Dual DB9 joystick adapter for Genesis controllers. Designed for ESPectrum, but can be used with another devices. It supports two protocols (USB and PS/2) selectable by the switch. For using in ESPectrum select the PS/2 option. For use in MiSTer select USB one. With the original firmware designed by David Carrión it emulates HID Keyboard, so you can use in MiSTer with Computer cores. Here is the original firmware:

But you can also install the Daemonbite firmware from here and it will work as HID gamepad, and PS/2 protocol won’t work.
