Unfortunately this has nothing to do with the actual game, but the cartridge that it resides in.
Luckily for me I still have all my Atari, NES, Gameboy, SNES and Genesis games plus boxes in good condition. Though my gameboy ended up with dead pixels on the left and right borders. I went to checkout how much to replace it and it was around the 300 range...
Got to love 80's game collectibles.
