Warning
This mod is unmaintained. Old forge is extremely unpleasant to work with, and I really don't have the motivation to touch it, even with a 10ft pole. Contributions are still welcome, if you want to try fixing some of the currently open issues.
OldInput is a very simple mod that ports raw mouse input back to old minecraft versions!
It is heavily inspired by the Raw Input mod, big thanks to xCuri0 for the base mod.
