This Reddit postmade me look into this rabbit hole again.
I should be no big deal to change the Razer RGB implementation of Factorio to work with other brands. Since there are a few good programers here maybe we can even do it ourselfes!
The best shot is the Aurora project. A open source programs which allows the different RGB SDKs (Logitech, Razer, Corsair, SteelSeries) to work which each others. It even has a build in wrapper for Razer supported games, but it doesn't work if I apply it for some reason. Other users have the same problem.
Edit: Correction, it kinda works.
Of I install the wrapper patch I get the flashing of keys. But just the key flashing in red, the rest of the keyboard does nothing, it doesn't even show a background color.
Support for non Razer RBG hardware - Aurora
Re: Support for non Razer RBG hardware - Aurora
i suppose adding aurora support directly into factorio itself would be benefitial to us.
