PS2 game is unreadable for some strange reason?
Ok, I just bought Rock Band Special Edition, and I everything. For some strange reason, the disc was the only thing that did not work and finally I tried a lot of things to try to fix it. It has a silver back, and my PS2 continues to play behind silver. The PS2 game is also read by the computer (not playable, though), but not for my playstation. What is this?
I've had my ps2 for about 8 years. from time to time when I try to play Madden NFL, say disc unreadable, but when I try to play NBA 2k7, it works. The next day I tried to go crazy and it worked. so sometimes, certain games work at different times. just trying to play the game again later and see if it works.
