How in the world do i get MayFlash Genesis Controller recognized?

Hi there,

Great day to you, soo… Big Box will let me navigate with the Joystick, however when opening / selecting games, i do not see Retroarch showing it as an option to choose the MayFlash / Genesis Controller

I have tried all modes, Red, Green and Blue, with PC Xinput and Dinput

What would i do to make this work ? I just want Retroarch to recognize this as an option as a controller
