Found a way to export ghidra project as an XML, put this XML to base patch repo. It contains some variables/functions names and known structures (not 100% sure, that all correct, but anyway). I hope, it might be helpful, if someone will want to investigate/disassembly. I'm not a Ghidra expert, if there is a better format to share project - let me know).
