Swapnote also known as Nintendo Letter Box in Europe is a Miscellaneous game that was developed and published by Nintendo for the Nintendo 3DS and was released on December 21, 2011. Create handwritten 3D notes and send them to your friends! Add stationery, photos, sound recordings, and more! Swapnote lets you create handwritten notes and then share those notes with other Swapnote users on your friend list via the SpotPass and StreetPass features. Nintendo might even send notes to you too!
As your note collection grows and you spend Play Coins, you’ll unlock new features and be able to personalize messages even further by changing stationery patterns, attaching photos and sound recordings, writing and drawing in 3D, and more. You’ll even be able to surprise your friends with secret notes that they can only open on a certain date! Passing handwritten notes to your friends is a breeze, regardless of whether they’re sitting across the room…or across the world!
If you find a ROM that's encrypted, you need to use the Batch CIA 3DS Decryptor, created by Matif.
Not all games are fully compatible with Citra. If you do find a game that's not working, try using the latest PabloMK7 Citra fork, the continuation of Citra since its shutdown.
Citra is an open-source 3DS emulator for Windows, Mac, Linux and Android devices.
It is designed to recreate the functionality of the Nintendo 3DS system on other platforms, enabling users to play 3DS games in higher resolutions and with improved graphics.
