Console Compatibility
Ensure the adapter matches your specific GameCube model. Only DOL-001 models with a Digital Port support advanced adapters like Kaico or BITFUNX.

Resolution Support
Check if the adapter supports 480p or 1080p output. Some models scale to 720p/1080p while others keep original resolution.
