*HLE (High Level Emulation): HLE works by using a DSP engine created by the developers from studying the real DSP. It is not perfect, and is notorious for causing garbled sounds, choppy audio, and skipped instrumentation. But DSP HLE is very fast, with almost no overhead, and it comes with Dolphin; no additional files are needed. | *HLE (High Level Emulation): HLE works by using a DSP engine created by the developers from studying the real DSP.

*LLE (Low Level Emulation): LLE uses DSP files dumped from a Wii to perfectly emulate the DSP's hardware behavior. This unfortunately requires a lot more processing power, but provides for perfect sound in nearly all games. The DSP files required for DSP LLE cannot be bundled with Dolphin, and have to be dumped by each user from their own | *LLE (Low Level Emulation): LLE uses DSP files dumped from a Wii to perfectly emulate the DSP's hardware behavior.

Download DSPSpy | Download DSPSpy and extract the files. Then, rename "DSPSpy_wii_dump_roms.dol" to "boot.dol" and place it in a folder in your apps folder on your SD card. Run the program on your Wii, and two files will be created: "dsp_rom.bin" (8Kb) and "dsp_coef.bin"(4Kb). Move these files into your Dolphin's "./Sys/GC" folder, and Dolphin will now be able to run with either of the two DSP LLE options. | ||
