hello,
Yes if you can do it on the switch controller, it s cool.
I installed your game on my racecab( outrun2 sp with computer, Aganyte circuit board and Njz3 software to can control original wheel and pedals) but i did map button start only. I didn't find the mapping file on the game's folder.
Sorry for my english but i know you understand me!馃槈馃憤
Tomorrow, i will post another picture with your game( it s 11h21 pm here)
