L-trigger when powering on.
• Or use a Pandora or Baryon Sweeper in combination with your newly created Magic Memory Stick to boot up Despertar del Cementerio.
• On compatible models, you can use Advanced VSH Menu to create a Pandora Battery.
• From here you can either boot ARK from memory stick, install 6.61 Firmware with ARK on the NAND or install 6.61 Official Firmware.

Installation On PS Vita

There are two types of installation types on PS Vita. You can use either one or both.
Stanalone works on top of the original unmodified pspemu.
You an also run ARK within Adrenaline to achieve a Hybrid CFW.

Standalone (Official PSPEmu)

• Works on Firmware 3.60 up to 3.74, requires Henkaku/h-encore or any native hack.
• Download and install NoPspEmuDrm (you can use AutoPlugin).
• Copy FasterARK.vpk from PSVita/ folder anywhere on your vita and install using VitaShell.
• Launch FasterARK and wait for the install process to finish.
• Both ARK and ARK-X bubbles will appear in Live Area.
• Use the ARK bubble for PSP games and homebrew. It can play PS1 but with limitations related to sound playback.
• Use the ARK-X bubble for PS1 games without any sound limitations.
• Once ARK bubbles are installed, you can delete FasterARK.
• To exit from a game or homebrew back to the custom launcher, press L+R+Down+Start (on ARK-X use L2+R2+Down+Start or L1+R1+Start+Down for VitaTV).
• NOTE: Some features are not available in standalone installations, mainly the official Sony XMB, and Force Extra RAM setting is known to be unstable.
• NOTE: If you want to have an ARK bubble that works on Official Firmware you must use ChovySign with a valid license. Instructions in Wiki.

Adrenaline (Patched PSPEmu)

• Works on Firmware 3.60 up to 3.74, requires Henkaku/h-encore and Adrenaline (Isage's fork is recommended, but original will work too).
• (Skip this step if Standalone is already installed) Install ARK_01234 folder into /PSP/SAVEDATA/ folder.
• Install ARK_Loader folder into /PSP/GAME/ folder.
• Use Adrenaline Bubbles Manager to create an autoboot bubble for ARK Loader: https://github.com/ONElua/AdrenalineBubbleManager/releases
• Note: this does not permanently modify Adrenaline in any way.

Updating ARK

There are three ways to update ARK:

• Option 1: Use the System Update ( ARK-4 Updater ) feature in the XMB. Requires your PSP/Vita to be connected to the internet.
• Option 2: Copy the UPDATE folder to /PSP/GAME/ and run it.
• Option 3: Copy ARK_01234 folder and (on PSP) run ARK Loader again to install new flash0 files.

Warnings

• ARK comes with no warranty whatsoever. It was designed to be noob-proof, however it is possible for the universe to create an even greater noob capable of using ARK to destroy the Earth (or his PSP). I cannot be held responsible for this.

• ARK may cause ejectile malfunction if your hard drive is not hard enough.

• If this software malfunctions, you can turn it off and on again.

• You may be shunned for not reading the Wiki.
