Advanced User Guide for Free McBoot 1.8
Written by JNABK

GUI screen

Free McBoot is a method of running homebrew applications directly off a Memory Card as a stand alone loader. No boot discs or modchips are required once installed. You will however need to have a method to install FMCB to the MC. This guide assumes you have a method to install already, if not click the Installation tab above, choose how your going to install and return when ready to install FMCB.
*NOTE* This guide is written for use with version 1.8 and should not be used for previous versions, as some things wont apply to those versions!! Some example images are from the previous releases and are only examples to illustrate an option.
*NEW for v1.8
The Installer now has a GUI with much more informative screens to help you with your installation. Press left or right to select from the menu and press X to execute the selection. Pressing triangle displays a credits screen

Its up to YOU the user to add anything to the installer to use, so decide on what you want to do with Free McBoot once its been installed and then add the apps you want to use.

HDLoader    ........Free McBoot skin for HDL   skin must be patched to HDL before installing

You can also find most any app for the PS2 at 
Emulators, ps2 app skins,  Tools & Utilities, Online, Converters , cheat apps, and much more can be found at

Prepare  files for installation:
The Free McBoot Package contains the FREE_MCBOOT.ELF and an INSTALL folder. Only files/folders contained in the INSTALL folder will be used for the installation.

You can place the following files into the INSTALL folder's root:
  • BOOT.ELF    { uLaunchELF is the best file manager/ELF launcher available}
  • ESR.ELF        { used to run backups without the need to swap discs, patching required }
  • HDLOADER.ELF   { run games from an internal HDD, Slim users can not use this }
  • SMS.ELF    { best Media Player available }
These files will be copied to the MC's BOOT folder . Folders will not be copied to the BOOT folder.

Example of  how the folder structure should look when properly placing the files:

Exact filenames as shown
above are case sensitive with the default FREEMCB.CNF. Check that the file extension .ELF  is in fact in CAPS, or it will not display.
 If you use different filenames, then it wont work until you configure the FREEMCB.CNF  to use those filenames.  More info ...

These files will be listed and linked to run from the Sony main menu . More Info


The installer will calculate the amount of space that is to be used for your install and show the free space as well.
  It is important to watch the overall file size when adding apps to your installation folders.
 Also consider skins, roms,CNF files, images, etc...  will add to the size
if your using them from the MC.
Each of the folders included in the install package serve a purpose and should NOT be deleted unless you understand what they are for and can judge if they are necessary or not.
APPS - Details This folder is for any additional files you wish to add to your MC .
INJECT -Details Put your "DVDELF.BIN" or "EMBED.ELF" file here, they will be used for the  DVDELF injection. More info...
MODULES -Details This folder comes with  USBD.IRX  and  USBHDFSD.IRX files. These are required by Free McBoot to use a USB device.
FMCB_CFG -Details The FMCB_CFG.ELF is Free McBoot's Configurator (made by Suloku from psx-scene).

Free McBoot MUST be installed to a Memory Card and can not be copied off another.  A copy will only work on the MC it was installed on.
Cross Region installations  will not work!  This means installing  with a console from one region will not work on another console from a different region.

Installer Options:

Normal install will  install the  required system files for your console version its installed on.
Multi-Version install will install additional files for other console versions of the same region to work from the same MC.
Launch fmcb will load the newly installed Free McBoot .
fmcb configurator Launches the Configurator Application
format mc If you dont have anything worth saving on the MC, then format the card for a better chance of a successful install.

uninstall multi-version reverts a multi-install to normal install

*NEW for v 1.8
You now have the option to install to either MC from slot1 or slot2
choose MC slot

The Installer will detect if you have a BOOT.ELF to install, if no BOOT.ELF is found, you are given a chance to abort the install so you can put a BOOT.ELF in the proper location, as described above and in the correct file extension of all CAPS.
Or you can continue the installation without it, but you were warned, so dont say you werent!!
If you dont have a BOOT.ELF already present on your MC from an earlier install, you should add it to the INSTALL folder.

No BOOT.ELF found

A successful install should look similar to the below images:
