My four slot works well but sometimes it takes a little effort to get all four cartridges to be happy. I'll have to reinsert the carts many times before they all jive.
Is there a recommended way to clean the contacts on the slots? I thought about spraying some electrical contact cleaner in there. Good idea? Bad?
