Ha ha ha. Yeah, its a heavy grinding game, personally I always loved that part in a weird way: getting all the rupees to buy everything I can before I get to a temple, grinding materials to get that cool transmog /armor/title or grinding blobs and rats so that the next encounter I feel like a hammer instead of a stick ha ha ha.
The port is cooking great (in my opinion) we are adding all the goodies from the deluxe version which is always nice to have as bonus material in a game, and there are no slowdowns! That is going the best way to play this bad boy, but hopefully when the time comes to revisit the game and have some more grind, your Analogue Pocket will serve well with the update, which brings me to the answer:
Yes, the current download contains the .pocket file and the update will have it as well :)
Have a glorious weekend!
