Some players are reporting that DSiWare games are beginning to disappear from the Nintendo 3DS eShop. This is a bit sudden, as Nintendo nor any company that has released games onto the platform has made any sort of statement on the matter. Some users have speculated that this may actually be an error and that the games will be relisted once Nintendo notices the mistake. If this is an intentional decision, then anyone who has managed to download these DSi titles now has a digital collector's item!
Looks like on Jan 1st Nintendo of America pulled the plug on DSi titles on the 3DS eShop that were 10 years old. 2010 releases and older are gone. My checks show most titles still available in EU but not sure about AU, CA, JP, etc https://t.co/REOeRyK42K— Delisted Games (@DelistedGames) January 4, 2021
