About this Mod

ForgeConfig mod is a modding library for mod developers that provides Forge's whole config system to other modding ecosystems. Allows developers to use Forge configs on LegacyFabric & FishModLoader.

This mod is similar to the Forge Config API Port, although it was developed without referencing the Forge Config API Port.

This mod is ported from Forge 9.11.1.1345.

This Mod was originally made for 1.6.4-MITE and BTWCE3.x, but it can also work without relying on these two mods.

This mod does not rely on Minecraft and can theoretically run on any Fabric/Legacy Fabric version. It can also run on the FishModLoader for 1.6.4-MITE. However, because Forge configs differs significantly across different MC versions, it is recommended to use this mod with MC1.6.4 whenever possible.
