What is FMCB?
Free Memory Card Boot (FMCB) is a piece of homebrew software, which is designed to setup your PlayStation 2 console and provides you with means of launching homebrew software, without the need for any extra hardware, modifications to your console or dangerous tricks like the legendary swap trick.
FMCB was originally developed by Neme and Jimmikaelkael, but they have been kind enough to provide me with access to its source code, for me to make some improvements to it.
FMCB is installed onto your memory card. While clone/compatible memory cards may work, they are copies of a proprietary memory card, which often means that they aren't perfectly compatible. Please use clones/compatibles at your own risk.
FMCB will not allow you to boot games that you cannot already play. This means no playing of burned and imported discs.
What is FHDB?
Free Harddisk Drive Boot (FHDB) is basically FMCB that gets installed onto the PlayStation 2 console's HDD unit. It does everything like FMCB does, but is meant to be used with the Sony HDDOSD (Browser update v2.00).
Patched/modified copies of the HDDOSD may not work, although non-Sony disks are supported by FHDB itself.
***Whether the hacked HDD OSD supports non-Sony disks or not depends on whether it was modified to support non-Sony disks.***
Modifying or getting a pre-modified copy of the HDDOSD is not under this project, which is why that topic will not be discussed here.
Like with FMCB, FHDB will not allow you to boot games that you cannot already play. This means no playing of burned and imported discs.
