DSPSpy: First version submitted, resurrected from the ages of time. Build the dsp code by running dspbuild.bat (or an equivalent shell script), then build the elf using devkitpro/libogc and boot it on your Wii using Homebrew Channel or whatever. You'll get a lot of numbers on your screen.

DSPTool: build fix.
