The Hyperkin HD Cable is plug and play, but like the description says it only supports Progressive Scan games only. While this is not an issue for the Wii it means that it only supports part of the gamecube library.
The L and R channels are inverted on my device, which is a big issue. While it may not appear to be noticeable in the menu and some games, it can be noticed in anything else. Because of a basic build quality error I am forced to give this one star.
