About this Mod
What is this?
This is an unofficial port of Shape Shifter Curse, migrated from Minecraft 1.20.1 to 1.21.1.
The original project is actively maintained for 1.20.1. This port is based on the latest available upstream source, independently maintained, and aims to follow future updates.
Project updates on Modrinth may be infrequent. For the absolute latest development builds, please check the GitHub Releases page.
> This project uses ClaudeCode + DeepSeek-v4-flash/pro for code modification and porting work.
Planned and ongoing development
| Loader | Latest Version | Status |
|---|---|---|
| Fabric | 1.9.2-dev.16 | Beta |
| NeoForge | 1.9.1-dev+build.8 | Beta |
| Forge | None | Not Planned |
Important Notes
This port is not compatible with the original 1.20.1 datapacks. The 1.21.1 datapack structure has major internal changes; using old datapacks directly will cause game startup failures.
Existing bugs from the original mod have not been fixed in this port, so stability may be limited.
If you encounter any issues, please report them via this port's GitHub Issues. Do not report problems from this unofficial port to the original project's issue tracker.
