I'd say the first two quarters are fine.

The other two are more questionable, but unless they look and/or smell funky, I'd personally go ahead and eat them. Now, if you got gut offal on it, I would be very suspicious of it.

I'd had a deer that one hind quarter had gotten some funk on it and was discolored by the time I got to it. I cut out and tossed the funky-looking part and packaged the rest of that quarter. It was perfectly fine and tasted no different than the rest of the meat.
