I'm the only one having trouble with two players in Final Burn Alpha/Neo? The joycons/pro controller are well conected but the player two doesnt register anything. I'm not using the split joycons option.
I dont know about firmware version but I dont think that the last one is necessary. Just make sure you have the game updated, last amtosphere and ldn_mitm kip. And one last thing, inside the game do not go to Online, you need to select LAN mode
