JustDanceNextPlus

Just Dance Next Plus is a custom Just Dance server that allows you to play both official and custom Just Dance maps.

Currently, the server is still undergoing development and is not yet ready for public use. However, I have made the source code available for anyone who is interested in contributing to the project.

⚠️ WARNING: USE AT YOUR OWN RISK! ⚠️

By choosing to use this tool, you accept that there are NO guarantees your save data will remain intact.
With every update, you risk permanently losing ALL stored data.
Proceed only if you're prepared for this possibility!

Features

• Play official Just Dance maps
• Play custom Just Dance maps
• Save your scores and view leaderboards for maps that have scores submitted from at least 1 other player (quirk of the game)

Installation

1. Clone the repository
2. Place the json files under database/config/ (you will need to dump these yourself for legal reasons, I will not provide them nor will I tell you how to get them)
3. Add maps under the wwwroot/maps/ folder
4. Run the server
5. Run a proxy or custom dns server to redirect your game to the server (you will need to disable ssl certification on the switch to do this, can be found here, 18.0.0 and above here
6. Enjoy!

Needed JSONs

• activity-page.json
• playlistdb.json

The following are not needed but are recommended:

• tagdb.json
• localizedstrings.json (from the All.US-en.*.json.gz file)

Bundles

Feel free to modify the bundles to your liking, but make sure to keep the same structure as the original bundles.
