# Stage 4 objects through Stage Select Mode, without play (player 1 stays at the start; vitality refilled
# every 120 frames). A poke at frame N acts on the code of frame N + 1.
# - 3627: event 0C (the door at the start of stage 4): the third door roller (2033E0), dropping out of
#   the doorway, moved 300 along -x: there is no floor under it, it falls to z 800 and is removed
#   (082B26; door_roller_layout drops the four onto the floor).
# - 3700/3701: a by-handler list in free RAM (20B000) and the by-handler cursor (20F0DA): an arrow board
#   on a crumbling floor, a kind 0 catapult (launch delay 400), a kind 1 catapult on no platform, a
#   propped board over player 1, group leader hold records 0 and 2, a kind 8 sign, and at scroll 0190 a
#   second kind 0 catapult (spawned at 3709).
# - 3709: free object count (20E900) 0 for frame 3710, when the second catapult lands on its platform
#   and needs a block for its base part: it is removed (080F8F). 3710: the stack as it was plus the
#   catapult's block (count 46, slot 1 back to 0000, slot 46 = 3340).
# - 3720/3721: a group record of type 2 (no stage lists one: three crumbling floors, leader 0, floor block
#   1E4, 45 apart in x, at scroll 0100) at 20B100 and the group cursor (20E55C) pointed at it (091262,
#   0912D0, 091455).
# - 3730: the hold objects (202EE0 kind 0, 2032A0 kind 2) turned to directions 0 and 3, which no
#   group_leader_hold_records entry has (coordinate 0, leader 0 for the first).
# - 3735: the propped board (202BC0), touched by player 1 while falling, moved aside and stopped (speed_z
#   0, group_leaders[1] = the stage's leader 0 at 204B00) so that its shake runs to the end.
# - 3740: the kind 0 catapult (2028A0): its launch position (36) moved to the current scroll position.
# - 3750: sign_stop_flag (20E5F4, nothing writes it) = FF: the kind 8 sign is removed.
# - 3800-3860: player 1's field 9F (nothing sets it) = 1: grey screen (update_grey_screen).
