I have Contra&monsters inc. gameboy carts. they look different from all the other carts I have.
The CONTRA cart is standard size, it only says GAME across the top in the mold. Not nintendo game boy, etc...And there is a philips Screw in the back of the card holding it together...
the MONSTERS INC is standard ize, It also only says GAME across the top in the mold. Not nintendo game boy, etc..And there is some sort of recatangular japanese sticker covering the screw hole on the back of the cart.
they both look like normal Nintendo gameboy games, except for the word GAME just writeen in the grey cart mold.
Any info would help. The might be normal releases I just dont really know.
SORRY IF I POSTED THIS IN THE WRONG SPOT IM A NEWB.
