Network adapters
Network adapter solutions for GameCube that enable online connectivity and network-based homebrew features.
Overview
GameCube originally supported network connectivity through the official Broadband Adapter (BBA) and Modem Adapter. These adapters are now rare and expensive. Modern homebrew software like Swiss can emulate the Broadband Adapter, enabling various community-made network adapter solutions.
All modern network adapters require homebrew software (typically Swiss) to function. They emulate the original Broadband Adapter behavior through software.
