Following up 91's open items.

Jumps that never landed. A test of a standing jump on level 3 found the player hanging 3 above the floor in Fall, with the fall speed growing and the stick doing nothing. The same happens on the committed code before 91. The cause was the step that would cross the floor: it ends below the floor, the floor probe there is inside the ground (kind non-zero, no tile), and the port put the body back where the frame began, 3 short, every frame. The original lands when y + vy reaches the floor (0x8005f1b4). Now a descending step that would end in the ground lands on the floor under where the step began.

The landing animation. The port went from Land to Stand on the landing frame, because the check asked whether LAND was playing before it had been asked for. Land now holds until its animation (logical 4, table 8) has played. The jump now runs 5, 6, 8, 0, as in the oracle.

Entry sounds (0x800562bc, positional via 0x8006f644). They play when a body's base track enters a table state:

• 6 entering 6 or 41: a standing jump's fall half, or a moving jump at once. The port used to play 6 at every take-off.
• 11 entering 8: landing.
• footsteps entering the walk's halves 1 and 2, only for Spike in levels 9 and 14 (132) and characters 47 (166), 33 (164) and 22 (165). The babies have none.

Animator::take_entered hands over the states entered; Game plays their sounds at the player and at every shown NPC. The test a_jump_sounds_at_its_states checks 6 after the take-off and 11 on landing.
