Arcade Classics Series
The Arcade Classics Series is a North American marketing label for Nintendo Entertainment System ports of arcade games that were popular back in the 1980s. These games were released separately in Japan for the Family Computer but grouped as a series when released in North America in 1986. There are four ports belonging to Mario and Donkey Kong series of games. Unlike the arcade originals, these ports have two difficulty settings, A (beginner) and B (expert).
