Do n64 and GameCube have the same hook up cables?

No, the Nintendo 64 (N64) and GameCube do not use the same hookup cables. The N64 typically uses an AV cable with composite outputs (yellow for video, red and white for audio), while the GameCube can use a similar composite cable but also has options for component video and special digital AV output cables. This difference in connectors means that the cables are not interchangeable between the two consoles.
