Hello, I am announcing that matches have successfully been played in free battle mode using the Polaris server.
github.com/polaris-/dwc_network_server_emulator/wiki

Much work was done to make this happen, you can view some of the issues and the final solve here:
github.com/polaris-/dwc_network_server_emulator/issues/29

I do not know how relevant this is to the work being done by Wiim but I think sharing is best and you have "smt-ddr" as a resource if you choose to add Tatsunoko vs Capcom to the wiimfi server.
