*Circus Caper, known as Moeru! Onīsan (燃える！お兄さん, lit. "Burn! Older Brother") in Japan, is the title of a side-scrolling Nintendo Entertainment System video game where the player controls a young boy on a quest to save his sister who has been kidnapped by the circus. The game was released in 1990 by Toho and received poor reviews.
The USA version has a number of changes from the Japanese versions. Mainly minigame and RPG elements were removed, the stages were modified and the setting was changed to a circus. The Japanese version also features several credits screens at the end which were removed from the USA version, probably because the USA staff did not have Japanese knowledge to translate them. The soundtracks also differentiate (for the most part). In the Japanese version, instead of weapons, your character shouted quote bubbles and the stages are in a different order.
