today was productive. i got a super game boy, and i cleaned all my snes games, so they all work now. hooray for rubbing alcohol and q-tips
the nes is proving more troublesome. the problem there seems to be with the 72-pin connector as much as it is with the cartridges, and i'm having trouble cleaning the connector effectively even with the top cover off
i'll watch some videos tomorrow and see if i can make any progress. in the meantime i have cleaning kits in the mail for my consoles and carts
