Usually when I am testing a new pickup lens or pot adjustments I use Gate of Thunder, Intro and playing the game. I then play an audio disc that covers most of the disc area.
If all goes well then I test the intro's to about 5 more games to make sure there isn't any skipping. I then play Dungeon Explorer 2 and get through a couple more animation screens within the game itself.
Once I get this far I am usually happy if I did not experience any issues.
It's not scientific but since I do not have an osciliscope (<- spelling) this is the best way for me to verify if there are issues.
