Leo_A, I wouldn't count on being able to re-download anything that has been de-listed by Nintendo. Zelda: Four Swords was supposed to be available for free and only for the 25th anniversary of the Zelda series. It is now de-listed on 3DS eShop and DSiWare. From what my research indicates, you cannot download or re-download it at this time or in the future whether you have downloaded it in the past or not.
