A simple fuzz framework I use to fuzz test ygocore yo-gi-oh card game.
Run ygocore.exe, you can get this game in the link below.

If you get a higher version program, you should change the VERSION parameter in extra_info.py.
Click the first button, which means play with others.
Then click the button top right to create a room.
Click the button '确定'. It will create a server thread in your local network with port==7911.
You should check your IP address, and change ygo_server_addr in leak_ygo.py.
Then just run leak_ygo.py
python3 leak_ygo.py
