Changes

When the Nintendo Wii was launched, it introduced native backwards backward compatibility with the GameCube, allowing memory cards and GameCube controllers to be used with GameCube games. This is widely known, and it allowed Dolphin to support the Wii early in its open-source era. However, this compatibility was lost when Nintendo released newer models of the Wii called the Wii: Family Edition (although the ports were merely stripped from the casing; the circuit board still contains the areas where the connectors would go, see Wikipedia's section on it) and the Wii Mini, which also lacks an SD card slot as well. And on the Wii U, the GameCube connectors don't exist at all, only being offered afterwards afterward as a USB peripheral in order to play Super Smash Bros. for Wii U.

However, homebrew developer FIX94 has developed an interpreter that allows all versions of the Wii (and the Wii U) that can run homebrew to read and run GameCube games. And not only from a disc, but from SD cards and USB devices too. This comes with the added benefit that more controllers are supported past the normal GameCube ones, and it enables the Wii U to play GameCube games.
