// This is a test program for running code on the Wii DSP, with full control over input
|
|
// and automatic compare with output. VERY useful for figuring out what those little
|
|
// ops actually do.
|
|
// It's very unpolished though
|
|
// Use Dolphin's dsptool to generate a new dsp_code.h.

// Originally written by duddie and modified by FIRES. Then further modified by ector.
