Many thanks for writing. Some of the events you described also took place in other countries of the former Eastern Bloc. For example, these are Atari clones, sometimes called Rambo (since this character is often on the box). And when it comes to games with sprints, do you mean Game nad Watch clones produce by the Soviet company Elektronika? They were also popular in other countries of the region.

As for other consoles, maybe there is more information in some newspapers but unfortunately I don't have access to them. It's a pity because it's an interesting topic.
