Ok, i have bought an american PS2, and i am trying to use it in the UK.
I have bought a power adapter and a n-PAL converter, which is supposed to convert NTSC signal into PAL.. it is basically a block which has 3 holes for the 3 leads from the ps2 cable , and then the other side has a scart, which should go into the tv set.
so i plug everything in, i have the original disc for a game, and i start the ps2, and it loads, and everything works fine, but the screen is green with lines across it.
wish i could help but i have never even seen that product before.
But you will need some kind of converter, or buy a top quality mod chip like DMS4 Pro that has force modes to force all games into PAL or NTSC which will work as well. As long as your TV supports both formats it will play either.
