Okay, so I have a modchipped PS2. I bought it off eBay. It worked fine with me for burned games for 8 months. Then, while I was playing Death By Degrees, the game went to the PS2 main menu for no reason and then my PS2 fan went really loud. I got scared and had to pull the plug off the PS2. Now, when I plugged it back and tried to play the game again, it went to the PS2 Browser screen! Literally, most of my burned games wouldn't work with the PS2 no matter how much I tried BUT there were only a few burned games that could read fine on my PS2 (Samurai Champloo, FFXII). So now my PS2 can read all the original games and very few burned games, but I think it's a laser problem. I don't know what kind of laser I have, but my friend has a 400b laser that he can replace for my PS2. Would that laser work? EDIT: Or, should I clean the laser? Which is better?
