The Virtual Console is a library of games supplied by Nintendo and other providers and is accessible via the Wii U's eShop. It was originally provided on the Wii via one of its default available channels, the Wii Shop Channel, where Wii Points purchased through gift codes or ordered by credit card payment may be exchanged for Virtual Console and WiiWare games, in addition to a selection of add-on channels.
VideoGameCollectionHD uses the Virtual Console WADs downloaded through the homebrew software "WAD Manager" (released by the authors of MultiModManager) for its YouTube playthroughs of Nintendo 64 games available there to ensure accuracy, while using the multi-console Bizhawk emulator for all the adequately accurate running games on it that aren't on the Virtual Console, including Mario Party, Mario Party 3, the Pokémon Stadium games, Diddy Kong Racing, and the M-rated Conker's Bad Fur Day. VideoGamePhenom relies on the Virtual Console exclusively for its Nintendo 64 game playlists on YouTube, with all of its desired N64 games being available on the Wii Shop Channel (and all but Super Smash Bros., of all the user's uploaded games, being on the eShop as well). VGP uses Hauppauge HD PVR to record games done on the Virtual Console, whereas VGCHD uses the Elgato Game Capture HD.
The Wii Shop Channel, including its Virtual Console, is slated for closure in January 2019, following the discontinuation of Wii Points additions in March 2018.
