It appears Nintendo is pushing hard to sell the “NEW” 3ds systems with their most recent batch of eShop games
Pilotwings, Super Mario World and F-Zero will be available today but the SNES downloads are only for the NEW 3DS or NEW 3DSXL.
Meaning for some reason they won’t play on the 2ds or 3ds hardware.
In addition to those games Super Mario Kart, Earthbound, Super Metroid, Donkey Kong Country, Donkey Kong Country 2, and Legend of Zelda A Link to the past.
But why are these games only available for the “NEW” system? Many of these titles were playable on old hardware such as the GameBoy Advance.
More information is available in the Nintendo Direct video.
