Power base converter This i think was one of sega's most advanced hardware, the sage power base converter. i am one of the lucky and happy owners of this hardware. I must admit it rocks. her are its stats and features enable you to be able to play SMS games and sms cards (yes damnit sms cards) on a gesesis 1 only works on genesis 1, wont fit on other models. rarity = its not to bad to find on ebay but impossible in places like funcoland. price = you may endup paying around $10 to $25 dollars for it on ebay if your lucky $5 plays all SMS games or atleast most of them. Pause button located on the system. If you stumble accross one and already own some sms game or plan to get some then you should get it if its a reasonable price if its over $25 forget it . its a rip off.
