    Hi

    I got a reply from Rick asking how these shops convert a single region dvd
    player to multi in a mater of minutes. How do they physicly do it? Do they
    short a IC pin out and it resets it or what? I have no intrest in doing it
    myself, just want to know how they do it.

    Many Thanks

    Alistair

    It's a firmware reprogram, the same way you update a system
    bios on a computer motherboard.

    Not always, there are machines that have an 'easter egg' in the firmware
    where a certain set of key-presses will either reveal a new menu or
    reset the region, there are also some that require a 'mod' chip to be
    fitted, AFAIK the chip is usually something along the lines of a
    Microchip 12C508 or some other small micro-controller. The chips appears
    to either modify the data in the configuration memory on the player or
    intercept/inject data into the (usually) I2C bus. There are also players
    that can have multi-region firmware programmed in as well, whether this
    is hacked firmware or something released by the manufacturer via a back
    door is unknown to me, but I would guess both happen.
