I'm glad they never released the Famicom Disk System in North America and instead retrofited those games in cartdrige format for our market. I was a kid and while my parents bought me a NES they would never have agreed to buy the FDS. They are probably not alone. Also, to a north-american eye, the Famicom was ugly as sin, looks like a Fisher Price piece of crap. Can't put that under the living room's tv set and most of the homes in the '80s had exactly one tv. A redesign was mandatory. The loading mechanism was an error but we know that only in hindsight.
