I have a 7 year old grandson, who does not take care of his ps2 games at home. I have spent $100's of dollars on games. I would like to start making backups for him to play and keep the originals for when the backups won't work any longer. I just bought him a new console which I believe is version 15a. Can someone assist me with deciding which chip I need? I don't think the swap magic will work as he just turned 7. Thanks in advance for your help.
