GBA/GBC/MGB link port
this link port is new/unused and is the style from the GBA, GBC, and MGB consoles. they have a bump along one edge exactly the same as the GBA link port, but will accept the cable plugs from a GBC and MGB console.
great for use in your projects and for building new devices! also for replacing those link ports in consoles which may have been damaged.
