ROM Hack Animal Crossing: New Horizons duplicate mail

[xgorinx]

Tried using NHSE to modify my save a few weeks ago, and didn't notice the issue right away, but every time I open the mailbox, I will just have one letter duplicated 300 times, and it erases whatever else was in there, so I can't get more than one letter at a time. When I used NHSE, the things I edited were received items, DIY recipes, some of the achievement flags, and the catchphrases for villagers. I don't have the original file before the edits, so I can't restore it. Looking for ideas as to what I could fiddle with in NHSE to correct this?

This thread can be closed. Ninji fixed it

Hi, I'm running into this same issue on my save file, what was done to resolve it?

If needed, my save file is also at easyupload, but with the url 277mgq (New member, so can't post links. Sorry. =( )

I think what he used to fix this was a blank postbox.dat and postboxHeader.dat file from what he told me. The only problem is getting it...

Interesting. I have another player on my save file, I wonder if I can just steal their postbox and use it as my own. Or even better yet, just use ones from an older save file perhaps. Not sure if mixing and matching will cause any trouble


That being said, if anyone has blank postbox files, I'm more than happy to grab them

Thanks for the reply. This left us both pretty bummed tonight!

Well, Ninji fixed mine by giving me a blank postbox / postbox header file after I gave him my file. This is the file he gave me: https://easyupload.io/8vfijr. Not sure if it's linked to my profile though, or HOW it was made. But maybe this will help?

Hi all, just an update on my situation.

xgorinx: I tried your blank mailbox, but it just caused my game to tell me that my save data was corrupted and wanted to erase it. Hard no on that (not that I didn't have a backup anyways,) but it means that the postboxes that you sent me really were tied to your user somehow

Klavice Gavin: Like I said before, I used a postbox and postboxHeader from an older save file, and it worked!!! I lost a few letters (just some songs and probably a Gulliver trophy) but that's small fry to ensure that my mailbox can just work for me. I keep regular backups, thankfully, so I had this data available

So for the record (and anyone googling this in the future,) here's what was edited:

Villager 5 (Bob) had his catchphrase replaced from his original 'pthhhbth' or whatever it is to 'ay lmao' because I thought that would be hilarious
Villager 6 was Yuka and was replaced with Audie. We copied all of her data wholesale, including personality, catchphrase, etc. (Her house is still a bit odd, but not too concerned about it) So Species, Variant, Personality, and Catchphrase were all changed here
Villager 8 was marked as 'moving out' so that we could replace her with someone more interesting via amiibo

Player 1 was given a pile of money and tickets and a stack of each fruit
Player 2 was given a pile of money and tickets and a set of golden tools

My guess is that one of the Villager edits didn't play nice with the version of the NHSE I was using (build was from 2020-04-25,) and didn't set all of the data properly for one of them (I'd guess V6, but I can't say.) So that when that villager sent me a letter out of the blue, it tried to access something, like a catchphrase, in the game data, was unable to parse whatever it found, and then blew up, and sent me 300 letters.

The letters were all favorite'd automatically, unopened, has presents attached, and had no text in the little preview blurb. Whenever I tried to open one of these letters, the game would just crash on me. I'm not sure if the 300 letters and the crashing are directly related, since I've seen other users that get 300 letters, but they're not actively crashing the machine (or actually contain valid presents.)

Here's my save file for fixing: https://easyupload.io/7zxt9m

I'll try an older save file and that file, but I doubt it will work since I used to SE as soon as it came out.

I feel bad I didn't keep multiple backups, but the earliest backup I have is from 3/29.

Edit: It worked. Thank you Ninji if it was you who did this, I tried one from an older save and that one OP posted, either way it worked!

I think this needs to be added to the FAQ in the main hacking post in case more people fall victim to this.

Can anyone help me too? I'm so sad.

Hi, the solution was to copy in an older version of the postbox.dat and postboxHeader.dat files into the villager folder from a saved, unmodified backup. It has to be YOUR postbox.dat and postboxHeader.dat, otherwise the game will freak out and think the data is corrupted. Good luck!

So I didn't have a backup available with a un-bugged mailbox...

I started a brand new game and played through the tutorial to generate a new postbox.dat and postboxheader.dat.

I then copied these across to replace the bugged files on my main save, and I was able to launch without issues.
When I checked the mailbox I had the two mails from Nintendo from the tutorial save.

I will confirm upon checking tomorrow's post if this resolved the issue.

Some notes:
-As a precaution I named the character and island the same as my main save, and used the same gender.
-I used the same yuzu install, same acnh .nsp and had the same dlc and updates installed (1.3).
