As far as I know, my original not-slim PS2 still works... it's been about half a month or so since I played Disgaea 1, LoD or FF6 on it, and the only one that had trouble was LoD in some spots (granted it's the oldest of the 3, and I've played it the most so Disk 3 is pretty brutally scratched up) so yeah, still works like a charm.
