The problem itself:
I was going to play the NS version of "My Big Sister" on my Android tablet. But when I tried to map gamepad controls, I stuck upon some strange behaviour: the right and middle button sets aren't working in some cases, while the left button set does work in these very cases.

The example is: I've mapped "confirm" action to "Joy A" button, then tried to confirm "New Game" button in the main menu. But it didn't budge, nothing happened. I tried mapping Joy B, Joy X, Joy Y, left and right sticks, nothing worked. But! Then I tried something strange: mapping "confirm" action to "D-Pad Down" button. And it worked! For some reason, it matters for the game what set of buttons I map to an action, when it shouldn't matter in reality.

A demonstration video is attached.
