GPIOnext on Emuelec / Radxa Zero

Successfully built a prototype game console on raspberry pi zero. Now I would like to move to radxa but when I run GPIOnext/ after cloning github there is an error saying sudo is unnecessary etc. I suspect GPIOnext project is incompatible with Radxa and I would like to know how you people go around this issue when migrating. I need EMUELEC to recognize my GPIO based input, which works perfectly in Retropie.

Thank you.
