Convert old blend model to cycles

I have an old file for some charcoal in blender
and it is a mix of proc map and a ramp emission

is there a way to redo same mat in cycles ?

may be using a ramp function of Z !

did test with principal shader and color mix but red emission is too low !

thanks

I’d try Charcoal material setup.
Emission material setup.
Add Shader to add them together.

can you show nodes set up
