Proto:The Legend of Zelda: Ocarina of Time Master Quest/Event Editor

This is a sub-page of Proto:The Legend of Zelda: Ocarina of Time Master Quest.

Description

Ocarina of Time uses flags in order to track which events have occurred in a playthrough. When the player takes certain actions, such as triggering an event that advances the plot, talking to a particular NPC, or obtaining a particular item, the flags linked to these actions will change from 0 to 1. The Event Editor allows the flags to be turned off and on manually, affecting what the game thinks the player has done in their save file.

Flags are categorized by four different types of tables, described in their respective sections. Each table contains 0x0F (16) flags, represented by zeroes. For example, the last zero in event_chk_inf[4] is the flag that tracks whether or not Link has received Zelda's Letter. Changing this flag from 0 to 1 makes the game believe that the aforementioned event has occurred.

Haven't Received Letter	Have Received Letter
event_chk_inf[4]	event_chk_inf[4]
0000 0000 0000 0000	0000 0000 0000 0001

Mapping Flags

If you plan to test event flags in order to find out what triggers them, you may want to keep the following in mind:

1. Sometimes, a single action turns on more than one event flag. Each time you perform an action, check every flag table to make sure you don't miss any!
2. The Debug ROM's save file already has some flags set by default. Every time you use map select, the flags will be reset to these defaults. You can avoid the flags resetting by using an exit code to travel around the game, rather than map select.
   • Use these codes with an Exit List.
   • Edits Fairy Fountain -> Ganon's Castle Exit (Adult): 813C0288 XXXX
   • Edits Gerudo's Fortress -> Gerudo Valley Exit (Child): 813BE534 XXXX
3. Using the event editor to turn on an event flag for receiving an item won't make that item appear in your inventory. Items must be added manually via the inventory editor.

Happy hunting!

Flags Referenced Outside Early Text Routine

22

This flag is defined by the early flag list as "Darunia Approves Use of Bomb Flowers". En_Du, Darunia's actor, contains code which sets the flag after Darunia says the following message (which was overwritten with Darunia's response to Link playing a melody other than Saria's Song).

ID	Message
3020	Well, that's not quite what I was looking for... I wanted to hear...a tune... something...um...from outside the mountains...something... green...natural... That's the kind of music I want to hear...

It's also referenced by the early text routine.

In the final game, the flag is never read from.

4C

This flag is not defined by the early flag list. Demo_Im, Impa's actor, contains an unused function that checks whether Link has obtained Zelda's Letter, then branches to the unused function which sets the flag.

Missing Flags

For whatever reason, entering the following locations doesn't set any particular flag:

• Spot 03 - Zora's River
• Spot 04 - Kokiri Forest
• Spot 05 - Sacred Forest Meadow
• Spot 10 - Lost Woods
• Spot 13 - Haunted Wasteland
