Modwright has an upgrade to multi-region for the 205.
That’d be way expensive!  Though if I had the money, I’d do it.

i did find what sounds like a good way to do it here:


This modification is send from The Netherlands or USA, depending on your shipping address.
This is a modification for the OPPO UDP-203/205 External kit Blu-ray player. After installation it will enable the player to show movies with a different region. This means for example that a region 1 movie will play on a region 2 player, without giving the region code or protection error.

Installation of this modification is quick, very easy and can be done within 20 seconds.
!!! NO SOLDERING NECESSARY !!! Just plug it into the Rs232 port on the rear of the player.


Sounds really easy!  

Anyone done this?  Does it work?
