Good overall condition. Normal marks from use.
For those who dont know Gyromite has 2 chipsets inside of it. The first one is the game board and the second one is an adapter so that it can be played in North American systems. The game board is a Famicom design and needed a convertor to work on NTSC NES systems. This cart has that chipset inside. If you take it apart you can remove the converting board on the bottom and use it to play Famicom games on your North American NES System!
