Install options in RatOs 2.1.0 RC2 - no V-Core 4

Hi, I'm configuring RatOs for my new V-Core 4 500 build, and this machine is not listed as supported. Is there a link to a template for the neccessary printer.cfg file? I chose the V-core 3 given a lack of options, but noticed that the y-stop is in a different position on the Core 4, and i'm probably going down the wrong path.

I read the documentation, but the Core 4 is not listed as a supported device

What the heck am i supposed to do here?

Thanks!
