Multi Region DVD

[Alistair]

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.
