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