Minecraft Beta 1.7.3 spoilerDownload, Mirror buttons. (Do not use Download 1, Download 2, those are very likely to be dead for all editions)During the first launch, OptiBabric will find and transform the OptiFine zip to be compatible with Fabric.
This transformed version can be found at .minecraft/.optifabric/optifine-remapped.jar, but in most cases you don't need to touch it.
OptiBabric will detect if OptiFine was replaced with another edition and will rerun the procedure automatically.
