A Tyrano Save Editor is a tool or web-based utility used to modify save files for games created with TyranoBuilder or TyranoScript. These visual novel engines export games as HTML5/JavaScript applications, storing player progress in structured data formats that can be manipulated to change variables, unlock scenes, or skip gameplay sections. How it Works
Games built on the Tyrano engine typically store save data in the browser's Local Storage (for web versions) or as .sav and .dat files within the game directory (for desktop versions). A save editor works by:
Decoding: Converting the obfuscated or JSON-formatted save data into a readable format.
Variable Editing: Allowing players to change "Flags" (logic switches) or "Variables" (numbers like affection points or money).
Encoding: Saving the changes back into the original format so the game engine can load the "new" progress. Common Features
Flag Manipulation: Instantly toggle switches that determine which story branch you are on.
Stat Editing: Max out character relationship points or in-game currency.
Gallery Unlocking: Manually set variables to true to view CGs or endings without playing through them.
Scene Jumping: Editing the "current label" or "storage" pointer to teleport to a specific part of the script. Popular Tools & Methods
Online Save Editors: Websites like SaveEditor.online or specialized GitHub-hosted tools allow you to upload your save file, edit fields in a table, and download the modified version.
Browser Console: Since Tyrano games are JavaScript-based, advanced users can often open the developer console (F12) while the game is running and manually edit the tyrano.plugin.kag.variable object.
Text Editors: If the save file isn't encrypted, it can often be opened in Notepad++ or VS Code. You can search for specific variable names defined by the developer and change their values directly. Risks and Tips
Backup First: Always keep a copy of your original save file. Corruption is common if a variable is set to a value the game script doesn't expect.
Variable Names: Developers often use Japanese characters or shorthand for variables. You may need to look at the game's scene files in the data/scenario folder to identify which variable controls what.
Game Version: Save editors may fail if the game has been updated to a newer version of TyranoBuilder that uses a different encryption method.

Here’s a helpful feature draft for a TyranoSave Editor:
Feature Name:
Smart Save Decoder & Visual Editor
What it does:
Allows users to open, view, and modify TyranoBuilder save files (typically savedata.dat or numbered save files) without needing to understand the underlying JSON or encrypted data structure.
Key capabilities:
One-click save decryption – Automatically detects and decrypts Tyrano’s default save encryption (if any) and displays human-readable variables.
Flag/Variable table editor – Shows all stored game variables (e.g., f.lovePoints, sf.Chapter, tf.doorUnlocked) in a sortable, filterable table. Users can edit values directly (numbers, strings, booleans).
Scene & label jump – Allows changing the current scene/label so players can resume from any point in the story.
Search and replace across saves – Quickly find all saves containing a specific flag and bulk-update values.
Backup & restore – Automatically creates a .bak file before any save is modified.
Integrity check – Warns if edited values might break game logic (e.g., missing scene, invalid variable type).
Example use case:
A player is stuck due to a bug where f.hasKey was never set to true. They open the save in Tyrano Save Editor, search for f.hasKey, change false → true, save, and reload the game – progressing past the locked door without replaying hours of content.
Target audience:
Optional advanced feature:
Diff view – Compare two saves side-by-side to see exactly which flags changed between checkpoints.
When looking for a "Tyrano save editor," you are likely looking for a way to modify the save files of games created with the TyranoBuilder or TyranoScript engines. Because these engines use a specific format (often .sav files that are internally JSON-based), you have two primary options: using a specialized tool or editing the files manually. 1. Using a Specialized Tool
The most effective community-made tool for this is the Tyrano-Save-Reader.
What it does: It converts the encrypted or structured Tyrano .sav files into readable .json files and vice-versa. tyrano save editor
Key Features: It allows for "live editing," functioning similarly to a cheat engine where you can monitor and change values while the game is running. 2. Manual Editing (Advanced)
If you prefer not to use a separate program, you can sometimes find and modify the save data directly if it is stored in a readable format.
File Location: Save data is typically stored in the game's directory or the user's local app data folder (e.g., AppData/Local/YourGameName/User Data). How to edit: Find the datasc.sav or similar save file. Open it with a text editor like Notepad++.
Note: If the content looks like gibberish, it is likely encoded in Base64. You will need to copy the text and use an online Base64 decoder to see the JSON structure, edit it, and then re-encode it before saving. 3. Developer Options (For Creators)
If you are the developer of the game and want to change how the save system works, you edit the system files directly:
Global Settings: Edit [Project Folder]/data/system/Config.tjs to change general save behavior.
Visual Layout: Edit the HTML files located in [Project Folder]/tyrano/html/save.html and load.html using HTML and CSS to customize the interface.
Styling: Use the tyrano.css file in your project folder to adjust the size, color, and position of save list elements.
Warning: Always backup your save files before attempting to edit them, as incorrect formatting in the JSON structure will cause the game to crash or fail to load.

A Tyrano Save Editor is a vital tool for players and developers working with visual novels created in the TyranoBuilder Visual Novel Studio or TyranoScript. While TyranoBuilder is known for its accessibility, its save files (typically .sav) are often encoded in a way that makes direct manual editing difficult. What is a Tyrano Save Editor?
Tyrano save files are primarily JSON data stored using URL or percent-encoding. This means common characters like @ are converted to codes like %40, making the file unreadable to standard text editors.
A save editor, such as the Galactic647 Tyrano-Save-Reader, provides several key functions:
Decoding/Encoding: Converts encoded .sav files into readable .json and back again.
Variable Manipulation: Allows you to modify in-game variables such as character affinity, flags, or progress without replaying scenes.
Real-Time Monitoring: Some tools feature a monitor function that tracks changes between the active save file and the parsed file, enabling "live" editing. A Tyrano Save Editor is a tool or
Template Support: Advanced versions can parse specific parts of a save file to create templates for multiple projects. How to Use a Tyrano Save Editor
For players looking to modify their progress, the process generally involves these steps:
Locate the Save Files: Find the project's data folder. In Tyrano-based games, save data is often stored within the browser's local storage (for web builds) or specific system folders for standalone applications.
Open the Tool: Load your .sav file into a reader/editor like the Tyrano-Save-Reader.
Edit JSON Values: Once converted to JSON, search for specific variable names. You can change values (e.g., changing a false flag to true or increasing a numerical score).
Re-encode and Replace: Save the modified JSON back into the original .sav format and replace the existing file in the game's directory. Developer Customization of Save Systems
For creators using TyranoBuilder or TyranoScript, "editing" often refers to customizing the save interface itself rather than just the data.

There is no single official "Tyrano Save Editor" – several independent tools exist:
Many users also simply edit the .json or .txt files manually with a text editor (like Notepad++) if the game does not encrypt them.
TyranoBuilder stores saves using JSON-like structures (sometimes with simple XOR obfuscation or Base64 encoding, rarely strong encryption). The save editor essentially:
Even with a perfect Tyrano Save Editor, things can go wrong. Here is how to fix the three most common issues:
Copy the new save01.dat back into the game’s save directory, overwriting the old one. Launch the game. Load your save. You should now have 100,000 gold and a sword.
Locate the save folder – Usually found in:
%APPDATA%\GameName\savedata\~/Library/Application Support/GameName/~/.config/GameName/savedata/Open the Tyrano Save Editor – Load the appropriate save file (e.g., save1.dat, global.dat).
Modify values – Change numbers, check/uncheck flags, or edit text. Eseguire sempre backup e lavorare su copie
Save – Write changes back to the original file (always keep a backup).
