I like the experiment, but I'm curious to hear how you reached this conclusion. Increasing the conductivity and, therefore, rendering the game playable seems pretty far-fetched; the magic, I would argue, is simply reseating the game (which one has to do after blowing on the cartridge each time).

Sounds like a second science experiment that could be done...
