Final Fantasy III: Trigger Happy is a bug fix patch for the Super Nintendo game Final Fantasy III. It addresses issues in Zone Eater Cave where a falling ceiling can kill players despite triggering safety tiles. The patch modifies the event handling to ensure tile-based events activate correctly, preventing unintended character movement and deaths. The patch is compatible with headered and non-headered ROMs.
In Zone Eater Cave, there's a room with a ceiling that falls every four seconds or so. The game uses tile-based event triggers to determine if you avoid being crushed, except that if the ceiling's timer expires at the wrong time, it supersedes the tile-based event triggers and prevents them from declaring you safe, meaning that you can die even if the ceiling misses. It also means you can survive even if you get crushed, or that Terra can bypass the exits to the room and walk about the darkness without falling. This patch makes the ceiling respect tile-based event triggers.

PATCH INFORMATION:
SNES patches work on ROM v1.0 or v1.1.
URGENCY:
Medium. Specific to only one location, but could be serious under the right circumstances.
PURPOSE:
The room inside Zone Eater Cave that contains a falling ceiling, though clever, is also problematic. The ceiling is controlled by a timer, and it falls as soon as the timer expires. There are a few tiles that activate auto-resetting flags that determine if the player is safe, so if you're standing on one of these tiles, you'll end up going through the allowed holes instead of getting crushed. However, if you step onto one of these tiles at the very last second, the ceiling will fall before the tile has a chance to trigger its event script, meaning that you can be killed despite being clear of the ceiling. This patch modifies the ceiling fall event to allow tile-based events to trigger beforehand.
The worst effect of this bug is that Terra can bypass the event triggers at the exits to the room, which allows her to wander anywhere on the map and venture way out of bounds. This works because of a secondary bug that causes her to take an extra step when the ceiling falls. Although this patch does not fix that bug, it is enough to prevent Terra from bypassing those event triggers on the exits.
