Emulation of the SNES is now available on handheld units, such as Android devices, Apple's iPhone and iPad, Sony's PlayStation Portable (PSP), the Nintendo DS and Game Boy Advance, the Gizmondo, the Dingoo and the GP2X by GamePark Holdings, as well as PDAs. While individual games have been included with emulators on some GameCube discs, Nintendo's Virtual Console service for the Wii marks the introduction of officially sanctioned general SNES emulation, though SNES9x GX, a port of SNES9x, has been made for the Wii.
