+	DSP rec_v1
+
+	Tries to emulate a guesstimation of the aica dsp, by directly emitting x86 opcodes.
+
+	This was my first dsp implementation, as implemented for nullDC 1.0.3. 
+	
+	This was derived from a schematic I drew for the dsp, based on 
+	liberal interpretation of known specs, the saturn dsp, digital 
+	electronics assumptions, as well as "best-fitted" my typical 
+	test game suite.
+
+
+	Initiall code by skmp, now part of the reicast project.
+	See LICENSE & COPYRIGHT files further details
