GGPO (short for Good Game Peace Out) is middleware designed to help create a near-lagless online experience for various emulated arcade games and fighting games. The program was created by Tony Cannon, co-founder of fighting game community site Shoryuken and the popular Evolution Championship Series.

History[edit]

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. As a reaction to its service, Cannon began development on GGPO and released the first ever version in late 2006. Cannon later demonstrated GGPO to Capcom, which was positively received.[1]

The downloadable GGPO client currently supports many games from Capcom and SNK including Super Street Fighter II Turbo, The King of Fighters 2002, and Metal Slug X through use of emulator. Video game companies have also implemented a licensed version of GGPO. Games using it include Skullgirls and Street Fighter III: 3rd Strike Online Edition.[2][3]

Tekken producer Katsuhiro Harada recently stated in an interview that GGPO is unlikely to be used for Soulcalibur V's online system due to networking and data reasons.[citation needed]

Design[edit]

Using a netcode technique called "rollback," GGPO puts lag ahead of a player's move which partially hides latency and creates a lagless illusion. The effects examine which players performed the right actions and correct any possible inaccuracies. The program itself can allow players to adjust latency in case of high ping situations; either creating a possibly jerky yet accurate representation or a smoother game with input delay.

GGPO client[edit]

The downloadable GGPO client itself has a matchmaking system for every game provided. Players can request challenges while others are able to spectate and chat. Once a challenge initiates, the match runs a ROM from emulator FinalBurn Alpha.
