1.50 Kernel Addon

Introduction

This is an ARK extension that installs the full 1.50 kernel on Memory Stick and allows to use it when loading legacy 1.50 homebrew. This gives us virtually full compatibility with all legacy 1.50 homebrew, with irShell being the only one with issues.

Pre-requisites

• You can only use this on a 1K model PSP. It does not work on other PSP models or PS Vita.
• Needless to say you need enough space on your Memory Stick (about 64MB).
• Your PSP console must be running the latest ARK-4 CFW.

Installation

• Install DC-ARK using the steps provided in the wiki.
• Copy ARK_150Addon from the PSP folder of the ARK-4 zip release onto /PSP/GAME.
• Download 1.50 OFW and place it on the root of your memory stick. ms0:/150.PBP
• Run the ARK 1.50 Addon installer on the PSP.

Usage

• Copy your legacy 1.50 homebrew to the /PSP/GAME150/ homebrew.
• Your legacy homebrew will show up in the XMB as a regular homebrew and can be booted as any normal homebrew.
• ARK already takes care of detecting the 1.50 Addon and the legacy homebrew, booting into 1.50 kernel for the homebrew.
• When the legacy homebrew exits back to the XMB, ARK will automatically reload back to the regular 6.60/6.61 firmware.
