straight and simple,
This review is from: PlayStation 2 Memory Card (8MB) (Accessory)
If you want to save a PS2 game, you need this PS2 memory card -- PS1 memory cards won't work. If you are playing a PS1 game on your PS2, you must also have a PS1 memory card; PS1 games can't be saved to a PS2 memory card.
