What is am2r-autopatcher-android?

This tool converts your own legally owned copy of the fan game AM2R version 1.1 into an Android app, doing all the work directly on your device. Nothing playable is included in the project itself. Instead, the patcher takes the original game files you already own and rebuilds them into an installable Android package, checking the result byte for byte against the official checksum before saving it, so you know the output matches the real release exactly. To use it, you need your own copy of the original 2016 freeware release of AM2R 1.1, since modified or updated community versions will not work with this patcher. On Windows, you simply run the included program. On Linux or macOS, you need Python 3.8 or newer along with a tool called xdelta3, which handles applying binary patches. After running the patcher and pointing it at your game file, it produces an Android app file within about a minute, along with a checksum you can compare to the one published in the official release notes. Once the app file is created, you copy it to your Android phone and install it like any other app from outside the official app store. If you already have an older version installed, updating this way keeps your saved progress intact. Under the hood, the patcher works by combining three pieces: a wrapper file containing the Android version's engine and code with the original game's content removed, a binary delta file that reconstructs that missing content from your copy of the game, and a plan file that checks every piece along the way. Because the process rebuilds the game data byte for byte, the resulting app carries the same official signature as if you had downloaded it directly. This project is aimed at existing AM2R players who want to run the fan game on their Android phone using only their own legitimately obtained game files, drawing on the design of an earlier Windows version of the same idea.
