Never even new this Nintendo add-on existed!

I knew most of this, but was surprised to find out that Metroid and Zelda first appeared on the disk system and were only later converted back to cartridges for the western audience.

Also, I wish I could have been there at the peak of the Disk System when you could walk into a store and load any game onto your disk like that. There's just something really cool about that feature.
