Dolphin provides HLE for GameCube IPL (boot ROM), DSP, and Wii system functions.
|
|
No BIOS files are strictly required for most games. DSP ROMs (dsp_rom.bin + dsp_coef.bin)
|
|
are the most impactful optional files - Dolphin ships free replacements but real dumps
|
|
from hardware provide better audio accuracy in some titles.
|
|
ipl_regions: ["USA", "EUR", "JAP"]
|
|
dsp_rom_note: >
|
|
DSP ROMs are verified at load time via Adler32 hash.
|
|
Official Nintendo hashes: irom=0x66f334fe, drom=0xf3b93527.
|
|
Multiple free replacement versions exist (v0.1 through v0.4).
|
|
font_note: >
|
|
Fonts can come from three sources: real IPL dump (preferred), standalone font files
|
|
in Sys/GC/, or bundled free alternatives. The free fonts have different padding that
|
|
causes text positioning issues in some games.
|
|
nand_note: >
|
|
Wii NAND content (channels, saves, system menu) is managed by Dolphin internally.
|
|
Users can import a BootMii NAND backup (nand.bin + optional keys.bin) to populate it.
|
|
NAND import is only available in standalone mode, not via the libretro core.

Ishiiruka is a Dolphin fork focused on GPU performance (custom texture cache,
|
|
asynchronous shader compilation, post-processing). The BIOS/firmware handling
|
|
is identical to upstream Dolphin of the same era. No GBA link support (no mGBA
|
|
integration). No Realtek Bluetooth firmware support.

data_dir_note: >
|
|
Standalone builds use "ishiiruka" as DOLPHIN_DATA_DIR (CommonPaths.h:24,27),
|
|
but the libretro core overrides this to use "dolphin-emu" paths (Boot.cpp:46,49).
