Note: This article is not about running Mac Classic directly on the Wii (e.g., with modified drivers). Instead, Linux is used to run a program called Mac-on-Linux (https://www.maconlinux.net) that takes care of the hardware interfacing problem while utilizing the Wii's PowerPC CPU natively, as it is very similar to a Mac G3 series CPU. Still, it is an interesting accomplishment.
