Hello!, I was looking at some of my Gameboy cart's PCB'S and I discovered a strange difference with my Tetris cart. I put the other carts near it for comparison, but it looks like the Tetris cart is a bootleg by its PCB design, even though the cart has Nintendo's security screw and what seems like official casing. Does anyone know why Nintendo would use a glob of epoxy and cover the die unlike any of their other carts, or do I have a Tetris bootleg?
