This is the "GB Interceptor," which can capture video from the Game Boy, Game Boy Color, and Game Boy Advance. I'm selling it because I no longer use it, although I've only used it a few times. Unfortunately, the manual is not included, so I apologize, but please check the internet for detailed instructions on how to use it. Available for immediate purchase, and price negotiations are not accepted. It will be shipped via Yu-Packet Post Mini. Please feel free to ask if you have any other questions!
