So I perchaced Guilty Gear X today (I already own XX but I wanted it anyway) and I come home open it up and notice the disk is blue like the Ps1 games. I thought it made sence because it was such an early release. But then I pop it into my Ps2 and it's all like DISK READ ERROR WHORE. So I'm like >< then I go and clean it and stuff but that didn't work either and then I put XX in, and it worked fine. So I'm wondering what the problem is. The disk is not scratched, smuged, or anything btw.
