FreeMcBoot (FMCB)
FreeMcBoot (FMCB)
FreeMcBoot, usually shortened to FMCB, is a software-only modification that lives entirely on a PlayStation 2 memory card. When the console powers on, it scans inserted memory cards for special files before reaching the regular menu. FMCB plants those files so the system loads a custom launcher instead, giving you a homebrew menu without ever opening the console or soldering anything.
The key advantage
Because it is purely a softmod, FMCB costs nothing but a memory card and a way to write to it. Nothing inside the PS2 is permanently altered, so removing the card returns the console to a completely stock state.
Where it works
FMCB targets the system software baked into the console, not the boot ROM. It runs on the large majority of fat and slim PS2 models. However, the latest hardware revisions ship with a newer protokernel that the classic installer cannot exploit directly. On those units, people typically use a disc-based exploit first to write the memory card, or turn to a newer fork such as FreeMcBoot 1.97x built for wider compatibility.
Pros and cons
- Pro: reversible, free, and requires no hardware work.
- Pro: launches uLaunchELF and other homebrew straight from the card.
- Con: tied to the card, so a lost or corrupted card means a lost setup.
- Con: the very newest consoles need an extra exploit to bootstrap the install.
For most owners, FMCB remains the simplest entry point into PS2 homebrew. Once installed, it pairs naturally with a file manager so you can browse storage, copy saves, and launch applications immediately.
