Oh, I know something about this. Some people that made this are part of DragonSector [1] polish hacking group that broke DRMs in trains quite recently [2]. Sadly I joined company after there were long gone. Really surprised seeing this posted here as it was pointed out, the repo is pretty old and archived.
