what is project-liminal-gate fr?

Project Liminal Gate is a local compatibility server designed to keep an older mobile game, Terra Battle, playable after its original online servers are no longer available. It runs on your own computer and lets an existing copy of the game client connect to your machine instead of the official servers. The project is currently a tester build. The verified playable path reaches and clears the early stage called Chapter 2-1, with guided setup enabling progression through later chapters up to Chapter 42. The developers note that not every later reward, drop, or scripted scene is guaranteed to work perfectly, and some stages may need individual fixes. The setup also enables two local features called the Pact of Fellowship and the Pact of Truth. The first uses Coins, and the second uses Energy, with new local accounts receiving 50 free Energy to start. Certain game variants like Fate, ticket, campaign, and event Pacts are intentionally unsupported. You can test the project on an Android emulator or on a physical phone or tablet. The developers encourage reporting any Network Errors through GitHub issues, including details about the action taken, the operating system, device version, and relevant log lines. Getting started requires several tools installed on your computer. You need Python 3.11 or newer, Android Studio with its emulator and SDK tools, Android SDK Platform-Tools, Android SDK Build Tools, and a JDK for creating a local signing key. You also need a local copy of the Terra Battle Android 5.5.7-170 APK and its matching resources. The repository does not include the APK or game resources, and all such files should be kept outside of Git on your own machine. The guided setup process helps configure the Android emulator and signing tools. It checks for the necessary Android SDK components and can recognize standard installation locations on macOS, Linux, and Windows. The developers recommend using a Pixel 6 emulator with Android 12 as a baseline, since some newer Android system images can cause the original game to crash on emulators. On macOS specifically, the emulator should be started with a software graphics backend to avoid a permanently black screen. The full README is longer than what was shown.
