macrovision free with IC-cercuit ?

[sp4m]

Hi... for some while ago i read about a guy who hade made his PS2 macrovision-free with just a simple IC-cercuit?

Does any one know witch IC, and how to connect it to a V7 PAL ?

Alsow i've seen companys selling simple cercuits that makes the PS2 region code free, does anyone have any experience in this? Is this also a simple IC-cercuit, or is it programmed with any code?

If you have the V7 you can't just solder 2 points together to make the green-screen disappear, right?
