Ok, here is my problem. My Ps2 is acting odd these few month, because it can no longer read any PS2 games I burn. Ps burn games are working just fine. I have my Ps2 for like 4+yrs. My Ps2 is the fat type, but which version I am unsure. I do have a modchip, but it was already implanted in when I bought it, so I don't know what type it is. I was told that to use it I need to hit eject button and then hit reset to use the modchip, maybe that can help. I am using Sony DVD-R right now to burn games, and so far none is working. I used to use TDK DVD+R for burning and those work for a good 3 years or so. I have to make new copy every so often though, because they stop working or turn choppy after a month. Slowly my Ps2 can't read my burn PS2 game, so I tried buying Sony's DVD-R, but the difference it makes are nothing so far. So my Ps2 can't read any of my Ps2 back up now. However, any of my Ps game last very long and work 100%. As for what I use for burning, I tried Alcohol 120%, Nero,DVD Decrypter. I only use Alcohol for the first working three years, after my PS2 games stop working, I tried the rest to see if it help and no it doesn't. I always burn at the lowest speed,1x. I tried to fix the problem many ways, including opening the Ps2 to clean and adjusting the light, but nothing works. I had a friend who bought games from Hong Kong, which are illegal copies, and I borrowed a copy game from him to test on my Ps2. To my suprise, it works very nice, while I switch back to my own back up Ps2 games, they are unreadable.So far, I only have problem starting the game up, where the Ps2 Logo coming on before the game starts. Usually after that part, my games always work perfectly. I also tried buring my friend's Ps2 game and see if it works on my Ps2, but it get the same result as my other burn Ps2 games. Sorry for typing so much, but please help me out here, this odd problem has been bothering me for a while now. Thanks for taking the time to read this problem of mine.
