Master System II

In 1990 Sega regained the U.S. rights to the Master System which they had sold early in the console's life to toy manufacturer Tonka. In an attempt to improve sales a smaller version of the Master System was launched. To cut production costs Sega removed the card slot which meant users could not play Sega Card games or use the 3D glasses. Also removed was the A/V output and the reset button, along with the Expansion port.

Despite the Master System II now being marketed by Sega, it was too late for the machine in America and the public simply weren't interested. As a result of poor sales, Sega decided to withdraw the Master System II from the American market in 1992. Support for the console continued in Europe until 1996, where it was eventually dropped to allow Sega to concentrate on the Mega Drive's successor, the Saturn.

Hi. I am currently going through my SMS games and detailing in a spreadsheet which I own (and which remain).

I''ve come across something that has confused me - Captain Silver but with NO barcode on the back of the case.

Have you ever heard of this? The items I see on Ebay all have barcodes, where my case instead has an empty space (just the squares of the standard SMS game box).

The game appears legit, and works on my PAL SMS.

What do you think?

Never liked the controller for the Master System. The D-pad felt way too imprecise and mushy for my liking, and the buttons just didn''t feel good when you pressed down on them. Thankfully, you can use a regular Genesis controller instead.
