Hyperkin GN6 Sega Genesis 6 Button Controller Support

Testing the two controller USB Genesis Adapter

With a sega branded 3 button controller, all of the inputs work: (D-Pad, start, ABC) With a Hyperkin GN6 6 button controller (works fine on console), only The D-Pad and the BC buttons work. Start, A, mode, and XYZ do not work.

Tested on windows with gamepad properties and on a Mister. Tested with two different GN6 controllers and a single OG genesis controller.

Checked pin outs with a multimeter and everything looks good. Used arduino IDE to upload the latest sketch.

Need to get an official sega 6 button controller to test more, but I wanted to check in here to see if there were any ideas. The Hyperkin GN6 is a great alternative to aging controllers that have gone mushy, and they work fine on console. Curious if there are any reasons why the adapter might see it differently.
