Hmm, Isnt those orginal games dvd-rams? Are those much more expencive than normal dvd:s? Havn't checked yet.
These dvd+r works nicely, have to try with dvd-r and orginal games and compare sounds. What i know is that scratches on cd:s,dvd:s damage or at least stress laser.
As long as it runs nicely (without strange sounds) it should be ok. I remember my friend had ps1 with mod-module probably more than 3 years and we played scratched dirty cd:s and even fixed that spinner holder with "bluevax" XD. It worked perfectly, well old ps1 lasers are kind of better than new ones but of course they are not dvd readers.
