:;Hagi: An [[Official emulators|official]] GameCube/Wii emulator developed by Nintendo European Research & Development (NERD). Hagi has been used primarily for re-releases [[Emulators on Switch|on the Switch]], such as ''Super Mario Sunshine'', ''Super Mario Galaxy'', ''Pikmin'', and ''Pikmin 2''.
;Compatibility layerNative:;vWii (Virtual Wii): vWii is the part of the Wii U's system for Wii mode[https://wiibrew.org/wiki/VWii]. Similar to [[PlayStation_5_emulators#Hardware_features_and_peripherals|PlayStation 5 backwards compatibility for PlayStation 4 (Pro)]] or [[Xbox_Series_X_and_Series_S#Hardware_features_and_peripherals|Xbox Series X|S backwards compatibility for Xbox One]].
==Hardware features and peripherals==
The Wii Optical Disc (RVL-006) is the physical game medium for the Wii, created by Panasonic. Nintendo extended its proprietary technology to use a full size 12 cm, 4.7/8.54 GB DVD-based disc, retaining the benefits of the GameCube Game Disc, and adding the standard capacity of a double-layer DVD-ROM. Wii Discs always include a partition with files to update the Wii system software, which are installed before starting the game if needed. This ensures that systems that cannot connect to the Internet are still updated. For the same reasons as the GameCube, the Wii cannot play DVD-Videos or CDs. However, earlier Wiis can play DVD-Video using [[Homebrew_and_hack_Roms|homebrew]] such as WiiMC.[https://en.wikipedia.org/wiki/Nintendo_optical_discs#Wii_Optical_Disc]
*Dolphin has support for Wii Optical Disc dumps/[[Save_disk_space_for_ISOs#GameCube_.2F_Wii|images]]. But unfortunately most regular optical drives for PCs are unable to read Gamecube & Wii discs, so you need to rip your discs. However you can use some out-of-print models of DVD drives which may read GC and Wii discs but even then you'll need a compatible software tool like Rawdump or Friidump to dump it. See [[Ripping_games]] page for more information. Other than that, there is no support for DVD-Video if you plan to use Dolphin with WiiMC [[Homebrew_and_hack_Roms|homebrew]] software for DVD-Video.
*Virtual Wii has support for Wii Optical Disc ([https://youtu.be/4iaq_mKn7mE demonstration]). It cannot play DVD-Videos though, but we don't know if it's possible to play DVD-Videos using Virtual Wii and [[Homebrew_and_hack_Roms|homebrew]] software (similar to earlier Wii models as mentioned above). According to some user reports it's possible with using external optical drive[https://gbatemp.net/threads/full-dvd-playback-on-wiiu-vwii-wiimc-lg-drive.500189/].
*See [[Home_Media_Player#Emulators|this dedicated page]] for more information about home media playback support for emulation softwares.
