用法

1. 下载依赖
   Python 3.7+ 注意，安装过程中，务必勾上 Add Python 3.8 to PATH 选项。
   tlg2png
   KrkrExtract
2. 解压游戏
   参见 KrkrExtract 的说明，解压游戏。
   务必勾选 Full Unpack。
   把 evimage.xp3 解压即可。
3. 解压游戏后在游戏目录会有 KrkrExtract_Output 的文件，在目录下新建 3rdparty 文件夹，将 tlg2png 全部文件放进去。
4. 下载该代码，放到目录下。
5. 在空白处 shift + 右键， 点上 “在此处打开 Powershell 窗口”， 运行

pip install pillow
python krkr_cg_extractor.py

enjoy~
