Sorry for long wait x.x Busy work days.
FInally unlocked all 5 shops in WOL the natural way after 6+ hours.
Note in case info was needed and idk if it affects anything: I played with all DLCs installed.
--All 5 Shops from WoL (The shops that sell 4 items at a time)
--1 Gym
--2 Explorers
--10 Dojos
Sidenote: In another save thats 11.0.0, I tried hex editing to give my save all cores in max amounts, and it indeed added them BUT it also random unlocked some Spirits in the Gallery.
Sadly, unlike the WOL shops, unlocking all the cores naturally will take a looooong time. (The All Unlocked save in page 1 shows theres over 100+ @_@; )
