A.5.What is the “ Independence Exploit” and how doesit help me?The Independence Exploit is a softwarebased exploit that allows a PS2 to run unencrypted and homebrew applications(such as SMS) from the memory card. A description of whatthe exploit actually is can be found.The Independence Exploit is one of the techniques that can be used totrick your PS2 into running SMS. Normally your PS2 does not allow youto run unencrypted programs, and this protection is in place mainlyto reduce the spread of copied games. When it comes to legitimateopen source projects like SMS, the protection only stands in the way ofrunning SMS. When installed, the Independence Exploit allows the user torun a specific application stored on the memory card. Often the chosenapplication will be an ELF launching program (a file browser) whichthen allows further applications to be launched.
The Exploit itselfis executed by inserting a chosen PS1 “ trigger disc”,inserting a memory card with specially modified files on it, andthen pressing reset. Tutorial of how to get the correct speciallymodified files onto your memory card can be found.The recommended approach is to use the tutorial to install an ELF launchingprogram and an FTP server. Then you can use the FTP server to installas many other applications (ELF files) as you want.
It also then allowsyou to make backups of all your saved games which is handy for thosestrange people who still use their PS2 to play games!The exploit is significant to SMS users since it is one of the cheapestways of running SMS, requiring no additional hardware other than aPS2, a memory card, and an original PS1 game.

The PS2 Independence Exploit allows the execution of homebrew programs on an unmodified PlayStation 2.Exploit detailsWhen a PlayStation (PS1) game is loaded in the PlayStation 2, the console looks for a file called TITLE.DB which, if present, is located in the Memory Card's directory BxDATA-SYSTEM (where x is a letter corresponding to the console's region -e.g.: E for the EU, A for the USA or I for Japan, this directory corresponds to the System Settings save). This file is a database of special options to be applied to specific PS1 games for their correct operation.The exploit relies on creating a deliberately incorrect entry inside this file, which triggers a buffer overflow and, combined with a small stub loader located in the file, allows the execution of unencrypted code from the Memory Card upon the insertion of a specific PS1 game.
Normally, only programs encrypted by Sony, such as the DVD player, will run from the Memory Card.The discovery of this vulnerability in the PS2's software opens up the possibility of running programs created by the PS2 homebrew developer community without the need for a modchip or disc swapping techniques (e.g. CogSwap or Swap Magic).These swap techniques use a hardware exploit of the PlayStation 2. They use a tool to open the disc drive tray without the PS2 knowing on 'fat' units or using a different tool to push the 'flap closed' sensor on slimline units.
