Compiling ARK ( For Developers )

Build script will allow you to use the correct SDK that ARK was built with.

• Docker container: docker pull docker.io/krazynez/ark-4:latest

These are utlized either with cloning the repo or using the Docker container

• Release: ./build.sh
• Debug: ./build.sh --debug
• Manually: install the oldest possible SDK (ideally the one used to compile M33), then run make

Use -h or --help to show all available flags

On PSP

Online PSP Installer

For an easy deployment of ARK on a PSP connected to the internet, you can follow this video

Manual installation

The instructions are as follows:

• Move or copy ARK_01234 folder into /PSP/SAVEDATA/ folder.
• Move or copy ARK_Loader folder into /PSP/GAME/ folder.
• Launch ARK Loader. It will install ARK modules on PSP Flash and boot the CFW.

Live CFW

• Delete FLASH0.ARK from /PSP/SAVEDATA/ARK_01234 to prevent flashing files every time you reload the CFW.
• Run ARK Loader when you boot up the system after you've fully turned off or hard reboot the device to re-enable ARK.

Permanent CFW via new cIPL

• Works on 1K models, 2K models and early 3K models (1g, 2g and 3g).
• Only works on 6.61. Does NOT work with Testing Tool or Development Tool firmwares.
• cIPL will not install if not compatible, so no risk if running it even if you're unsure what specific model you're using - if not compatible, use Infinity 2 instead.
• Move or copy ARK_newIPL folder to /PSP/GAME/ and run the program.
• Press the corresponding button in the installation page to install the cIPL patch.
• Warning: unlike classic cIPL, the new method can't be easily uninstalled.

Permanent CFW via classic cIPL

• Only works on 1K models and early 2K models (those compatible with Pandora).
• Works on 6.60 and 6.61, including Testing Tool firmware. Does NOT work with Development Tool firmware.
• cIPL will not install if not compatible, so no risk if running it even if you're unsure what specific model you're using - if not compatible, use Infinity 2 instead.
• Move or 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.

Permanent CFW via Infinity

*RECOMMNEDED* If already using another CFW with Infinity < 2.0.5, use chronoswitch to reinstall 6.60/6.61 OFW (Offical Firmware). If you do not when launching Infinity it can just lock your PSP up causing Infinity to not work properly (not harmful, just not properly). Then proceed with intructions. You can still bi/tri boot your CFW afterwards.

• Works on all PSP models on 6.60 or 6.61 firmwares.
• Copy or move the EBOOT.PBP (or EBOOT_GO.PBP renamed to EBOOT.PBP if using a PSP Go) from the Infinity folder found in the ARK download into /PSP/GAME/UPDATE.
• Run theInfinity app using Official Firmware to run the initial installation. If you previously had and older Infinity installed when prompted to update please do, as our Infinity version includes the ARK patches to autoboot.
• Run Infinity a second time to configure autoboot by selecting ARK within the Infinity app. Run the ARK CFW again to activate. ARK will now be automatically activated on boot up.

Full Flash Installation

• This allows you to install and use all of ARK's features from flash0, allowing you to entirely remove the ARK_01234 savedata folder or memory stick.
• Copy ARK_Full_Installer to /PSP/GAME/ and run it from ARK.
• It will install the necessary modules into the console's flash.
• This installation will make use of Classic Recovery Menu when the regular one is not available.
• Custom Firmware settings and other Custom Firmware files are installed in ms0:/SEPLUGINS/, which is used as the default ARK path when no savedata folder is available.

Time Machine and Despertar del Cementerio

• Time Machine allows to boot the 6.61 firmware and ARK entirely from the Memory Stick.
• Despertar del Cementerio allows to revive a bricked PSP when used in combination with a Pandora or Baryon Sweeper.
• To install DC-ARK you must first format the memory stick leaving enough space for the boot sector. You can use PSP Tool to do this.
• You also 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.
• Follow the instructions to install DC-ARK and create a magic memory stick.
• On compatible models, use Advanced VSH Menu to create a Pandora battery.
• Use a Pandora or Baryon Sweeper in combination with your newly created Magic Memory Stick to boot up Despertar del Cementerio.
• 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.
• Note that installing 6.61 firmware with ARK requires a cIPL-compatible PSP (1K and early 2K).

RECOVERY

There are various ways to recover from a bad installation, usually result of bad configuration or misbehaving plugins, which may lead to crashes and even bricks.

Recovery Menu =

This option allows you to boot up a Recovery App with settings and plugins completely disabled to prevent issues. You can use this app to change settings, plugins and use a file browser for various recovery operations.

The Recovery App is installed on Memory Stick located at /PSP/SAVEDATA/ARK_01234/RECOVERY.PBP and can be changed to just about any homebrew in PBP format.

To load into the Recovery App you must hold the R trigger while turning on the PSP console or running ARK Loader. You can also do the same when running any of the Bubbles on PS Vita, either Adrenaline or Standalone (except for ARK-X).

When using a Full Installation on PSP and no Recovery App is available, ARK will load the Classic Recovery Menu from flash0, which includes PRO Shell, a minimalistic File Manager and Launcher.

Classic Recovery

Pro Shell

Vanilla Mode

If the Recovery App is unavailable (i.e. Full Installations), or for a better/easier diagnostics, you can run ARK in Vanilla Mode, which temporarily disables settings and plugins when running ARK or booting any game.

This will load the XMB as original as possible but you can still use features such as the VSH Menu or XMB Control (which will let you reconfigure all your settings and plugins), it also works for games.

To enable Vanilla Mode simply hold select and/or start during bootup or gameboot to disable settings and plugins respectively.

The effect of Vanilla Mode is temporary and goes away on the next game boot or reboot unless you enable it again.

Official Firmware (for PSP Permanent Installations)

For any PSP user that has a Permanent installation (i.e. Infinity or cIPL), you always have the option to boot the console in Official Firmware mode, which completely disables all Custom Firmware functionality until the next full reboot.

Pandora or Baryon Sweeper (for PSP)

If the console is Bricked and none of the above helps recovering the system, the last resort is to use a Pandora Battery or Baryon Sweeper in combination with a Magic Memory Stick.

You can find steps to install Despertar del Cementerio for Pandora models in this document.

For Baryon Sweeper users, you can use this tutorial: https://www.psx-place.com/threads/update-baryon-sweeper-unbrick-psp-1000-2000-3000-psp-slim-04g-07g-09g-psp-street-11g-model.32503/

Customization

Advanced VSH Menu Options

The default VSH menu packaged in ARK_01234 is a simplified, easier to use version of classic VSH menus. To have a more classic VSH menu with more advanced features you can select the Advanced VSH Menu from within the simplified VSH menu.

Some of the features available in Advanced VSH Menu include:

• Change USB Device mount (Memory Stick, Flash, UMD).
• Protect Flash in USB Device mount.
• View available ISO drivers.
• Mount UMD Video ISO.
• Change Foreground/Background VSH Menu colors.
• Convert battery from normal to pandora and viceversa.
• Activate flash and WMA playback.
• Swap X/O buttons.
• Delete hibernation (PSP Go paused game).
• Convert classic plugins to the new ARK format.
• Boot Random ISO.

And more.

Installing on PSP Flash:

WARNING: for advanced users only, do not attempt this if you're not familiar with the PSP flash.

By default, ARK's VSH Menu is installed on the Memory Stick (in /PSP/SAVEDATA/ARK_01234/VSHMENU.PRX). This has the limitation that you won't be able to access VSH menu without a memory stick. If you want to permanently install VSH Menu you need to copy VSHMENU.PRX to somewhere on your computer and rename it to ark_satelite.prx, which you can then copy to PSP's flash0:/vsh/module/, you can use the VSH Menu itself to enable flash0 via USB. The final path should be flash0:/vsh/module/ark_satelite.prx. You can also achieve the same result by using the Full Installer.

NOTE: even if you install VSH Menu on flash0, the one installed on Memory Stick takes precedence in loading.

Installing Plugins

The easiest method to install a plugin is to simply copy its .prx (and other files/folders the plugin needs) to its default installation folder (typically /SEPLUGINS/ folder) and navigate to it using the File Browser (built into Recovery Menu and Custom Launcher). Upon opening the .prx file, you will be given the options to select the runlevel, or type the game ID, where the plugin loads.

From there you can use the XMB or Recovery Menu to configure or remove your installed plugins.

Alternately, you can manually install plugins by creating a file called PLUGINS.TXT in the /SEPLUGINS/ folder and/or ARK's savedata folder.

If coming from PRO/ME you can Import them from the Advanced VSH Menu section.

To install plugins use the comma-separated format (CSV). Where the header is: runlevel, path, switch. A few samples:

• game, ms0:/seplugins/cwcheat/cwcheat.prx, enabled
• pops, ms0:/seplugins/cdda_enabler.prx, 1
• vsh, ms0:/seplugins/cxmb.prx, true
• ULUS10041, ms0:/seplugins/lcscheatdevice.prx, on

You can enable plugins on more than one game:

• ULUS10041 ULES00502, ms0:/seplugins/cheatdevice_remastered.prx, on

You can use the following keywords to enable a plugin:

• 1
• on
• true
• enabled
• Anything else disables the plugin

You can use the following keywords to tell ARK when the plugin loads:

• all/always: if either of these keywords are used, the plugin will always load.
• psp/umd: plugin should only load on retail games (UMD/ISO/PSN).
• homebrew: plugin should only load on homebrews.
• game: plugin can load on both retail games and homebrews.
• psx/ps1/pops: plugin only loads in PSX games.
• xmb/vsh: plugin only loads in the XMB.
• launcher: use this if the plugin should only load in the custom launcher.
• game ID: if you specify a game ID (i.e. SLUS000000), then the plugin will only load on that game.

You can also disable a plugin on certain games where they might be problematic. To do so, just add a disable line for the specific game ID after the enable line. For example, enable cwcheat on all retail games except for GTA LCS (US) and GTA VCS (EU).

• psp, ms0:/seplugins/cwcheat/cwcheat.prx, on
• ULUS10041 ULES00502, ms0:/seplugins/cwcheat/cwcheat.prx, off

Some noteworthy plugins that are compatible with ARK include (but not limited to):

• CXMB.
• Leda.
• PopsLoader V3 and V4i.
• Custom Firmware Extender.
• PSPLink.
• GTA LCS and VCS cheadevice (including the remastered version).
• CWCheat.
• pspstates kai.
• XMB Item Hider v1.3-r3
• DayViewer.
• Categories Lite.
• CDDA Enabler.
• PRO Online.
• PSP 3D.
• ZeroVSH Patcher.

Configuration and Settings

You can use the XMB and/or the Recovery Menu to easily handle CFW settings. However if you prefer you can also manually handle the settings yourself.

You can create a SETTINGS.TXT file using the same format as PLUGINS.TXT to enable/disable some CFW functionality on different parts of the system. Configuration settings you can use in ARK include:

• overclock: use this for better performance at the expense of battery time. Sets CPU/BUS speed to 333/166.
• powersave: use this for better battery life at the expense of performance. Sets CPU/BUS speed to 133/66.
• usbcharge: enables USB charging wherever you want.
• launcher: replaces the XMB with a custom menu launcher.
• disablepause: disables the pause game feature on PSP Go.
• highmem: enables high memory on models above 1K. You should only use this on homebrew runlevel as retail games were not meant to use the extra memory, and this can cause issues with cheat devices or other plugins that expect games to have their data at specific memory addresses.
• infernocache: enables cache for Inferno driver, improving performance of some games.
• oldplugin: enables old plugins support on PSP Go (redirects ms0 to ef0).
• skiplogos: skips the coldboot and gameboot logos.

You can use the same runlevels as used in plugins to tell ARK when the settings take effect (all/always, umd, homebrew, game, pops, vsh).

For example, you can overclock to highest CPU speed like this:

• always, overclock, on

Another example, overclock only on games, use powersaving on VSH:

• game, overclock, on
• vsh, powersave, on

This also allows you to enable settings on specific games:

• ULUS01234, overclock, on
• ULES01234, powersave, on

ARK comes prepacked with a very powerful launcher with a built-in file browser and highly customizable.

Some of its features include:

• Playback of ISO and all CSO formats with PMF video preview.
• Playback of UMD game discs.
• Categorized and organized game menu by PSP Games, PSP Homebrew and PS1 Games.
• Ability to scan savedata folders for games.
• Compatibility with old VHBL, ARK-2 and TN-CEF file names and folder paths.
• Ability to copy, move or delete entire folders.
• File browser has built-in FTP client, allowing you to browse and copy files from another PSP.
• FTP server and client can run simultaneously.
• Ability to mount UMD Video ISOs using the file browser.
• Ability to extract .zip files (up to highest compression) and .rar files (standard compression).
• Ability to edit text files (.txt, .cfg or .ini).
• Ability to install Plugins via the file browser.
• Different background animation effects.
• And more.

You can however change it to whatever you please. You can change the theme used by both the custom launcher and recovery menu by replacing THEME.ARK with your own.

Custom Themes

You can install themes within Custom Launcher (and Recovery Menu). Just place the themes folder anywhere on your PSP and use the file browser in the Custom Launcher to select which theme (THEME.ARK) you would like to install. By selecting it a submenu will pop up asking to install it or to preview the theme without installing.

History

Despite being a relatively new Custom Firmware for the PSP, ARK has quite a history that goes back to the early days of the PS Vita scene.

ARK is a CFW that started as a port (more like rewrite) of PRO CFW to the PS Vita (named PROVITA) created by the original Team PRO members (Coldbird, Liquid Snake and Neur0n). After the original team left, the source code of PROVITA was handed over to me (Acid_Snake) and my long time scene friend qwikrazor87.

We quickly began a huge process of rewriting and restructuring code, more specifically a much more robust dynamic patching algorithms that would work on any 6.6X based firmware (including all Vita's ePSP firmwares). Thus ARK-2 was born.

Soon after, qwik, thefl0w and I began working on PSX exploits, which resulted in TN-X and ARK-3 (never publicly released).

Because the original PRO CFW hasn't been updated or maintained in a while, and it has become a little bloated and hard to work with, I decided to start working on porting ARK to the PSP since the core elements of the CFW are compatible with PSP 6.60 and 6.61 with minor changes.

After lots of work getting the same ARK binaries to properly work on both PSP and Vita, I am proud to announce that the release of ARK-4 is finally here!

Changelog

• ARK-1: original port/rewrite of PRO CFW for the PS Vita. Codenamed PROVITA. Source code can be found here: https://github.com/PSP-Archive/ARK-1-PROVita-
• ARK-2: dynamic patching allows it to work with most of PS Vita firmwares. Source code can be found here: https://github.com/PSP-Archive/ARK-2
• ARK-3: device-specific runtime allows ARK to run in multiple scenarios (ePSP and ePSX). Source code can be found here: https://github.com/PSP-Archive/ARK-3
• ARK-4: ported to the original PSP. Huge amounts of improvements and fixes over previous versions.
