DSPSpy

DSPSpy is a homebrew tool for experimenting with the GameCube/Wii DSP. It can also be used to dump the DSP ROMs.

Building

DSPSpy is built using devkitPPC; see the devkitPro getting started page for more information. DSPSpy also requires DSPTool to be built.

First, run DSPTool to generate dsp_code.h, for instance from tests/dsp_test.ds. The following commands assume an x64 Windows setup running in the DSPSpy directory:

../../Binary/x64/DSPTool.exe -h dsp_code tests/dsp_test.ds

To use the ROM-dumping code, run this:

../../Binary/x64/DSPTool.exe -h dsp_code util/dump_roms.ds

DSPTool can also generate a header for multiple DSP programs at the same time. First, create a file (in this example, it was named file_list.txt) with the following contents:

tests/dsp_test.ds
tests/mul_test.ds
tests/neg_test.ds

Then run:

../../Binary/x64/DSPTool.exe -h dsp_code -m file_list.txt

After dsp_code.h has been generated, simply run make to generate dspspy_wii.dol, which can be loaded by normal means.

Dumping DSP ROMs

Build DSPSpy with util/dump_roms.ds. When launched, DSPSpy will automatically create files dsp_rom.bin and dsp_coef.bin on the SD card (only SD cards are supported); DSPSpy can be exited immediately afterwards.
