Engadget guide explains how to connect GameCube to modern TVs

The guide explains that the GameCube was designed for analog CRT TVs, which lack the analog inputs used by modern LCD and OLED televisions. To simplify the connection, the model of the console is the most important factor. The earlier DOL-001 model includes a Digital AV Out port, originally intended for component video cables, while the later DOL-101 variant omits that port. Users can identify their model by checking the back of the console for a Digital AV Out label or by reading the model number on the bottom.

For DOL-001 owners, the guide recommends the Retro-Bit Prism HD Adapter, which plugs into the Digital AV Out port and connects to a TV via HDMI. The adapter uses open-source GC Video software and features a USB-C port for easy firmware updates. Alternative adapters include the Carby from Insurrection Industries and a more affordable option from Bitfunx. To get the best image quality, users may need to hold the B button on the controller during game startup to enable progressive scan mode for compatible games.

For DOL-101 owners, the guide suggests using a RetroTINK-2X Mini, which converts the analog composite signal to digital HDMI. RetroTINK also sells more expensive upscalers that are only worth the cost for those with a large collection of retro consoles.

The guide also mentions emulation as an alternative. A Nintendo Switch 2 with a $50-per-year Expansion Pack subscription to Nintendo Switch Online provides access to a selection of emulated GameCube games, output at 900p for a sharper image on modern TVs.
