About

When two or more buttons are pressed on the same frame, the game
doesn't handle each press properly except the one checked last.
When the character stands or walks, the game checks if buttons
are pressed in the following order:

	1. A button
	2. B button
	3. Down button
	4. Left and Right buttons
	5. Start button*
	6. Select button*
	
* The last two seem not to influence.

When two buttons are pressed simultaneously, such an order creates
the following issues:

   A + B		the character attacks but not jumps
   A + Down		the character sits down but not jumps
   A + Left		the character moves left but not jumps
   A + Right	the character moves right but not jumps
   B + Down		the character sits down but not attacks
   B + Left		the character moves left but not attacks
   B + Right	the character moves right but not attacks
Down + Left		the character moves one pixel left then sits down
Down + Right	the character moves one pixel right then sits down

Fortunately, reversing the order of the first four checks fixes
most of the issues. So now:

   A + B		the character jumps but not attacks**
   A + Down		the character jumps then sits down
   A + Left		the character jumps and moves left
   A + Right	the character jumps and moves right
   B + Down		the character attacks and sits down
   B + Left		the character attacks and moves left
   B + Right	the character attacks and moves right
Down + Left		the character sits down and turns left (not moves)
Down + Right	the character sits down and turns right (not moves)

** Although this may still seem like an issue, it is not due to
the check order and occurs even if the buttons were pressed on
different frames within a short period of time.
