I have a V4 PS2 with the messiah 2 modchip installed. I wanted to know if it is normal to have to reset the PS2 up to 10 times to get a game to work. Sometimes the games will boot first go and others will take ages. I don't know much about the internals of the PS2 but if it is the laser is it easier to get a replacement laser to fix this problem. If I do get a replacement laser does it matter which kind, or are all the lasers the same no matter which vers PS2 you have.
