193.96.224.42: bdx file format - which program writes it (2017-12-14 14:43) [#11058]

MultiGo says, it can read bdx files, but which program writes these files and - how do they look inside?

I found a hint:
BDX： 清风和弈城软件采用的棋谱文件
which translates (by google):
BDX: Breeze and Yi cheng software chess file

What software (weiqi) are these? ... asks RueLue
