ZoraSharp

A library for working with the password system used in the Legend of Zelda Oracle of Ages and Oracle of Seasons games. Inspired by the original password generator written by Paul D. Shoener III a.k.a. Paulygon back in 2001.

The name comes from a contraction of Zelda Oracle and from the Zora, one of the games' races and enemies.

User Interfaces

ZoraSharp is only a library for manipulating the codes from the Oracle series games, meant for use by developers. General users should instead use of the the following user interfaces:

• Windows WPF - https://github.com/kabili207/zoragen-wpf
• Linux GTK - https://github.com/kabili207/zoragen-gtk
• Blazor Web App - https://github.com/friendlyanon/zoragen-blazor

Features

• Decodes game and ring secrets
• Generates game, ring, and memory secrets
• Allows import and export of game data using a json-based .zora file

Using the library

Full documentation for the current stable release of ZoraSharp can be found at http://kabili207.github.io/zora-sharp/api-doc/. Below are functions to handle the most common scenarios.

Regions

There are two supported regions, US and JP. (The PAL region is nearly identical to the US region for the purpose of secrets.)

Getting the raw secret

ZoraSharp uses byte arrays for most operations with the secrets. Most people don't go passing byte values around, however, opting for a more readable text representation. These secret strings can be parsed like so:

string gameSecret = "H~2:@ left 2 diamond yq GB3 circle ( 6 heart ? up 6";
byte[] rawGameSecret = SecretParser.ParseSecret(gameSecret, GameRegion.US);

The ParseSecret method is fairly flexible in what it will accept. Possible formats include 6●sW↑, 6 circle s W up, and 6{circle}sW{up}. You can even combine the formats like so: 6cIrClesW↑. Brackets ({ and }) also ignored, so long as they are next to a symbol word such as circle or left.

Whitespace is also ignored. This does not cause any issues with the symbol words because the list of valid characters does not include any vowels.

Getting a secret string

It's also possible to take the raw bytes and convert them back into a readable string value.

byte[] rawSecret = new byte[]
{
     4, 37, 51, 36, 63,
    61, 51, 10, 44, 39,
     3,  0, 52, 21, 48,
    55,  9, 45, 59, 55
};
string secret = SecretParser.CreateString(rawSecret, GameRegion.US);
// H~2:@ ←2♦yq GB3●( 6♥?↑6

The CreateString method is far less flexible than it's counter-part, and will only return a UTF-8 string, as shown above.

Loading a secret

Secrets can be loaded from a string...

string gameSecret = "H~2:@ left 2 diamond yq GB3 circle ( 6 heart ? up 6";
Secret secret = new GameSecret();
secret.Load(gameSecret, GameRegion.US);

...or from a byte array

// H~2:@ ←2♦yq GB3●( 6♥?↑6
byte[] rawSecret = new byte[]
{
     4, 37, 51, 36, 63,
    61, 51, 10, 44, 39,
     3,  0, 52, 21, 48,
    55,  9, 45, 59, 55
};
Secret secret = new GameSecret();
secret.Load(rawSecret, GameRegion.US);

Loading a ring secret

// L~2:N @bB↑& hmRh=
byte[] rawSecret = new byte[]
{
     6, 37, 51, 36, 13,
    63, 26,  0, 59, 47,
    30, 32, 15, 30, 49
};
Secret secret = new RingSecret();
secret.Load(rawSecret, GameRegion.US);

Creating a game secret

GameSecret secret = new GameSecret()
{
    GameID = 14129,
    TargetGame = Game.Ages,
    Hero = "Link",
    Child = "Pip",
    Animal = Animal.Dimitri,
    Behavior = 4,
    IsLinkedGame = true,
    IsHeroQuest = false,
    WasGivenFreeRing = true
};
string secretString = secret.ToString();
// H~2:@ ←2♦yq GB3●( 6♥?↑6
byte[] data = secret.ToBytes();

Creating a ring secret

RingSecret secret = new RingSecret()
{
    GameID = 14129,
    Rings = Rings.PowerRingL1 | Rings.DoubleEdgeRing | Rings.ProtectionRing
};
string ringSecret = secret.ToString();
// L~2:N @bB↑& hmRh=
byte[] data = secret.ToBytes();

Creating a memory secret

MemorySecret secret = new MemorySecret()
{
    GameID = 14129,
    TargetGame = Game.Ages,
    Memory = Memory.ClockShopKingZora,
    IsReturnSecret = true
};
string secret = secret.ToString();
// 6●sW↑
byte[] data = secret.ToBytes();

The .zora save file

The .zora file contains all relevent information to recreate a player's game and ring secrets. Data is saved as a JSON object, with the intention that it can be used with other implementations of the password system.

{
    "Region": "US",
    "Hero": "Link",
    "GameID": 14129,
    "Game": "Ages",
    "Child": "Pip",
    "Animal": "Dimitri",
    "Behavior": 4,
    "IsLinkedGame": true,
    "IsHeroQuest": false,
    "WasGivenFreeRing": true,
    "Rings": -9222246136947933182
}

Valid values for Game are Ages or Seasons. This value refers to the target game.

Valid values for Animal are Ricky, Dimitri, or Moosh.

The rings are saved as a 64 bit signed integer. A signed integer was chosen to maintain compatibility with languages that don't support unsigned integers.

None of the fields are required; the ZoraSharp library will load whatever is present, however the same cannot be guaranteed for other libraries that implement the .zora save file.

Special Thanks

• Paulygon - Created the original secret generator way back in 2001
• 39ster - Rediscovered how to decode game secrets using paulygon's program
• LunarCookies - Discovered the correct cipher and checksum logic used to generate secrets
• Drenn1 - Helped determine what the remaining unknown values represented and added support for Japanese secrets.
