ROM Hack Animal Crossing: New Leaf Save Editor

[froggestspirit]

Hi, I actually talked about this a little in the RAM Editing Thread, and posted about my findings.

The grey box will persist even if you place a second bridge (I've tried it). I get the feeling that if we are able to edit the main-street acres, then perhaps the grey box would go away, because it could be caused by the museum-side? Just a theory. More likely, the game just isn't capable of having 2 beaches.

Fwiw, I believe the box in the sky is from being at a low elevation where you normally are not supposed to. It shouldnt have anything to do with main street. I first noticed it when i made a beach higher up to fit an island in below

That makes sense. Could you explain what you mean by making a beach higher up?

having the beach at a higher acre instead of the southernmost one
Also, you can make your island bigger. I made mine longer. the map was glitched, but it worked
I just tested normal town acres on the island. Glitchy for the map (and the hut is buired underground, you can still enter it) but it works! though 4x4 is limiting

Reposting this here in addition to the leaftools thread.

I have figured out how the save file checksum for most of the files in Animal Crossing: New Leaf's savedata works. For the most part, it's CRC32 with a custom polynomial.

(Garden.dat is pretty silly, in particular: )

Spoiler: garden.dat checksums

// Garden.dat checksums
// "@ofs: data_len;" means "checksum data_len bytes at ofs+4 and store the result at ofs."
@0x80: 0x1C
@0xA0: for (int i=0;i<4;i++){ @0xA0+0x9F10*i: 0x6B64; @0xA0+0x9F10*i+0x6B68: 0x33A4 }
@0x27CE0: 0x218B0
@0x495A0: 0x44B8
@0x4DA5C: 0x1E420
@0x6BE80: 0x20
@0x6BEA8: 0x13AF8

Does anyone have an exported savefile from savedatafiler containing "mvplayer.dat"? If so, I'd appreciate your sending me that file (and, really, your entire save) -- it'll help me make a save checksum fixer for ACNL so that people can hex edit their saves instead of doing RAM hacks. (I may eventually make a tool to edit the savedata, we'll see.)

Here's my actual checksum code: http://pastebin.com/NkWZQ37J

You can also lazily use HxD's custom CRC if you're into that thing:

Does the savefile contain any extra data that cant be modified with the ram dump?

Is this possible? So for example instead of having 5 acres vertically you can change your acres so that there are say only 3, and more acres of ocean?

The acre editor link is broken. Please update it!

 

[jacobsladders]

would it be possible to add the able sister's wallpaper and floor and the wallpaper and floor from town hall?

Yes, don't quote me on this, but it appears that making a map that "makes sense" will cause it to work. I'd advise not messing with the top borders though (except for maybe changing the side a beach is on. Mine has only a south beach, walls on left and right.)

@marc_max Please update this in the first post...
I've updated the map editor everyone, it now auto-generates borders (so no more hex-editing required), and now shows the way the water flows in rivers (and what side the waterfall is on, but hopefully that was easy to tell anyways). Report bugs to me

Hello, I wanted to know if it was possible that my 3DS passes between 9 and 9.5 for my console is 9.8 and I would have liked to have too hack version for my city ?

 

[AshleyKrystine]

I've been using the RAM editor for several weeks, and have never had a problem. Today, I dumped my file, and edited it. When I tried to inject it, my game crashed. I've tried injecting it multiple times since then, but it still keeps crashing. Any clue as to why?

9.8 is more than both 9 and 9.5, so no.

Talk to resetti first before injecting

 

[AshleyKrystine]

I have. After I inject, I get a green screen. Once I go back to my game, it freezes, the game crashes and my whole system restarts.

EDIT: I'm an idiot who forgot to rename my file back to acnlram.bin
It's working now!

It in no other way for Version 9.8?

 

[Danicraft203]

When are we going to be able to create islands in our towns?

 

[Luky2000]

I have my 3DS in 9.5-23 this is good ?

After giving the picture thing another shot, I figured it out. It's a lot more simple than I thought it'd be. Bad quality, but it's better than nothing.

I normally release my findings, but after thinking for a bit, I feel that releasing the method to the general public right now would be a bad move, as I have a feeling that people would put inappropriate pictures into their games and take them online for kids to see. Not really fond of ruining the experience for others, or possibly having a required update to connect to online. I enjoy handing out freebies to strangers, and don't want to have that ability taken away. I'm sure that someone will inevitably release it anyway, but please try to understand where I'm coming from.

If everyone who knows how to edit the TPC picture refuses to explain it, would anyone be willing to change it for me~? Here is what I wanted to change it to:

It'd be nice if someone could maybe even just pm me instructions of how to do it myself, so people with... vulgar intentions don't find out~ ^-^"
Also because I was also considering my profile picture on this website as my TPC photo, and have a tendency to chop and change things to absolute perfection, so would likely want to change it fairly often at first and wouldn't want to continually bother someone~
Oh, and I just realized that picture is in .png format, so I converted it to .jpg:

Unfortunately, that changed the background from transparent to black~... Q///w///Q
Oh well~... Oh, it'd also need to be cropped/resized, huh~...

 

[froggestspirit]

AFAIK, no. I'm not sure if there's a way with a dongle that can extract the saves now that the checksum has been figured out

 

[Luky2000]

I have another version of 9.5-23 3DS is that its going to work or is it just?

 

[BerserkLeon]

The last version browser-related hacks work on is 9.5-22, if I recall. 9.5-23 has the new browser version so it won't work.
