Doors now run by their trigger schedules, level 26's roar keeps the original's time, and the npc_check sync is wider. With that, the oracle sweep at SYNCAT=1 has no sound or flight differences left in 24 of the 28 levels it runs.

Doors. The original schedules a door's think in two ways:

• Class 8 (0x80049e18 in, 0x80049e5c out, +0x9c): scheduled while its trigger entry is in. So it starts when the five-a-frame pass reaches it. The port had polled the player's distance; level 3's hinged 160 then started eight frames early and closed (sound 54) early.
• An automatic door (template flag 0x40000000, golf's 770: enter 0x8004f6d8, +0xcc): scheduled on its enter, which leaves the "in" bit clear. So the pass enters it again each time round and never leaves it: it cycles for good once the player has come near.

Game::door_entered does both from the trigger pass; a door off the list keeps the distance test. Level 24's 770 sounds 136 and 135 on its cycle exactly as the original does (doors.md had reckoned 136 never plays).

Level 26's roar (0x80085168, 0x800c4ce4) was right but never synced; Script::set_countdown lets tools set the count (golf's roar, the hub's barks, level 10's lines).

npc_check:

• doors are matched by the nearest object of their template (+0xc0 is not every door's start);
• a door's moving is synced from +0xcc or +0x9c;
• the level's countdown is synced.

The sweep (FLIGHTS, SOUNDS, SYNCAT=1, 300 frames):

• 0 flights and 0 sounds off in levels 1-7, 10-18, 23-31.
• Levels 20 and 21 want CINES=1 (the round starts on cine 63's end): level 20 then matches.
