What is angrybirdsclassic_nx?

This project is a native wrapper that lets the original Angry Birds Classic game run on a Nintendo Switch through homebrew software. It is important to understand what it actually contains: no game code and no game assets. Instead, it loads the game's own native library file and rebuilds, in native code, the small layer of Android system calls the game normally expects to find, things like a fake Java environment, graphics context, audio device, and input handling. You have to supply the actual game library and asset files yourself, taken from a copy of Angry Birds Classic that you legally own. To use it, you copy the wrapper's .nro file onto your Switch's SD card, then place the game's library file and its full assets folder in that same location, both extracted from your own copy of the Android APK. There is a specific folder layout the README lays out, and it notes the 64-bit version of the library is required, the older 32-bit version will not work. Once running, the game can be controlled with the Switch's joysticks, buttons, motion controls for aiming, or even a USB mouse in handheld or docked mode, with sensitivity settings that get remembered automatically. The wrapper also supports several UI languages, either following the Switch's system language automatically or set manually through a configuration file, covering languages such as French, German, Spanish, Portuguese, Russian, Japanese, and both simplified and traditional Chinese. Building it from source requires devkitPro with its Switch development tools and several supporting libraries. The project credits its underlying loader infrastructure to an earlier open-source Switch port of a different game, all under the MIT license, and it separately bundles two small public-domain libraries for compression and encryption used by an optional language patching feature.
