Hi there,
Yes you can use a gamepad/joystick using the USB port, for that you need an OTG cable, nothing more. Gamepad are well detected but joystick don’t, because it’s not supported by default. You can also use bluetooth devices, it works too. So an Android port could be very usefull, especially for my Flight Simulator game on Quest 2! Contact me by PM if you want to learn more about that.
LillianGoulston, I don’t have a mac to make builds on anymore so I’m not sure I could even make a build for it. If you want to try, reach out to me at jwilcox at wisengineering dot com and I’ll try to help you get it building for the mac.
