i dont think you can as it doest seem like it is an app you can download moreso just a community of people who like to play virtual console games on 3ds

This is just a hub community for the myriad of Virtual Console games. People love the Virtual Console but there are too many games to make a community for each.

you can't get virtual console 3ds titles on wii u but you can with NES, SNES, N64, GBA, NDS, and Wii (According to the shop)
