Gaming Historica | Double Dragon Prototype YHJ Sale (Patreon)

Last year a Double Dragon II prototype cartridge (Japan Famicom version) sold on Yahoo Japan Auction for ¥151,000 /$1000 USD!

It is use the plastic case of a Famicom Disk System adapter. The start screen show “Sample Version”. This will have come from inside Technos offices. In Japan people do not easy to put the rare versions they buy on the internet.. but maybe one day.

Nobody know if this sample version is different from the final versions. Maybe!
