[quote name='detectiveconan16']I don't think you could find any sealed 1st party cards, unless you get lucky on eBay. If only there was someway to back up PS1 saves from my cards to my computer w/o a Dexdrive or those legacy ports... I actually worry about my saves being corrupted...[/quote]
if your using a ps2 you can transpher your saves to a ps2 card. You can't read them off of the card, but you can store them there and access them later. I have a 64 mb ps2 memory card and a 32 mb one, so I usually back up my saves that way.
And as far as 3rd party ps1 memory cards are concerned, you can't use them on slimline ps2's. Learned that the hard way. Needs to be first party for it to work on a slimline.
