King of Casino, available in both Japanese and US versions, is likely a casino-style simulation game. Players probably engaged in various casino games such as slots, poker, or blackjack. The US release suggests that the game was localized and thus likely features English language support.  NEC was the publisher for this game in both Japan and (likely through a subsidiary) the USA.
