I have been using Memorex black cd-rs for all of my backup ps1 games and have been burning @ 8x's with alcohol 120%. They are not working for some reason in my modded ps2, yet ps2 backups work flawlessly. Every now and then they will work, but that is like 1 out of 20 tries. However, the backup ps1 games do work on my emulator for dreamcast and PC? What could be the problem here? Could it have to do with my mod chip or maybe my burn speed?
