Multicarts are distinct from minigame series such as Mario Party, Game & Watch Gallery, or WarioWare.
In contrast to this, the NES multicart Super Mario Bros./Duck Hunt contains two full-version games, each of which were available for purchase individually.
As storage capacity on cartridges continues to grow and become less expensive, the popularity of multicarts has seen a resurgence on the only remaining cartridge-based systems, those of Nintendo’s Game Boy Advance and DS.
Since launch, these systems have seen an increase in the number of “2-in-1” and “3-in-1” games, with some re-releasing popular titles previously seen on the same platform such as Konami's Castlevania.
The games are usually first-generation Famicom titles, several of which were never officially released outside of Japan, and in typical pirate fashion have either had their names deliberately misspelled, their copyright notices/logos removed, or both.
