I have a ps2 since past 8 months. It was a modded unit. I have only played pirated games on it since they're so cheap (Rs. 25 in alfa, mumbai). Mostly the games run fine and don't give any trouble. But sometimes they don't work properly. E.g. I have 2 God of War discs, both pirated. Both run fine initially. But after reaching a particular point in game story (when Kratos reaches Pandora's temple) both discs stop working. The discs have been bought from separate shops. Still the problem. Similar problem was caused on my Resident Evil 4 and Metal Gear Solid:Subsistence discs. I had no option but to buy a new one. And shop keepers don't give guarantee or replace pirated discs. But still, their low price makes you overlook all these problems.
