Early models of the Wii are fully backwards compatible with GameCube software and most of its accessories; the Wii Family Edition and the Wii Mini iterations lack GameCube support. Early versions of the PlayStation 3 and all models of the Xbox 360 only offer partial support and use software emulation for backwards compatibility. Current versions of the PS3 do not offer PlayStation 2 compatibility, though PS1 compatibility is retained. Some models of the first generation of the PS3 offered full backwards compatibility for PS2 games. The Xbox 360's compatibility is increased through game-specific patches automatically downloaded from Xbox Live or downloaded and burned to a CD or DVD from the Xbox website and the PS3's compatibility is expanded with firmware updates.
