Can you clarify in your readme any licensing terms for usage/derivatives of the SNES portions of this repository?

I am utilizing SNESGSS as the primary audio system for a project I am working on, and I am making zero modifications to the tool itself.

However I have re-implemented the SNES integration to better fit within the usage of my game and it's engine. As I based this on your sample code here, I want to clarify what, if any, licensing terms I would be bound by. If possible, could you add licensing terms to your readme or add a separate license file to this repo please?
