This is quite the funny story about this game... Its called Big Nose the Caveman..
I had never seen or heard of the game before. My dad works at a bodyshop and there was a car that had been smashed in and sitting behind the shop for several years. When they decided to have it hauled off to be crushed my dad went out to look at it when he noticed the trunk compartment was nothing but large pool of water with a nintendo cartridge floating in it. He picked it up, brought it inside, and brought it home.. It worked in my nintendo and still does about 80% of the time.
If I weren't too lazy id get out of bed and post a pic of it
