ROM Hack Animal Crossing: New Leaf Save Editor

[Ewin]

My dream bed is in x58 y22 but when I try to delete it I have a yelow screen

CTRL+F > 67005822

Replace for example "E5005822"
E5= Illuminated tree.
Just for example.

Hey, I'm pretty sure I downloaded the file correctly, since it works well on the terrain editor, but this pops up when I try to open it in the ram editor.

*edit* I'm wondering if this is the reason, but what I'm using is a Japanese physical copy of the game if that does anything

Yeah that's exactly what I'm talking about, rxTools emunand, not gateway emunand. You need a legitimate cartridge of ACNL, or a legitimate eShop version

legit cia worked. I moved my .3ds save over to the cia and I've been using it since. thanks!

marc_max can you please fix yellow cosmos? placing them makes them show up as furniture pieces. thanks so much.

With this RAM editor you can change one villager to another, as I know. For example: Wolfgang walking on my main street and 16-cycle isn't over for him, I can't get him from other mayor's town. If I change one of my ingame villager on Wolfgang, how it will affect on whole game? Can some problems occur? Or will Wolfgang just dissapear from main street without any issues? Thanks for your help!

You are placing the flowers that become accesories when you wear them. Place the real yellow cosmos (IIRC they are called sun cosmos).

Okay, after losing time with this thing I've discovered that house furniture is twice on RAM. The save we have been dumping until now contains that data, but the game doesn't update those values in real-time, they are only updated there when you save the game. That's why injecting someone's else town wasn't updating room furniture (but I repeat: the data for the original house furniture is in it)
It's possible to dump and inject that memory chunk, but it's a bit harder than I thought since there are a lot of useless/unknown data between rooms. Since I've been busy lately, I don't think I'll work on that in a near future.


Also, duke_srg and I are planning to update the RAM dumper/injector with a fileless debug text version that should help some users who are having problems. They will also use a new different format for the RAM dumps (basically, they will be smaller since we're dumping a lot of useless bytes right now) so the RAM editor will become incompatible with the older format.

When I search "67005822" in HxD HEX it tell me "can't find 67005822"
I changed my town map like the screenshot but the game is still freezing, I have some buildings located between y:10 and y:15 (the player 1 house and the classic train station) can this is the reason of freezing?

Is there any specific information you're missing about rooms? I've been toying with room modification last week and furniture is pretty much the only thing I haven't pinpointed so far. If you tell me the information is twice in the RAM, I probably could do something with it.

But yeah, when I figured out how to update room size, it only worked upon reloading the game as well. I'm not really surprised that furniture is apparently working this way too

I've tried to inject houses furnitures on the title screen, and even just before the town loading, it just doesn't work for some reasons...

edit: best friends data is not in the ram file dumped in the title screen

edit 2: we can edit villagers houses

1) You edit it on the ram file, no more help about that
2) Either you move them manually on the ram file, or you use marc's web ram editor to move them

thx, I have delete it but my game still freezing

 

[MasterLel]

Put a beach stair on the right side and see if it crashes
And make sure you haven't put nullbytes to remove it (00 00 00 00), you have to put F8 00 00 00

 

[Sc0tline]

I can play but the game freezes after a few seconds, can I give you my acnlram.bin so you can look at it ?

 

[MasterLel]

Try what I said, put a beach stair on the right side

edit: best friends data is not in the ram file dumped in the title screen

Explanation:
The game stores savegame in different files (flash ROM for retail, encrypted SD for digital):
garden.dat (what we've been dumping until now, it includes house furniture)
friend1.dat (player 1 data: house furniture, stored patterns and letters amongs other things)
friend[2-4].dat (the same for all four players)
exhibition.dat (StreetPass data)

After talking to Isabelle, the game loads up garden.dat completely into RAM (we will call it RAM savegame from now on). Then it loads some chunk of bytes from your friendX.dat files (stored pattern/letters are only loaded if you talk to the characters who manage them).
When playing, almost all savegame data (except house information) is modified in our RAM savegame.
All house modified information is modified in the address where friendX.dat was loaded.
When saving, some chunks of memory of the house data are copied over to our RAM savegame. Then the RAM savegame and all friendX.dat are saved into their respective files.
That's it, it explains why your room furniture edits injections failed.

Why does the house data is twice in RAM?
This is my theory: It's because playing as your character you can still go to the other players' houses. When you enter their houses, the furniture info is read from the RAM savegame. Since you can't edit other houses, they are safe.

Then, if my theory is correct, we may be able to edit all characters' houses that are not playing when dumping the RAM savegame. But I haven't tried it yet (anyone can confirm it?).


I'm not missing anything, since I have all addresses where everything is stored, I know where all rooms start (including museum rooms) and I managed to edit them perfectly. However, it would be tricky to make a perfect dump for that data, since they are scattered between a lot of unknown bytes.

I have put a beach stair (look the map) but I dont understand where can I found nullbytes in HxD

 

[MasterLel]

Alright thanks for your explanation Marc, I'll make a character then see if we can do that
