Dolphin
Dolphin is a free and open-source video game console emulator for GameCube and Wii that runs on Windows, Linux, MacOS, and Android. It had its inaugural release in 2003 as freeware for Windows. Dolphin was the first GameCube emulator that could successfully run commercial games. After troubled development in the first years, Dolphin became free and open-source software and subsequently gained support for Wii emulation.
