I want to wipe the cards playing memory and use is again for another game is this possile and how??

another game? SP1 card? i guess you mean a SOny Playstation 1 card, a PS1 memory card can hold 15 slots right? with an average game using 1-3 blocks up of the 15 spaces, from this you should be able to get atleast 5 games on, on the PS3 you can create in game memory cards for the PS1 and PS2 and use storage space to create this on your PS3, you can create as many as you want, but from the main screen page of the PS3, all you have to do is go to the Game section, then Memory card utility, from here you can create a new memory card, or view the ones you already have, simply selecting the memory card then pressing traingle to bring the options up will allow you to copy or delete them, which i presume is what you are wanting to do??

If you create a 2nd PS1 memory card, and use this as your number 1 slot when inserting a PS1 game, no data will be on the card, only on your other, so from this it will seem you have just bought the game and have no data of it

Strange forum to post this in i must say, but hope it helps
