The Xbox Adaptive Controller (XAC), released on September 4, 2018, is a video game controller designed by Microsoft for Windows PCs and the Xbox One and Xbox Series X/S consoles.
It is a unified hub for devices that helps make gaming more accessible for gamers with limited mobility, allowing them to connect external devices such as switches, buttons, mounts, and joysticks to create a custom controller experience.
As the XAC should be interpreted we `Xbox Wireless Controller` the RetroDECK team don't see any reason why this should not work with RetroDECK right out of the box.
