    • Burn patched games onto a DVD and play them using ESR Disc Patcher.
    • Load games from a USB stick with OPL*

    • Play games from an internal hard disk using OPL.
    • Load games from your computer over the network with OPL.
  • PS1 Games: Thanks to POPStarter, you can even play your beloved PS1 games using a USB key.

FreeMCBoot: How Does It Work?

FreeMCBoot revolutionizes the PlayStation 2 (PS2) gaming experience by exploiting a loophole in Sony’s firmware update mechanism. Unlike its successors, the PS3 and PS4, the PS2’s firmware is stored on a read-only memory (EEPROM) chip, making it impossible to update. However, Sony introduced a workaround wherein the PS2 checks for software updates on startup, either from a memory card or the hard disk.

For instance, early Japanese models of the PS2 lacked the ability to play DVD Videos. Sony provided a CD that allowed users to install DVD Video player software onto their memory cards. Upon startup, the console automatically loaded this software from the memory card, enriching the PS2’s capabilities. Although later models incorporated the DVD Video player directly into the ROM, Sony continued to distribute CDs with updates for compatibility purposes.


Here’s where Sony made a crucial mistake with their MagicGate protection system. While the PS2 diligently checked for a valid digital signature in the header of the DVD Video player’s .KELF file, it failed to verify the file’s integrity. This oversight opened the door for users to inject their own code into the .KELF file without detection. The console would still validate the .KELF file and unknowingly execute the injected code.

And thus, FreeMCBoot was born. It exploits the vulnerability in the DVD Video player’s .KELF file, injecting its own code to hijack the PS2’s startup process. When the PS2 loads the .KELF file, it unknowingly executes the FreeMCBoot code instead of the original DVD Video player software. This grants users unprecedented control and freedom over their PS2 consoles.


With FreeMCBoot, you can unlock the hidden potential of your PlayStation 2, enjoying game backups, homebrew applications, and an enhanced gaming experience. By exploiting Sony’s firmware update mechanism, FreeMCBoot injects its own code, giving you control over your console. Discover a fresh menu, play game backups, enjoy PS1 games, and explore exciting homebrew applications. Install FreeMCBoot on your memory card using various methods, and unleash the power of your PS2. Get ready to take your PlayStation 2 gaming to a whole new level with FreeMCBoot!
