This is my first post on pprune, so I hope it it is well received, I'm easing myself in gently, with a post on Playstations, before I go on to aircraft related matters.
As far as I am aware, the Asian Playstation 2's would need Chipping, to work with European Games, it's not an issue of the ouput, but that the games are actually 'regionalised'. The chipping was realatively easy on the PS 1's but I don't know anyone who has done it to a PS 2. I have seen chipped Japanese PS'2's offered for sale on the internet so it is definitely possible.
I hope this is of some use to you.
