- Imported from https://github.com/supermegamestre/Project-Real-Resurrection-3 - APKTool decompilation (Smali bytecode) for modding and rebuilding APK - Supports both 32-bit (armeabi-v7a) and 64-bit (arm64-v8a) architectures - Includes full Smali source, resources, and native libraries - Ready to rebuild APK after modifications with apktool b command - Added comprehensive README-apktool.md with modding guide This branch complements the JADX branches: - Use JADX (main/discord-community) to UNDERSTAND code (readable Java) - Use APKTool (this branch) to MODIFY and REBUILD APK (editable Smali) Total: 44,417 files, 538.51 MB Smali source code
