Master System Power Base
I have several of these, but have lost track of them all. These system contain inbuilt game, although they vary. Some include Alex Kid in Miracle World, others Hang On.
Description
The original Sega Master System Power Base supports both cartridge and cards. Few games were sold on cards, however the 3D glasses also interfaced using the card slot.
These were quite popular and competed well against Nintendo in the local market, much more so than in Western Europe and North America.
