saturn: the policy of the yabause team values backwards compatibility of savestates highly, so that there are a number of awkward things in savestating where certain variables are regenerated instead of being stored directly to keep compatibility. this has gotten to the point that if you, while paused, save slot 1, load slot 1, save slot 2, then the slot 1&2 saves will not be byte-identical. this commit fixes a certain case of that. i don't know whether this actually fixes any tangible user problems, though.
