For the casual player who just wants to play Mario Galaxy at 4K, the standard Dolphin HLE mode is flawless. You do not need a BIOS.
However, if you are chasing exclusive accuracy—if you want to play Wii Sports Resort without motion control desyncs, or experience Metroid Prime Trilogy with the exact frame-timing of a real console—then the BIOS route is mandatory.
Emulation is about preservation. Dumping your Wii's BIOS ensures that even as original hardware turns to dust, the soul of the console—its boot chimes, its system menu, its unique low-level code—lives on inside Dolphin.
To use this feature, you must have legally dumped Wii system files.
Dolphin without the BIOS is a fast, sterile hypercar. Dolphin with the BIOS is a lovingly restored classic—quirks, boot chime, and all.

In the context of the Dolphin Emulator the Wii BIOS (firmware) is not required to run games, but it is necessary if you want to access the Wii System Menu or experience the original boot animation
. Unlike many other modern emulators, Dolphin can run Wii and GameCube titles using High-Level Emulation (HLE), which replaces the need for copyrighted system files. Key Insights for Wii "BIOS" in Dolphin Optional Requirement

The confusion surrounding "Wii BIOS" often stems from users attempting to run the Wii System Menu (the main Channel interface) or WiiWare/VC titles. These do require a dump of the Wii’s NAND flash, which contains the System Menu, IOS (internal operating system modules), and tickets. Some users mistakenly call this NAND dump a "BIOS."
Here lies the nuance: Even for the System Menu, Dolphin does not emulate a traditional BIOS. It emulates the Wii’s internal flash storage. The System Menu is just a piece of software that runs on the emulated hardware.

However, this is strictly for the optional Wii dashboard experience. For 99% of game playing (inserting a disc or loading a GameCube/Wii ISO), no NAND and no BIOS of any kind is needed.
No other major emulator has this luxury. You cannot boot a PlayStation 2 game in PCSX2 without a PS2 BIOS. You cannot boot a Saturn game in Yabause without a Saturn BIOS.
