About this Mod
Notice:
This is my first mod. Do Not Expect Much.
As of now, the mod features are made to replace similar features in Recode as it has been discontinued. I am willing to add non-Diamondfire related features to expand this mod's functionality. You can come suggest some in my Discord server, or contribute to the project through GitHub.
Setup:
[!] This mod uses .nbs files obtained from Noteblock World.
- Launch game with the mod.
- Place
.nbsfiles in NBS songs folder. (<Path to Profile>/NBSE/NBS Files/) - In Creative Mode, use

Planned Features
- Gui shows more data about each song file
- Config Menu

You Can Help:
- Clone the GitHub Repository.
- Make changes to help improve the mod.
- Create a Pull Request.
It has only been me and RedVortex working on this, but code suggestions can help further this mod. You can even add your own personal touches to existing parts. (e.g. UI adjustments.)
