Hey folks, I have a PS2 version SCPH-30001. I think it's a version 4 because it has the electrical hazard warning on the bottom of the case (serial US5 PREFIX) 1C date code. I am considering backing up some games but my unit doesn't seem to read my DVD-R movie backups. I am considering buying the slidecard and the smartdisk DVD mod. Will they work then? Will I have to copy to DVD-RAM? I used Memorex media and TDK as well. Neither worked. Any suggestions? Will I need a solder in Chip?
