Good evening. for all of you who are wondering what type of media to use for your PS2 backups (of original games you own, of course), There are conflicting posts all over. Some say -R, some say +R. In my personal experience, every +R game i have backed up has worked flawlessly with my Swap Magic v3.3 discs. every -R disc has given me the 'Please insert Original PS2 Disc' error. I am using a new Slimline PS2 (SCPH-700XX). So, if you're new to backing up PS2 discs, and not sure what media to use, pick up a 3-pack of each and try for yourself, but my bet is that the +R's will work, and the -R's won't.
