As for dictionary definitions, from my experience don't expect them to be 100% complete or even correct for many definitions. For me, it is very easy to pick out one example. Look how the word Senescence is defined in multiple dictionaries:
http://dictionary.reference.com/search?r=2&q=senescence
Not a single mention that senescence in a cell biology context means that cells are no longer dividing or are in G0 of the cell cycle. Not a single mention of this - just a vague description of aging (cells that are in G0 and not dividing are not even necessarily aged - they can go into G0 in many other situations!). So much for the completeness or correctness of dictionaries...
You cannot therefore claim a vague dictionary definition, which does not even mention video games, is relevant. Try using sources from people in the emulation scene.
