I haven't got this ready yet, but I am thinking about using the Memory Card Exploit or Slide Card.

After getting the file on my memory card, how do I load my back-uped PS2 game. I am guessing I just boot the disk up with LaunchElf like Swap Magic, but I am not really sure. Please help.

You're all wrong. You can boot PS2 games from the memory card exploit. I would know as I am using it at the moment. All you need is the Swap Magic elf and you can place that into your exploit when you make it. Then when you boot up the exploit, run the Swap Magic elf and use the refresh TOC method to play your backup PS2 games.

When a 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).

Triggering the exploit requires a way of installing the modified files to the Memory Card, which is not possible by normal means. Installation is accomplished either from a console (modified or with the exploit already installed), a Memory Card reader/writer, a disc swapping technique or through the use of some commercial programs allowing USB flash drive to Memory Card transferences, such as Code Breaker (versions 8 and higher) or Action Replay MAX, by transferring a modified System Settings save file.

In short, once the necessary files have been transferred to your memory card, you use a PS1 game to 'trigger' the exploit, and from there you can use homebrew software like uLaunchELF to execute ELF files to play backups.

@pryme_H,

You can't run games using the Swap Magic elf without a fliptop or slide tool. You need these two things to be able to put your backup in. If you press the eject button and place your backups into your PS2, the games won't work.
