The IPL’s sole purpose is to boot the system: it displays the iconic logo, checks for a disc, and then hands over all control to the game. Crucially, after booting, the IPL is not used. Nintendo provided all essential system libraries (like the AX library for audio or the GX library for graphics) on the game discs themselves. The console is, in effect, a "bare-metal" machine. The game carries its own operating system. The Wii extended this philosophy, including a more complex system menu (the Wii Channel interface) but still relying on games to provide their own runtime libraries for most low-level functions.
Use a homebrew application called or BrawlBox to create a NAND backup ( nand.bin ) of your console. Transfer the nand.bin file to your PC. bios wii dolphin exclusive
Dolphin is not the only emulator that supports BIOS files, but its implementation of Wii exclusive features sets it apart from other emulators.

For Dolphin, BIOS files are essential for emulating the Nintendo Wii, as they contain the necessary code for the console's boot process, audio and video processing, and other critical functions.
