Neither game was sealed new. Both were in VG condition. I have no knowledge of their prior history, but this is just, as I stated a basic test ... we're not going to get into any other specifications other than clean and in good condition at the start of the test.
Both of the games were tested on a Yobo NES clone prior to the start of the experiment, both passed booting up, and both were cleaned with circuit board friendly freon to remove what little oxidation there was.
I'm not sticking "Subject B" into any of my systems once it has been blown into for 30 days straight ... so if you really want to see if it "works" at the end of the test, I'll do my best to get some access to a toaster NES and we'll see if either work, HOWEVER this really is more about the external visible oxidation/corrosion damage than anything.
I just want to SEE what kind of VISIBLE exterior metal damage blowing into games creates.
