Hey there, I have a customized version of the Model 01 firmware (see [here](https://github.com/jjochen/Model01-Firmware)).  
Now I wanted to reuse it for my new Atreus 🎉. But I’m not sure how to use the non Chrysalis firmware on the Atreus.

Any suggestions?

You are dealing with two very different keyboards containing different features that aren’t going to allow you to do this (lights, key layouts, etc.). I don’t think you have much choice but to cut and paste favorite parts of your code into the default firmware for the Atreus. And if you haven’t given Chrysalis a try yet, that might be faster for configurations. I had just a handful of firmware mods that Chrysalis won’t handle, like mouse movement acceleration changes.
