Yeah, I think if controllers just connected or started with Minus pressed so B is on the left, A on the bottom, X on the right, Y on the top would be quite a good QOL improvement. Not that it took too long though xD but I think players who have friends come over and bring out 4 controllers but friends don't know to press Minus so they had to go and press Minus on friends controller would appreciate
Also your previous changes somehow broke return shortcut function. When launching GC backups from USB Loader GX and then returning to it by pressing B+Down+R+Z freezes WiiU console. I reverted back to regular Nintendont and it doesn't happen.
