About this Mod

Your Options Shall Be Saved (YOSBS)

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/yosbs is created automatically (or create it manually)

Usage examples

Want to ship…	Do this before first launch
A default `options.txt`	Place your file at `/config/yosbs/options.txt`
A REI config	`/config/yosbs/config/roughlyenoughitems/config.json5`
