About this Mod

It allows players to use simple JSON syntax to change or overwrite hard coded text in other mods that helping translators with translation.

And you don't need to worry about run time or performance loss. This mod uses ASM for efficient class replacement, and caching only be updated the replaced classes after the target mod is updated, so its impact on modern computers is not significant.

Version 1.4.2+, supports bytecode modification of mod code.
