"Aurora GSI for Minecraft is a client-side only Forge [and Fabric] mod that sends game variables from Minecraft to the Aurora keyboard lighting software. Aurora can then use these variables to change the lighting on individual keys on your RGB keyboard, such as making a health bar or experience bar. The official Aurora GitHub page, which contains a list of compatible devices, is here. Make sure to download Aurora, this mod achieves nothing without it.
Aurora is an open-source unified keyboard and mouse lighting software that supports many different brands of keyboards including Logitech, Roccat, Razer, Corsair and more. It is highly customisable and provides an unprecedented level of control." - Aurora GSI original CurseForge post.
Aurora GSI Continued is an up to date fork of Aurora GSI (currently) under active maintenance. I hope to keep it up to date for as long as I can/want to.
All the credit for the original mod goes to the original owners.
