I am selling Genipak - video game enhancer for Sega Mega Drive by Realtec.
The box is in pretty good shape, I have the codebook and the cartridge is still sealed - never been used. Paypal is accepted and I can post worldwide. There is a detailed listing on ebay - go there for more info or PM me. I know this is quite rare and there is not much information on the web. I hope someone will apreciate the quality of this find and it will get in to good hands.
