you need a ps1 memory card
No they can not. Although you CAN play PS1 games in a PS2, you'll need a PS1 memory card to save them.
yes, as long as its a playstation 1 memory card you are saving to.
Yes, but you cannot save playstation 1 games on a playstation 2 memory card as they are not compatible.
The PlayStation 3 has 256 MB of XDR main memory and 256 MB of GDDR3 video memory.
The PlayStation 3 has a built in Hard Drive. Ps3 game saves will be saved to the Hard Drive. But to save PlayStation 1 + 2 games, an internal mermory card must be created inside the Hard Drive. PS1 + PS2 games will save there. So no you don't need a memory card for the PlayStation 3.
No. You just won't be able to save the games. You build the memory cards in the HDD for the 4 USB port models that play PS2 games and many games need to do this
Yes
Yes the Playstation 2 unit will play all the original Playstation games no special equipment is needed except an original Playstation memory card if you desire to save your game progress.
Nope, you'll need a PS1 memory card.
No, one cannot save a PlayStation game without the use of a Memory Card. The original PlayStation lacks internal storage and relies on Memory Cards to create game saves. The same applies to the PlayStation 2, although the 40GB HDD accessory allows the creation of game saves on the internal hard drive. With the release of the PlayStation 3, game saves are created on the internal hard drive, negating the requirement for a separate memory card.
