At around game 150 or so in my collection I finally got one that doesn't work. No amount of cleaning, taking apart, etc., could fix it. The game was Dragon Spirit for NES. Not being a huge fan of overhead shooters I'd guess I'm not missing much, but it's still $4 lost. Anyone else ever get anything only to find out it doesn't work when you get it home? At what point in your collection did it happen?
