This project implements a TJS2 (TJS2100) bytecode decompiler for the Kirikiri visual novel engine, converting compiled bytecode into human-readable and executable TJS2 source code.
用于 Kirikiri（吉里吉里）视觉小说引擎的 TJS2（TJS2100）字节码反编译器，将字节码还原为可读且可执行的 TJS2 源代码。
# Single file / 单文件反编译

已验证涵盖所有TJS2编译器可生成的字节码模式，并已对以下目录中的所有TJS2脚本完成验证测试：
- kag3/system
- Krkr2Compat
- KAGEX3/system
- All script files of a complete game / 一部游戏的全部脚本资源
The complete game has been runtime-verified to launch and run correctly using only decompiled scripts.
游戏测试项目已通过运行时验证，仅使用反编译脚本即可正常启动并运行。
