you can add new cheats to vcmi in addition to vcmiglaurung, vcmieagles etc. etc.?
If you want then you could tell me how to do it?
Adding them via programming (extending VCMI code) is the only way for now
Imagine, do you know how I can do to add them?
Yes - check CGameHandler::handleCheatCode in CGameHandler.cpp file - it belongs to VCMI server
You can as well just suggest it on bug tracker as feature request. If cheat code would make sense then someone of contributors can add it.
