Well, this is definitely something. The Super A'Can was released in the 1990s in Taiwan by the company Funtech. It is supposed to have similar capabilities to the Super Nintendo. The cartridges do look similar to the Super Famicom.
I don't know much about it, as the games and instructions are in Chinese. At this time, the one game that I have is some sort of RPG/board game. There are many menus, so it will take alot of work to understand.
