# The how-to-play intro (game mode 1, stage 7, after the character select of a new game): its
# objects (button hand, trackball hand, control panel) remove themselves when the stage is not 7,
# which never happens while they exist (start_stage resets the object list before any other stage
# runs). Pokes (a poke at frame N acts on the game code of frame N + 1):
# - 2555/2556: free_object_stack_2 (20EA10, the second pool's count) 0 for the frame the trackball
#   hand starts (2556): it gets no ball (field 28 = 0, 083F98). Count restored (FC).
# - 2700/2701 and, in a second game, 4740/4741: stage (20F06E) 06 for one frame: the three objects
#   remove themselves (083D43, 083E41-083E55 with and without the ball, 083FCB).
# - 3900: player 1's player_status (20E590) 0 in stage 5: game over; a start (3960) begins game 2.
