=== Is it true that the RSP has hardware MPEG-1 acceleration? Is it used by
'''Short answer:''' RSP has two couples of opcodes (<code>VMULQ</code>/<code>VMACQ</code> and <code>VRNDN</code>/<code>VRNDP</code>) that are meant to simplify implementation of a very small part of the MPEG-1 decoder (inverse quantization and oddification of IDCT coefficients). They are not used by Resident Evil 2 or any other commercial game though.
