Tried ds4 and my controller still duplicates. What's your settings in ds4?
I finally found a fix for my duplicate controller issue!
After testing each usb I had plugged in, I narrowed it down to my speakers that were registering as a second controller.
In order to fix it I used HidHide to hide my speakers without muting them, and voila! No more duplicate controllers :3
Played my first few parties tonight and I really loved the game! The only problem I have now is with the controls. What controller is JP and US modeled after? What is the intended controller to use with them? I tried a switch pro controller and the buttons are still super strange. This is a huge problem for the flag raising game where you gotta press the buttons in a clockwise position but it's hard to do that when the buttons aren't even organized in a clockwise position
