Title: Ocarina of Time Event Bitflag mapping. Post by: mzxrules on May 29, 2010, 03:50:31 AM I decided to map out the various addresses containing game event memory because of a rumor that suggests it's possible to defrost King Zora without blue fire. From what I've seen so far, OoT records events with a single flip of a bit, exactly like how the equipment is stored. However, it doesn't seem like everything is stored in a nice pattern like the inventory stuff is.
Interesting Discoveries In theory, it's possible to obtain the Zora Tunic from King Zora as a Kid. What I did was I showed King Zora the Letter to make him slide over, used a code to reset the flag that tells the game that King Zora moved over, then gave him a second Ruto Letter. Unfortunately, King Zora will not accept a second Ruto Letter once the flag that tells him to slide over is set, meaning it's highly unlikely that we'll be able to get the Zora Tunic this way. 11B4C9 00 Link hasn't left house 01 Saria says Yahoo 02 Talked to Saria once 11B4BD 00 Didn't happen 02 Fairy Ocarina Cutscene 11B4B0 00 Default 80 Talked to Kaepora near the entrance to Koriki Forest 11B4B7 00 Default 20 Nabooru Kidnapped Cutscene 11B50A / 11B50B -- Discovered land, Map Screen 11B4BB 00 Default 02 Lake Hylia visited 04 Gerudo Valley visited 08 Gerudo Fortress visited 10 Lon Lon Ranch 40 Graveyard 11B4BA 00 Default 01 Desert Collossus 02 Death Mountain Crater 11B4B8 00 Default 10 Requiem Cutscene 11B4B9 00 Default 01 Hyrule Field Op Cutscene 02 Death Mountain Trail 08 Kakariko Village 40 Goron City 11B4EE 00 King Zora's Frozen (adult) 01 King Zora Thawed (adult) 02 King Zora Given Zora Armor 11B4AA 00 Default 01 Beat the first Diving Game 11B4AB 00 Default 02 Obtained the Zora Bottle 11B4AB 00 Default 08 King Zora's Butt has moved 11B4C8 00 Default 10 Mido gave his Need Sword & Shield speech 11B4A4 00 Default 10 Met The Deku Tree for the First Time 11B4A5 00 Default 10 Mido Stops blocking the Deku Tree 20 Deku Tree Opens Mouth 11B4AD 00 Default 01 Gotten Zelda's Letter, Impa appears to teach lullaby 11B4AE 00 Default 02 Talk to Impa for the First time, learn Zelda's Lullaby Title: Re: Ocarina of Time Event Bitflag mapping.

Post by: UchihaSasuke on June 05, 2010, 08:01:24 AM what's the event for arwing? doing a barrel roll. finding the flag for the escape sequence would be interesting.

Anyway, I made quite a bit of progress on this. I've mapped out I think all the scene flags for the Fire, Water, Shadow Temples and Dodongo's Cavern, and their skulltula flags. I also mapped out the Deku Tree but I plan on going back for skulltulas. I think that once I map out Jabu, Forest, Shadow, Ganon's Tower, I'll upload the tables to a few places.

Title: Re: Ocarina of Time Event Bitflag mapping. Post by: mzxrules on May 22, 2012, 06:20:07 AM Aside from missing probably the Scarecrow Flags, I believe I have fully mapped out every permanent flag stored for the 8 major dungeons.
All address values are listed via a 4 digit shorthand, based on how they would be stored in the SRAM block in v1.0. Therefore, A5D0 corresponds with offset 0000 into a game file. Actor Bits stores a collection of flags that appear to be either tied to actors, or are stored after the Scene Flag block (as it doesn't seem to have any form to it atm). The Scene Flags sheet contains flags stored within the Scene Flag block. It works like this... each scene is allocated 1Ch bytes for storing permanent flags. The first four flags store whether a chest has been opened. The next 4 are switches which are sort of like your general purpose flags. Locked Doors for dungeons are stored here. The 4 bytes after this are the Clear Trigger Flags... when set, these flags typically cause all enemies within a room to disappear. The 4 bytes after the Clear Trigger flags store Heart Pieces. The next 4 bytes seem to be unused, but the last 8 bytes are used by dungeon maps. The Temp Flags sheet documents the 3 of the 4 temporary switch flags that can be preserved by Farore's Wind. These are grouped by the relative area in which they are unset. One not about the Spirit Temple; If you leave the main entrance the temp switch flags are reset. They are only preserved if you use the secondary exits. Edit: Oh one more important thing. Because it would have been a pain in the ass to describe some 100 something rooms, I refer to dungeon rooms by their internal map number. In v1.0, the the internal map number for the current map is stored at 801DA15F. Alternatively I'd think you can also use some sort of a map viewer. Title: Re: Ocarina of Time Event Bitflag mapping.

Post by: mzxrules on April 06, 2013, 05:32:21 AM So I've been looking into writing a mod, and have been writing a program that can read scene/map data (a program that has helped me tremendously in understanding what causes Wrong Warping to crash). And I've been working towards a few goals, one of which is being able to determine if there are any conflicts between switch flags.
To help improve the documentation of actors, I created a printout showing where every actor is used in a scene or map file, and what values they are initialized to. And then I put it into a table. http://www.mediafire.com/?to0bzej11nig3z4 |
