This partial port to the BK-0011M was created by Evgeny Pashigorov and Pasha Sizykh. Their programming team, Flame Associated, almost finished this five year project. When the IBM PC became popular, Flame Associated didn't fix the remaining bugs or add any cutscenes to their port.
A Russian text about their project is available here.
