I got my PNP No Solder mod chip with Swap Magic 3.3 today, but cannot get a backup to work to save my life! Everything seems to go good until I put the backup in and then it says that it is not a valid PS2 disk. I cannot get past this. I am on a Mac and am wondering if it is possible to make a backup using a Mac. I don't see why not, but I cannot figure out what is going on. I have burned the .iso image as an image.... nothing! I tried to use Toast and do a DVD to DVD copy.... nothing! Tried with many of my DVD games as well as my CD games and..... nothing! I even tried downloading the DVDLoader thing that I thought might help, but it does the same thing... tells me that it is not a valid PS2 disk. That is when I thought that maybe when you burn the image or copy the disk on a Mac it is doing something different that is screwing it up. I don't know.... Here is what I have: PnP Chip Swap Magic 3.3 disks Lacie (NEC 3500) CD/DVD Burner Sony DVD-R disks Burning at 2X speeds I have been searching forum after forum... It seems the main problem when this happens is because of bad media, but I am using Sony DVD's and from what I have read they are good for PS2 backups. Someone please help me!
