Gekko

Gekko is an experimental GameCube emulator written entirely in C/C++ to make it as portable as possible. Its original core was written for x86 Windows systems and could boot many commercial games.

Work began in 2006, and the project was revived in 2012 with the aim of running natively on x64 systems and on other platforms such as Linux.

Development picked up again for a while but stopped once more in 2013, with no sign of activity from the team since. Before then, the team wrote a new video core that let games running in the interpreter reach nearly full speed and added dual-core support to video emulation. Like many other GameCube projects, however, Gekko never caught up with Dolphin.
