Nintendo Mini Classics

Each Mini Classics unit is designed to resemble a miniaturized Game Boy.

Similar to the Game and Watch, the Nintendo Mini Classics units have alarm clock features.

Each unit is powered by two 11.6x4.2 mm button cell batteries (AG13/LR44/L1154/386/301/186), which are packaged with the Nintendo Mini Classic.

Some of the Mini Classics models, particularly the often-reissued Mario and Donkey Kong titles, have undergone several different color changes since the original 1998 releases, mostly due to multiple companies working with Nintendo to make and distribute the titles.

The companies that help distribute them are also responsible for the programming for their versions of the titles, which is why some might sound and behave differently.
