Nintendo has issued a complaint under the Digital Millennium Copyright Act against 'Super Mario 64 Online,' a hack of the original Nintendo 64 game that allowed several players to play the game together online.

The hack was created by Kaze Emanuar, a well-known Super Mario 64 modder who has previously created an unofficial sequel to the game called Last Impact, as well as a user-friendly Super Mario 64 level editor. Emanuar's mods are popular in the modding community and have previously gone viral for showing how far he could push the boundaries on a classic game that was originally released in 1996. The YouTube video for Super Mario 64 Online, for example, had 1.1 million views before YouTube took it down because of Nintendo's DMCA complaint.
