This octopod version works on official MiSTer. Also on my MiSTer models (SLIM, DRIVE, MINI and PLUS), PC, raspberry or other devices with USB support. Based on daemonbite firmware, modified by GAsinPrieto and tested by Oskarz. Firmware can be upgraded from here. It supports 2 NES, 2 SNES, 2 NeoGeo and 2 Genesis controllers. As the PCB and case are the same, SNES position is marked with PSX. USB cable is included with the cased option.
All controller ports can be plugged in at the same time, but only the 2 ports selected by the top switch will work in tandem. To switch between controllers unplug the USB, change the switch and plug the USB again.
