Intermediary (mod tool)

Intermediary was a mod tool developed by FyberOptic that bridged the gap between 1.2.5 and 1.7.10, allowing for mods to be playable from 1.2.5 Forge & Risugami's Modloader in 1.7.10 Forge environment.

A list of 15 mods had been properly tested, but some load with success or result in crashes. Only specific versions of these 1.2.5 mods work with Intermediary however, so any file that was a version above or below do not work. 1.2.5 and 1.7.10 mods may work together but to mixed results, so it is recommended to use the 1.2.5 mods with Intermediary in 1.7.10 instead of using both versions mods together.

The available mod list and additional information about Intermediary can be found here via the Original Source
