About this Mod
Yomi's Joban Client Mod
This mod is a compatible and enhanced fork of the original Joban Client Mod (JCM).
It is specifically designed to work with YMTR (Unofficial MTR fork).
Why This Fork Exists
The original JCM relies on specific internal APIs of the official MTR mod.
YMTR (my fork of MTR) modifies some of those APIs, making the original JCM incompatible.
YJCM is a necessary adaptation – it allows YMTR users to continue using JCM-like features without losing functionality.
Significant Differences from Original JCM
Full compatibility with YMTR – The original JCM does NOT work with YMTR. This fork bridges that gap.
Sound Looper now supports web audio streaming (
.wavformat only)Compatibility with YMTR’s creative mode inventory tabs

Precautions for Web Audio Streaming
- Audio must be in WAV format (OGG/MP3 cannot be played)
- Ensure the URL is safe
- Do not stream network audio too frequently to avoid stuttering
