Multicart

A multicart is a Game Pak containing several independent games, generally with some menu to switch among them and a mapper to choose one or the other.

Nintendo officially discouraged multicarts because of their "shovelware" cachet and association with piracy. Instead, developers were supposed to tie numerous play styles into one plot line (like in Battletoads for NES, Mario Party for Nintendo 64, and WarioWare for Game Boy Advance).

Most pirate multicarts have several NROM games because it's really easy to switch them, even in mappers as simple as GNROM or the Color Dreams board.
