"Dragon Castle" game for USSR Arcade "Multitron" (1990-1991?)

[Ivan555]

Hello everyone!
I'm new to the forum and need expert help.
I've been searching for the "Dragon Castle" game for the Soviet Multitron arcade machine for five years now.
This machine was manufactured by the Vilnius Calculating Machine Plant in 1990-1991. It was a late modification of the Soviet TIA-MC machine, but featured a single board, interchangeable ROM cartridges (like the NEO-GEO), and reduced sound. This machine also featured the already discovered "SOS" and "Fisherman Cat." There was also a game called "Dragon Castle," about which nothing is known.
The Multitron had a smooth, light green case.

The only visual confirmation is an interview with the machine's creator, Mikhail Safyan, and a magazine clipping. https://anatomyofarcades.tilda.ws/michail_safian

On the left side with the houses is "Fisherman Cat," on the right screen of the machine is the sought-after game "Dragon Castle" (with trees, a forest, and a little man).

I'll also attach descriptions of the gameplay of "Dragon Castle" from eyewitnesses.

"Dragon Island is similar to The Little Humpbacked Horse, also a sidescroller with Pitfall-style missions, but we control Ivan on foot—the blond guy with the headband, apparently wearing a white Russian shirt, blue striped pants, and red boots. He wields a sword—for close-quarters combat like chopping off Gorynych's heads—and a bow. The long one knocks down birds and spiders, and has a jump and crouch. First, he walks through the forest. On the second screen, pine cones fall on him, birds drop apples, and spiders cast snowflakes. He reaches a cliff from which he must jump into a boat. He rows to an island, and along the way, other things rain down on him. On the island, he approaches a castle. A spider with a cross sits on the gate and casts snowflakes. He must shoot it down with his arrow in time. He passes through a castle with enemies, and at the end, the Dragon Gorynych spits fire at him across the screen like Bowser, and behind him stands the princess. He must jump over the fire and crouch, and upon reaching the Dragon, slash it with his sword.

Professional help is desperately needed!
