Your Options Shall Be Saved (YOSBS) is a lightweight utility mod that lets modpack creators define default configuration files without overwriting player preferences
Updating a modpack often resets custom settings like keybinds or mod configs, because most launchers replace the entire config/ folder
YOSBS solves this by copying any file placed in config/yosbs/ to its proper location only once on first launch — and never again
This gives full control to the pack author:
- Files inside
config/yosbs/are treated as user-owned: copied once, then left untouched - Files inside
config/behave as usual: they will be replaced on each update
That way, you decide which configs should persist, and which should reset
Features
- Zero-config: just drop the defaults under
/config/yosbs/…(or legacy/config/yosbr) - Works for any file –
options.txt, mod configs,optionsshaders.txt, etc - Runs in the pre-launch phase, before Fabric/Forge starts loading the rest of the mods
Compatibility & Installation
- Fabric Loader ≥ 0.4.0 (No Fabric API required)
- Minecraft 1.14 – 1.21.x
- Requires Java 8 or newer
- Put the YOSBS jar in
mods/and launch once – the folder/config/yosbsis created automatically (or create it manually)
Usage examples

|---|---|
A default options.txt |
