Help with the PS2 mod chip :Duo 2

[The_It]

OK, so I got a used PS2 at a garage sale and found out that it has a mod chip in it. I took it apart to see what it was and it says "Duo 2" on it. I was told to hold the reset button down for four seconds to start up a game, and that works for the official games, so I decided to make a copy of one of my games to see if it works, and I get that red screen that tells me to put in a playstation or playstation 2 disc. So the official game works, and its clone does not, but they are both supposed to work.

I have looked all over the internet for instructions on how to work this Duo 2 modchip, but everything is very unorganized and the forums just have useless information and unanswered questions. Is there anywhere that can tell me EVERYTHING about the operation of this mod chip? A place that is not vague in their explanation of how it works? If someone could post me a link, I would greatly appreciate it.

anybody got an idea? Do I need to use silver dvds or something? Or Memorex brand dvds?
