I have a PS2 and my family plays both PS1 and PS2 games on it. I use both PS1 and PS2 memory cards. I have no problem saving/loading games from these cards. My problem is that some games appear to be slot specific. For instance, I can only access the PS1 memory card for "Harry Potter" (PS1 game) if the PS1 memory card is in slot one. However, "Spyro" (also a PS1 game) can access the memory card regardless of what slot it is in. I find the same problem with some of the PS2 games (Madden 2002/Splashdown) we play.. Some will only access certin memory cards slots. Is there a way to set the PS2 system or the games up so it knows which slot (1 or 2) the necessary memory card is in? It get's tiring having to switch the cards from slot 1 to 2 all the time. I usually keep my PS2 memory card in slot 1 and my PS1 memory card in slot 2.
