Okay, everything worked installing Memu, but I can't find FEH. I look in the shop, can't find it, everything relating to FEH is there but its not showing up. FEH companion, FEH IV calculator, etc etc. just the actual game isnt in the store.
EDIT: It's not showing up in BlueStacks either
EDIT EDIT: I found it on BlueStacks and now it's saying that my device is not compatible with this version
