At times different copies of the same game can work differently in the FC Twin. This may be explained by a malfunction with the cartridge itself. Some copies of Dragon Warrior or Super Mario Bros. 2 for example will not work in the FC Twin; while other copies of the same games will operate in the same machine. In other cases, the system simply does not function with certain expansion chips, such as those in Castlevania III: Dracula's Curse.
