Stadium Events? Yup. This game was pulled from store shelves, making it without a doubt, the hardest to find licensed, released, game available on the Nintendo Entertainment System.
For more info on the game, read this post I wrote several years ago. The game is worth around $2,000 or so and one just sold this past week privately through a forum with manual for $4,000.
