Anyways we need to wait and see if that calc is accepted in the first place, then get a CRT going for that.
Asides from that,
I found an interview with Aonuma on Majora's Mask and found an interesting explanation behind why the rupees stay in the bank.
"
Why is the bank vault in Clocktown not affected by time? Why is your money always the same when everything else resets?
Part of this is just the most practical answer. The bank needs to maintain your rupees, otherwise you would lose them at the end of every three day cycle, despite the fact that it's really important to build up enough money to buy things in the game. We needed to find some reason for stuff to stay in the game, and we considered the idea that there would be some kind of markings on Link's hand that maybe you could only see if you shone a black light on them. This was talked about, the identification of his account and the current balance in it.
This would sort of make sense in that world because every time he goes back to the beginning of that three day cycle, he goes back in time but he stays who he is, he retains everything that is part of his person. We thought that would kind of make sense, because you could just look at your hand and say, "Oh, yes, you were this person, with this account, and this is your balance." But that still would represent a situation where the amount of money in the vault was changing over time."
He also states bottles in zelda are pretty OP
"
Why are bottles so hard to find in the Zelda universe? Is there a shortage of glass?
As it turns out, in this remade version of Majora's Mask, we added one extra bottle. If you happen to collect all of them, you're going to see a slightly interesting event. It certainly is true that they were hard to find in the original games, and we wanted to address that by giving people more chances to find bottles by adding this extra one.
Regarding the bottles themselves being very valuable? I suppose it's true since they can hold so many different things it makes it possible for you to do more in the game. They do have a very precious existence, from that perspective. As to why there are so few, I would simply say it has to be that way based on how powerful they are in the game."
