Default button mismatch

I have a particular irrutation that I must share. I think it’ll make me feel better. The “A” and “B” buttons on the Nintendo DS are opposite those of the XBox 360. Since the 360 was first, I blame Nintendo.
Since I play both often, it makes it hard to play some games since “B” usually means “Cancel” and “A” usually means “Select”.
Irritating at the least.
