I still have a PS2, because I've never felt the need to buy the next gen ones.
Anyway, I've always loved its backwards compatibility. The ability to play Worms on it has often delighted me.
I bought Resident Evil 1 last week, and imagine my fury when I got quite far in and realised I couldn't save the data to a PS2 memory card.
Do I need a PS1 memory card for this? I was under the impression they wouldn't be recognised in the PS2, but I can't think of any other way you can save your game.
This could be really awful if it's the case, as I was about to start buying some glorious old games like Metal Gear etc.
