PS2 AV Cable Not Compatible With GameCube: Different Connectors & Signal Mismatch

No, a PS2 AV cable won't work on a Nintendo GameCube.

Why

• Different connectors: PS2 uses a proprietary multi‑out; GameCube uses a different multi‑AV port with unique pin layout
• Signal mismatch: PS2 outputs composite + stereo audio; GameCube supports composite, S‑Video, and stereo via different pin assignments

Solution

Buy a GameCube‑specific AV cable (composite, S‑Video, or component if your model supports it). Widely available online and at retro game retailers.
