I’m sorry, but I don’t have information on a game titled ‘Space Missile Space Fighting Game’ from 1980 developed by ‘bootleg’. It’s possible that it may be an obscure or less-known title. However, you could look into sources such as retro gaming forums or databases, as they might have records of rare or less-documented games. If you have specific aspects of the game you’re curious about, providing those might help narrow down relevant information.
