I exclusively use Taiyo Yuden CD-Rs (gotta stock up, manufacturing has stopped. Hopefully being in 95F heat for a few hours a day during the summer won't damage them) and an older Plextor burner from 2003. Together I can burn discs that even the pickiest PS1 has no trouble reading. It's shocking just what the right pairing will do. You go from consistent garbage to 100% readable burns.
