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. git-svn-id: https://dolphin-emu.googlecode.com/svn/trunk@2995 8ced0084-cf51-0410-be5f-012b33b47a6e
