i've been pulling a lot of my old ps2 games out of storage recently and i noticed a lot of them have the same wierd marks on them - near the out edge of the disc (in one small section only, near the top of the disc) it looks like someone spilled some juice on them. so i try to wipe it off and nope! it won't come off. wet some cloth and try again and nope! still won't come off. damn near every disc i've checked has had this same problem. i stored all the discs on their side in some big plastic bins and they've been sitting in those for 3 or 4 years.
i haven't dug out the ol ps2 to actually test them out yet but i'm already shitting myself with worry. i want to sellf these off but if theyre all fucked then i'm out a ton of money. anyone every hear anything about this? help would be greatly appreciated?
