This device is similar to the game kiosks in game stores in Japan which allowed you to buy a diskette and insert money into the device and it would copy a game onto your diskette, for use in the Famciom Disk System. Except, this uses flash RAM carts and works with the Super Famicom. This is apparently a new development for the SFC, I had never heard of it before. More games are planned for exclusive release in this format. I guess the SFC still has some life left in it after all, too bad I can't say the same for the US SNES, however. Below is some information about this nifty device.

Licenced to Copy - By Nintendo
Available only in Japan, Nintendo actually makes a game copier of its own. It's called 'Nintendo Power'. Sharing the same name as Nintendo's magazine, Nintendo Power (NP for short) allows you to copy a game from this machine and play it into your SNES console, at a significantly lower cost.
It works something like this: First you buy a SFC cart named 'SF Memory Cassette', which contains 32Mbit flash memory and 256kbit SRAM for 3980 yen. Then you go to a shop with a NP machine, insert the cart, and choose the title(s) you want from the machine. If your cart is already full, you will need to delete some space. After you have downloaded the games, you go to the counter and pay for the titles, and receives the manual(s) for the respective game(s) within 3 minutes.
The titles for NP costs 1000 yen (old) to 3000 yen (new ones, especially the ones sold exclusively for NP) per title, which is much cheaper than they were originally released. There are, however, some titles are missing from the NP releases. All the titles that require special chips like DSP, Super FX, etc. are not available as part of NP inventory.
Note: 2 Mbit titles (eg Space Invader) automatically rounded up to use 1 block of flash memory each. Similarly, 10 Mbit title (eg Final Fight 2) uses 3 blocks of flash memory.
