+; this function is used when lower button sensitivity is wanted (e.g. menus)
+; OUTPUT: [hJoy5] = pressed buttons in usual format
+; there are two flags that control its functionality, [hJoy6] and [hJoy7]
+; there are essentially three modes of operation
+; 1. Get newly pressed buttons only
+;    ([hJoy7] == 0, [hJoy6] == any)
+;    Just copies [hJoyPressed] to [hJoy5].
+; 2. Get currently pressed buttons at low sample rate with delay
+;    ([hJoy7] == 1, [hJoy6] != 0)
+;    If the user holds down buttons for more than half a second,
+;    report buttons as being pressed up to 12 times per second thereafter.
+;    If the user holds down buttons for less than half a second,
+;    report only one button press.
+; 3. Same as 2, but report no buttons as pressed if A or B is held down.
+;    ([hJoy7] == 1, [hJoy6] == 0)
