I recently picked up a copy of Hudson's Same Game ... however, it's a pretty strange cartridge. I looks a lot like a Super Gameboy, but with a pin connector inside instead of a slot connector. (A picture of the cart can be seen at: http://www.asahi-net.or.jp/~uw7g-bwr...e/samegame.htm )
The manual shows the cart being used with the BS-X system.

I was wondering if anyone knows anything more about this strange cartridge. Are there more mini-carts for it? Is the mini a ram-cart or something? What was the BS-X used for with it? Anything else known about it would be helpful.
