Yup yup, you can move them to a PS2 memory card, but you can't load the save directly from there. You'll have to move it back to a PS1 memory card (or an internal PS1 memory card on PS3) to actually be able to use it. Before the PS3 entered the picture it was a great place to storage PS1 saves. :] My silly PS1 memory card only has 16 kb, or something.
