Debian-Ports PPC
Debian officially supported the 32bit Big-Endian PPC architecture from Debian 2.2 up until Debian 8, until the switch to 64bit Little-Endian PPC. Currently, Debian 8 PPC has been booted using Techflash's 4.5 kernel for the Wii. This distribution is broken and wont see any more development due to its age and lack of official support. ArchPOWER is the default and recomended distribution.
