I've been ripping PS3 games for a little while now. I've recently bought some Dynasty Warriors Gundam games from Japan which I'm dumping at the moment.
Armoured Core has especially been in a thorn in my side. I've got 4 and 5 but still trying to acquire For Answer and Verdict Day. They're extremely hard to come across. I haven't looked at the PS2 games but I'm sure I could find those for cheap. Super easy to rip with a standard Disk Drive.
