Backward compatibility

The Wii features backward compatibility with its predecessor, the GameCube, having the ability to run its discs and use its controllers and memory cards.
Later versions of the system from 2011 onwards removed the controller and memory card slots which effectively removed this ability, however the motherboard still has the pads for them and can be soldered back in with modification.

In telecommunications and computing, backward compatibility (or backwards compatibility) is a property of an operating system, software, real-world product, or technology that allows for interoperability with an older legacy system, or with input designed for such a system.

Modifying a system in a way that does not allow backward compatibility is sometimes called "breaking" backward compatibility.[1] Such breaking usually incurs various types of costs, such as switching cost.

A complementary concept is forward compatibility; a design that is forward-compatible usually has a roadmap for compatibility with future standards and products.[2]
