Games using it include Skullgirls and Street Fighter III: 3rd Strike Online Edition. Video game companies have also implemented a licensed version of GGPO. The downloadable GGPO client supported many games from Capcom and SNK, including Super Street Fighter II Turbo, The King of Fighters 2002, and Metal Slug X through the use of a built-in emulator. Cannon later demonstrated GGPO to Capcom, which was positively received. As a reaction to its service, Cannon began development on GGPO and released the first version in late 2006. Before its creation, GGPO creator Tony Cannon was completely dissatisfied with the 2006 Xbox 360 re-release of Street Fighter II: Hyper Fighting after experiencing its criticized online capabilities.
