Ingame SM anabel is exactly the same that RSE anabel (but older), the great problem between games and this manga is hidenori insist to put all in one universe (see ORAS arc, he really put damage control towards archie and maxie), but games already jumps between at least 2 parallel universes and became painfully obvious in USUM postgame.
PS: one of the big mysteries is if RSE anabel cross-isekai'd with DPPt looker, who ended in ORAS resort instead of alola, when the other looker are currently, the one who isn't affected by ultraradiation (or looker whereabouts in general)
