How to Install FreeMCBoot 1.966 on PS2: Complete Guide
FreeMCBoot 1.966 is installed on a PS2 memory card, not flashed into the console itself, and once it is installed the console boots into a custom menu whenever that card is in the slot. You cannot install it on a completely stock console just by copying files from a computer, because the PS2 needs an existing way to run the installer program first. This guide walks through the full process: checking that your console can use FreeMCBoot, choosing an entry point, preparing a USB drive, running the installer, and checking the first boot.
Before you start: three checks that save most failed installs
First, check compatibility. FreeMCBoot works on most PS2 consoles, but not on late SCPH-90000 Slim models made from the third quarter of 2008 onwards, which have boot ROM version 2.30 or newer, and not on the PS2 TV. For those late Slims you need a different approach, covered in FunTuna and Fortuna for Late PS2 Slim SCPH-9000x. Datecode 8C is a transition period, so if your console falls in that window, check the ROM version rather than guessing from the datecode alone. See How to Check Your PS2 Model, Datecode, and ROM Version for the full method.
Second, back up your saves. Installing FreeMCBoot writes to a memory card, and formatting a card during installation erases everything on it. Copy any saves you care about to a second card or to a USB drive before you begin, and use a dedicated card for FreeMCBoot if you can. A second card for saves is good practice anyway, because it keeps your game saves separate from the launcher files.
Third, pick an entry point. An entry point is simply a way to run the installer program once on a console that does not have FreeMCBoot yet. The common options are a console that already has a softmod or a modchip, a cheat disc that can launch homebrew, FreeDVDBoot, or a PS3MCA memory card adapter connected to a computer. If you have none of these, ask a friend with a modified console to run the installer for you, or use one of the dedicated guides for your situation: Install FreeMCBoot with FreeDVDBoot (No Modchip) or Install FreeMCBoot from a PC with a PS3MCA Memory Card Adapter.
What you need
| Item | Why you need it |
|---|---|
| A compatible PS2 console | Late SCPH-90000 models and the PS2 TV need Fortuna or FunTuna instead |
| A PS2 memory card for the install | The launcher lives on this card; an official Sony 8MB card is the most reliable choice |
| A second memory card, if possible | For your game saves, kept separate from the FreeMCBoot card |
| A USB flash drive | To carry the installer files to the console, if your entry point uses USB |
| A computer | To extract the installer archive and copy files to the USB drive |
| The FMCB 1.966 installer files | From the download page |
For hardware, a blank official-style 8MB memory card is the safest starting point, since large third-party cards are the most common source of card problems. You can find a suitable blank card through this memory card link, and a simple USB drive through this USB drive link. Buy a blank card and install FreeMCBoot yourself; do not buy a card sold with software or games already loaded on it.
Step 1: Prepare the USB drive
Format the USB drive as FAT32 with an MBR partition table if your entry point loads files from USB. The PS2 is an old console with USB 1.1 ports, and it is famously picky about modern drives, so an older, smaller USB 2.0 drive often works better than a large, fast USB 3.0 drive. If the console does not see the drive at all, try a different drive before assuming anything else is wrong; drive compatibility is covered in detail in PS2 USB Drive Not Detected: MBR, FAT32, and USB 1.1 Issues.
Extract the FMCB 1.966 archive on your computer with an archive tool that handles 7z files, then copy the installer files to the root of the USB drive, following the folder layout in the package. Do not bury the installer inside extra subfolders you invented yourself. If your computer’s security software removes the installer file as soon as you extract it, that is a known false-positive pattern with homebrew executables, and the fix is covered in FMCBInstaller.elf Missing, Quarantined, or Archive Won’t Extract.
Step 2: Run the installer from your entry point
Boot the console through your chosen entry point and launch the installer program, usually named FMCBInstaller.elf. The installer presents install options, including a standard install for your own console, a multi-install option, and a cross-region option. For a first install on your own console, choose the standard install that matches your console. The cross-region option is a separate topic with its own failure modes, covered in Cross-Region FreeMCBoot Install Failed or Won’t Boot.
Read each screen before confirming, and do not switch the console off or remove the card while the installer is writing. When the installer reports success, exit it cleanly and restart the console with the newly written card in the slot. If the installer offers to format the card first, remember that formatting erases saves, so only accept it if you have already backed them up or are using a fresh card.
Step 3: Check the first boot
On restart, the console should show the FreeMCBoot menu instead of the standard browser, with the card still inserted. If it boots normally as if nothing happened, work through the checks in FreeMCBoot Not Booting or Black Screen on Startup: card in the correct slot, card compatibility, console model, and whether the install actually completed. A card that boots on one console but not another is often a region or model issue, not a broken card.
Once the menu appears, the core install is done. The menu itself is deliberately minimal at this stage, because the standard package does not bundle applications. The next job is to add the programs you actually want to use, such as Open PS2 Loader for loading your own game backups from USB, a network share, or a hard drive, and uLaunchELF for managing files on the card. Those steps are covered in Open PS2 Loader Setup: USB, SMB, and HDD Modes and Update OPL and Add Apps with uLaunchELF.
Frequently asked questions
Do I need a modchip to install FreeMCBoot?
No, not in the usual case. You need an entry point, which can be an already modified console, a cheat disc, FreeDVDBoot, or a PC adapter method. A modchip is one possible entry point, but it is not a requirement for most consoles.
Can I install FreeMCBoot on any PS2?
Almost any, with the known exceptions: late SCPH-90000 Slim models with boot ROM 2.30 or newer, and the PS2 TV. Those consoles need Fortuna or FunTuna, which triggers manually from the system browser instead of booting automatically.
Will installing FreeMCBoot damage my console?
FreeMCBoot does not rewrite the console’s internal BIOS, and removing the card restores normal behaviour. The realistic risks are losing unsaved data on a formatted card, and the general care needed when running any installer, which is why backups and a dedicated card matter.
Why is my FreeMCBoot menu empty after installation?
Because the standard package ships no applications. Add Open PS2 Loader, uLaunchELF, or other homebrew programs afterwards, following their own setup guides, rather than expecting them to appear automatically.
