More about this app

Mod manager for the game 'Last Origin'

Overview

A simple APK to quickly apply Mods for the game Last Origin.

Require Android version 7 or above. Tested and working for Android 12 and some Android 13.

With Shizuku installed, the app can also use ADB to install patches for Android 11 to 14.

This project is experimental, and game patching is not supported by developers.

USE AT YOUR OWN RISK!

Does not work for Samsung Android 12? (Need more testings)

Attentions

Experimental, might not work on some phones. Contact me on Discord (Altter#7252) if you encounter any errors.
Make sure to let the game download all its assets before patching.
- Weekly updates might cause some of the files to be replaced. You can use the APK to apply Mods again.
The folders inside the Mod Folder should have the correct name corresponding to the one to be replaced inside /files/UnityCache/Shared folder.
The asset must be named __data. It must also be at most 1 subfolder deep inside the Mod folder.
- For example, both Mod Folder/localization/__data and Mod Folder/localization/gibberish/__data will correcty place the mod inside localization folder, but not Mod Folder/localization/gibberish/gibberish 2/__data
(For Android 10 or above) There must be only one subfolder inside the modded folder, __data must also exist already inside that folder.
If anything break, delete the modded folders inside /files/UnityCache/Shared, then reopen the game to download assets again.

How Shizuku is used

Can install and clear Last Origin mods by copying and removing game cache files via `ls`, `cp` and `rm` through Shizuku.

This is an AI-assisted analysis of Shizuku-related usages in the app's public source code. It is best effort, so it may not catch every single usage.

How this app uses Shizuku

Shizuku lets the app directly read and change the game mod folders and Unity cache files without manual folder access. The privileged shell runs fixed file commands supplied by the patch feature.

Install game mods: copies the selected mod __data file over the matching game cache __data file with the cp shell command through Shizuku.
Clear installed mods: deletes the patched game cache __data file with the rm shell command through Shizuku, zeroing the file with cp from /dev/null when deletion is blocked.
Browse mod and game files: lists mod folders and game cache folders and checks that paths exist with the ls shell command through Shizuku to find install targets.

Android APIs or commands used

sh
ls
cp
rm

Notable details

Without Shizuku the same install and clear actions still work through system folder access or direct file access, depending on Android version. Shizuku simply avoids manual folder grants by using direct file paths.

Changelog

What's new for version 1.3.1

Fixed: When multiple game versions are enabled, only the first one would be patched due to FUSE transport disruption after cp
Fixed: "More than one file or folder" error - now correctly finds __data in the valid Unity cache subfolder (identified by __info)
Improved: Shell commands now use a persistent session to reduce process spawning
Improved: Better error logging showing platform name, source and destination paths per copy attempt
