Cloudpoint allows you to sync all of your saves (and extdata) between all of your 3DS & 2DS devices, via a central server. Transfer progress between consoles effortlessly, the way you're probably used to from more modern systems. Or PS Vita.

Features

Sync your game saves (and extdata) between all of your consoles (and, in most cases, emulators)
Simple UI with minimal user intervention (works like cloud save on any other console)
Public, free to use cloud available for zero setup syncing over the internet
Self hosting your own instance is also supported, via the provided Docker image
Auto sync all saves in one go, or sync specific game saves on demand
Enable/disable specific saves from auto sync
Auto discover your saves, and refresh them on demand as you add new games
"Link" your consoles to enable initial setup using local ad-hoc wireless; syncs all happen directly with the server (your consoles don't all need to be online at once)
Auto enable wireless on boot, disable on quit - be kind to your battery life
Slightly increased performance on New... model consoles (but works on all of them really well)

Installation

Cloudpoint is available on Universal Updater, which is the best way to install it and keep it up to date.

Or, download the latest release manually:

3DSX - Copy .3dsx to /3ds/cloudpoint/ on your SD card, then launch via the Homebrew Launcher.
CIA - Copy .cia to your SD card and install it via FBI.

User guide

If you have one console

Run Cloudpoint on your first console (console 1) - it will scan for saves and enable them for auto sync.
Press A to sync and wait for the progress bar to complete.
You are synced! Take your user key to a new console or run Cloudpoint again after formatting your system to restore saves and extdata.

If you have additional consoles

On console 1, press R to reach the "Link screen and press X to share your user key.
Run Cloudpoint on another console (console 2) - it will scan for saves and enable them for auto sync.
Press R to reach the Link screen and press Y to receive your key from the first console. Follow the onscreen prompts on both consoles; Cloudpoint will restart on completion.
Once Cloudpoint reloads, press A to sync and expect to be asked to resolve conflicts for any game You have installed on both consoles. You will usually see this screen the first time you sync a game on a given console, or if you progress in a game on multiple consoles without syncing.
You are synced! You are now free to use a N3DSXL at home and a N3DS on the go; no more compromise!

Best practice

Keep save backups yourself. Do this from time to time. Bugs happen and I don't want you to lose your 1000 hour Pokémon saves.
Make a backup of your user.key from /3ds/Cloudpoint/user.key (you will need this in the event you lose your console or memory card, there is no other way to recover your saves).
Auto sync when you pick up your console for a play session, auto sync again when you finish. This will avoid any need to resolve conflicts.
Use the same version of a game on all your consoles. Syncing saves to different versions may lead to data loss, so avoid this.
Take extra care when reinstalling titles or formatting a console; detection of title reinstallation should now work well (on real hardware at least; emulator support here is patchy), but it is the thing most likely to lead to unexpected behaviour, so please ensure you have backups before doing either of those things.

Screenshots

Limitations

Cloudpoint can't run in the background, and it can't automatically run when you launch a game. This isn't something which 3DS can natively support, so you will need to manually run syncs (see best practice).

3DS doesn't provide a method for knowing when a save was last modified, so we can't show that in the UI. We do know when you last synced a save, so we use that in the UI instead.
