This guide focuses on using patch.tjs and xp3filter.tjs to run encrypted KiriKiri (XP3)
visual novels on mobile emulators like Kirikiroid2. These scripts essentially act as a "key" that tells the engine how to decrypt game data on the fly. 1. Understanding the Files
patch.tjs: The main script that intercepts the game's startup process and instructs the engine to use a custom decryption filter.
xp3filter.tjs: The specific script containing the decryption logic (often a XOR operation) and the unique "key" required for your specific game. 2. Implementation Steps To apply these to a game that won't run due to encryption:
Locate the Game Folder: Open the main directory where the .xp3 files (like data.xp3) are located.
Place the Scripts: Drop both patch.tjs and xp3filter.tjs directly into this root folder.
Configure the Filter: If you have a specific decryption key, open xp3filter.tjs with a text editor. Ensure it contains the setXP3ArchiveExtractionFilter function. Example code snippet: javascript
Storages.setXP3ArchiveExtractionFilter(function(hash, offset, buf, len) buf.xor(0, len, 0xKEY); // Replace 0xKEY with the actual hex key ); Use code with caution. Copied to clipboard
Run the Game: Launch the game executable (or the folder in Kirikiroid2). The engine will read patch.tjs first, which then loads the filter to decrypt the archives as they are accessed. 3. Alternative for Stubborn Encryption
If standard scripts don't work, you may need to "pre-decrypt" the files:
Extract and Repack: Use tools like KrkrExtract to fully unpack the .xp3 archives into raw folders.
Remove Encryption DLLs: Some games use a specific .dll (like krkrsteam.dll) for encryption. Removing these and using decrypted files can bypass the need for a filter script.
Unencrypted Archives: Tools like Xp3Pack can create archives with zeroed hashes to skip the game's internal decryption entirely.
patch.tjs and xp3filter.tjs are core script files for the Kirikiri (krkr) game engine, frequently used in visual novels. They are primarily used by enthusiasts and developers to modify games or run them on mobile devices via the Kirikiroid2 emulator. 🛠️ Purpose of the Files
These .tjs (TJS2 script) files handle how the game engine interacts with its resource archives (.xp3 files). xp3filter.tjs
Decryption: This is the primary tool for decoding encrypted .xp3 archives.
XOR Keys: It often contains a specific decryption key (XOR key) that allows the engine to read protected game assets like images, scripts, and audio.
Custom Filters: Developers use Storages.setXP3ArchiveExtractionFilter within this file to apply custom extraction logic.
Startup Hook: The engine automatically executes patch.tjs if it exists during the startup process.
File Overriding: It is often used to tell the engine to look for specific "patch" archives or folders (like patch.xp3) before the main data.xp3.
Regional Fixes: It can help bypass region-locking or locale issues by modifying how the engine initialises. 📱 Use in Mobile Porting (Kirikiroid2)
When running PC visual novels on Android using Kirikiroid2, these files are often mandatory:
Fixing Crashes: Some games (e.g., Fate/Stay Night Realta Nua) require specific patch.tjs files to prevent crashes at specific points, such as the end of a prologue.
Installation: Users typically place these two files directly into the root directory of the game folder on their device to enable the emulator to read the game's encrypted content. 🌍 Fan Translation & Modding

The Kirikiri engine, often referred to by its script language TJS (TJS2), is a powerful yet lightweight framework for creating 2D visual novels. Games built on this engine package their assets—images, music, voice files, and logic scripts—into archives with the extension .xp3. To modify a game’s behavior (e.g., fixing bugs, adding translations, or bypassing restrictions), a modder cannot simply edit the original files. Instead, they rely on two critical hook files: patch.tjs and xp3filter.tjs. These files act as gatekeepers, intercepting the engine’s file access requests and redirecting them to modified assets.

These files are used by enthusiasts and developers to modify visual novels or ensure they run on mobile devices.
Patch.tjs: This is a standard Kirikiri script file used to apply updates, bug fixes, or translations to a game. It acts as an override; when the engine finds a patch.tjs or a file within a patch.xp3 archive, it prioritizes that data over the original game files.
XP3Filter.tjs: This script defines the decryption filter for XP3 archives. Many Kirikiri games use custom encryption (often a simple XOR cipher) to protect their assets. The xp3filter.tjs tells the engine how to unscramble the data as it is being read from the disk. Key Concepts and Implementation
If you are looking for documentation or technical details on these topics, you can find them in community repositories and developer guides:
Writing XOR Patches: Users often create their own xp3filter.tjs by identifying the XOR key used by a specific game. This is frequently done using tools like KrkrExtract or GARbro to dump decrypted memory.
Kirikiroid2 Compatibility: Many custom patches for mobile ports are hosted on the Kirikiroid2_patch GitHub repository, which contains specific xp3filter.tjs examples for various visual novel titles.
Unencrypted Overrides: To bypass complex encryption, some users utilize the KirikiriUnencryptedArchive plugin, which allows the engine to read raw, unencrypted files from a specific folder instead of the original archives.

Understanding Patch.tjs and XP3Filter.tjs in Kirikiri Engine Patching
In the world of visual novel (VN) translation and technical modding, the Kirikiri (krkr) and KAG (Kirikiri Adventure Game) engines are industry staples. When users attempt to apply translation patches or run PC-exclusive games on mobile via emulators like Kirikiroid2, two specific script files often appear: patch.tjs and xp3filter.tjs. These files are the "keys" to bypassing encryption and organizing how the game reads its external data. 1. What is Patch.tjs?
The patch.tjs file is a script used by the Kirikiri engine to modify the game's behavior without altering the original core files.
Override Mechanism: Kirikiri looks for a file named patch.tjs (or archives named patch.xp3) during startup. If found, the engine executes this script to override or "patch" existing functions in the game's memory.
Asset Redirection: Its primary role in translation projects is to tell the engine to look for translated scripts, images, and fonts in a new directory or archive rather than the original data.xp3.
System Fixes: It is frequently used to fix compatibility issues, such as text wrapping errors, locale-specific crashes, or adding support for modern screen resolutions. 2. What is XP3Filter.tjs?
The xp3filter.tjs file is a specialized script designed to handle encrypted XP3 archives. While the standard Kirikiri engine can read uncompressed files, most commercial visual novels encrypt their assets to protect intellectual property.
The Decryption Hook: This file contains the "filter" logic—specifically a decryption key or algorithm—that the engine uses to read the scrambled data inside an .xp3 file in real-time.
Emulator Support: For users of emulators like Kirikiroid2, an xp3filter.tjs tailored to a specific game is often required to "unlock" the game's assets so the emulator can display text and graphics.
Signature Matching: Each game often has its own unique encryption method. Therefore, an xp3filter.tjs from one game will rarely work for another unless they share the same developer or engine version. 3. How They Work Together
In a typical patching or emulation scenario, the two files function as a duo:
Unlock: xp3filter.tjs provides the engine with the means to decrypt the original game archives.
Redirect: patch.tjs instructs the engine to ignore specific original files in favor of the new, translated ones. Primary Function Common Format XP3 Archive Stores game assets (images, script, BGM) .xp3 Patch.tjs Logic for overriding game functions .tjs XP3Filter.tjs Logic for decrypting locked archives .tjs 4. Common Troubleshooting for Patches
If you are trying to use these files to play a game and encountering errors, consider the following:
File Placement: Both files should typically be placed in the root directory of the game (the same folder as the .exe file).
File Naming: Ensure the names are exactly patch.tjs and xp3filter.tjs. Some systems might accidentally append a .txt extension (e.g., patch.tjs.txt), which will prevent the engine from recognizing them.
Version Mismatch: Ensure your xp3filter.tjs matches the specific version of the game. For example, a Steam release might have different encryption than an original physical disc release.
Tools for Extraction: If you need to see what is inside these archives yourself, developers recommend using tools like GARbro or KrkrExtract to handle the unpacking process.

Because these terms are highly technical and niche, this essay will explain their origin, function, and the typical context in which users encounter them: game modification (modding), translation, and reverse engineering.
.xp3 Archives)The Kirikiri engine uses a proprietary archive format called XP3. This functions like a .zip or .pak file, storing game assets (scripts, images, audio).
Kirikiri is unique because it doesn't just store binary data; it relies heavily on a scripting language called TJS (a JavaScript-like language). The engine compiles these scripts into bytecode (often seen as .tjs or scrambled inside the archive).
Place both files in the game’s root directory (where the original data.xp3 resides).
Ensure xp3filter.tjs contains valid redirect rules, e.g.:
// Example xp3filter.tjs entry
Storages.addFilter("scenario.ks", "patch/scenario.ks");
Note: These scripts are specific to the Kirikiri (TJS2) engine. Incorrect syntax can cause game crashes.
