My ps2 can't boot dvd9 games directly,instead i need to boot it via gameshark/action replay. I have a pirated copy of MGS2:substance,i'm not sure if that game is pressed or burned since i bought it,but it is not the original copy afaik. i boot it with an action replay disc,and the whole game runs without any problems. My ps2 has a modchip installed,but not sure what model it is. If i'm not wrong,i think it is messiah. I could run burned dvd5+r games flawlessly. So,will a burned dvd+r DL boot up in my ps2? Provided i have patched the image with toxic's dual layer patch?
