Most of what is written below is taken directly from the developers personal website.


This is an Free Memory Card Boot (FMCB) installer. It was previously known as the "Unofficial FMCB v1.8C" installer.
No part of it was directly re-used from FMCB v1.7 itself, but parts of it were based or referenced from the code of FMCB v1.7.
The files in the fmcb-install folder are from Jimmikaelkael's PS3MCA project. Of course, I didn't include the questionable files which Sony claimed as a breach of their copyright.
Since FMCB v1.9 was born, the FMCB installer has been used for installing FMCB.

How To Use

  1. Download the archive linked to in the downloads section
  2. Extract the contents into a USB Mass Storage device (e.g. USB thumb drive, HDD).
  3. Launch the installer with your PlayStation 2 console
Option Description
Install Performs a normal installation of FMCB
Multi-Install Performs a "multi" installation of FMCB. A multi-installation can boot on all consoles of any region, and not only on the console it was installed with.
Uninstall FMCB Removes a normal installation of FMCB from a memory card.
Uninstall MI Uninstalls a multi-installation, turning it back into a normal FMCB installation.
Format MC Formats a Memory Card.
Dump MC Dumps a Memory Card to an image installer's directory.
Restore MC Restores a Memory Card from an image located in the installer's directory.
Shutdown Switches off the Playstation 2 console.
Exit Exits the installer and returns back to the OSDSYS menu.

Known Bugs

Known bugs:

  • None

Known limitations:

  • Some USB devices (i.e. Kingston) are known to be incompatible with PlayStation 2 homebrew software. To avoid a loss of data, please do not use them to store dumps from your memory cards.

Additional Notes

I've spent slightly over a hundred hours working on this, and I hope that it works well.... but of course, anything could go wrong - so I have provided a memory card dumping and restoration facility within the installer.

A dump of a memory card in slot 1 will get saved as mc0.bin, and a dump of a card in slot 1 will get saved as mc1.bin. The file will be saved to the directory where the main executable of this installer resides in. Caution! You can only make one dump of a card from each port. Making additional dumps will overwrite the previous dump.

Supported installation media:

  • USB devices only

== Warnings Against Potential Pitfalls ==
!!! WARNING !!! If you make a multi-install, do not delete any of the B*EXEC-SYSTEM folders or any of the OSD*.elf files inside them! Doing so might result in SEVERE data loss. Do not delete uninstall.dat from the SYS-CONF folder either, or you will probably be stuck with the multi-install files forever.

Lastly, read the included README file for more details.

Notes Regarding The Sources

The sources have been released. :) Check out the downloads section below.

Within the sources, I have created:

  • SECRMAN, a clone of the Sony Security Manager (SECRMAN) module that has card-binding functions (SecrDownload*).
  • SECRSIF, a clone of the Sony Security Manager SIF RPC server.
  • MCTOOLS, a RPC server module that provided misceallenous functions for the memory cards like dumping and restoration, and filesystem manipulation.
  • UDNL, the Updater module. Used for updating the IOP with newer modules (Which is only SECRMAN for this installer).

Hopefully, they will be useful for the homebrew community after their release.
