The 3DS eShop is shutting down, and it is okay.. | hSHOP 3DS Homebrew

As of March 27, 2023, it will no longer be possible to make purchases in Nintendo eShop for the Wii U system and the Nintendo 3DS family of systems. It will also no longer be possible to download free content, including game demos. Using hShop via 3DS CFW is looking like the best option moving forward.

As this date draws closer, related services will cease to function:

As of May 23, 2022, it is no longer possible to use a credit card to add funds to an account in Nintendo eShop on Wii U or the Nintendo 3DS family of systems.
As of August 29, 2022, it is no longer possible to use a Nintendo eShop Card to add funds to an account in Nintendo eShop on Wii U or the Nintendo 3DS family of systems. However, it will still be possible to redeem download codes until March 27, 2023.
Users who link their Nintendo Network ID wallet (used with Wii U and the Nintendo 3DS family of systems) with their Nintendo Account wallet (used with the Nintendo Switch family of systems) can use the shared balance to purchase content on any of these systems until March 27, 2023. After that, the balance can only be used to purchase content for the Nintendo Switch family of systems.

No changes are planned for Nintendo eShop on the Nintendo Switch family of systems.

The changes to Nintendo eShop on Wii U and the Nintendo 3DS family of systems will simultaneously take effect in software on these platforms where it is possible to make purchases, such as StreetPass Mii Plaza, Theme Shop and Nintendo Badge Arcade.

Even after March 27, 2023, and for the foreseeable future, it will still be possible to redownload games and DLC, receive software updates and enjoy online play on Wii U and the Nintendo 3DS family of systems.

From hShop Site:

What exactly is hShop even?
As you may already have seen or heard, we are a 3DS content preservation service. We provide preserved official 3DS content of all types along with a couple of extras. Our goal is to let the 3DS content library live as long as it possibly can.

Why was it created?
Preservation. A decent chunk of the official content we provide is no longer available for purchase anywhere. We want to provide most if not all content that is (or was) available for the 3DS. This is why we are also a preservation service, and not just one of those sites that provide CIAs.
