Issue with button mapping

[Goldfire345]

hello I'm no sure if i've ever left an issue here before but here goes lately i've been trying to map the controls so i can use the touch screeen and stylus with my left hand and move with the face buttons as i am left handed, but while im able to map the b,x and y buttons the game will not let me map the a button to any controls even when i write it as mapped into the config file and it shows as mapped in game

furthermore its as if the game itself does not see the a button as a button at all

I am 100 percent sure my a button is not broken becuase itt functionin literally every thing else. Home menu other games other homebrew apps including quake 2.

for context i am using a new 3ds xl. I've tried everything i can think of but the game just does not seem to recognize this button despite the readme on the page saying it can be used for camera control, was there a change that removed the games ability to recognize this button on a new 3ds model or something? because it seems like to this game the a button is completely invisible
