ROM Hack [Spider] Animal Crossing: New Leaf RAM Editing Thread

[PikaStitch]

I've been analyzing several RAM dumps and I thought I should share my findings:

The byte at offset 0x49526 corresponds with the size of your town tree. If you change the byte's value, the tree's size will update to reflect your change, but it will revert to what it should be next time you load the game. I'm fairly certain this is because it cross-references the values stored at offset 0x5C730 and 0x5C7BA when you load the game. 0x5C730 logs your total playtime (in seconds), and 0x5C7BA keeps track of how many days you've played.

In my RAM dump of my test town, there are 2 bytes from offset 0x5C730-0x5C731: 3B B6. Reversing the order (this has something to do with endianness if I'm not mistaken) of the bytes and then converting them to decimal leaves me with 46651 seconds. At offset 0x5C7BA is the byte 1F which is 31 in decimal. So I've played 31 days with nearly 13 hours of playtime. You need to have played 500 days and have 500 hours of playtime for a fully grown tree. Knowing that, I converted 1800000 (500 hours in seconds) to hex, reversed the order, and came up with 40 77 1B. I did the same for the days: converted 500 to hex, reversed the order, and came up with F4 01. I replaced the bytes from 0x5C730-0x5C732 with 40 77 1B, and the bytes from 0x5C7BA-0x5C7BB with F4 01. I then injected my edited RAM dump, and reloaded my game. The result:

(I time traveled to summer to take this screenshot)

Now, remember what I said about offset 0x49526? As you might've guessed, you don't have to change it at all. It will adjust itself to be in accordance with the values found at offset 0x5C730 and 0x5C7BA after saving, quitting, and reloading. For what it's worth, the byte at offset 0x49526 is 07 when fully grown, and 00 when at its smallest (00 also appears as a sapling for the duration of the first day in a newly created town).

I'm still pretty new to hex editing, so sorry if I didn't explain it well, or if I missed something.

I can back up this and say I got the exact result DON'T INJECT FROM INSIDE A BUILDING I did a few tests and every time I injected from a building I would get a crash data + my town would go into fall wheather mode, so inject outside.

I'm making a list of all of the values of house exteriors. I ignored the non arched doors as the type of door is determined by editing a byte in hex, so there are only arched versions listed.

aaand here it is. The bytes for house exteriors and such. I think it's all correct.

Hey, just wondering if it be possible to force club lol to open via hex editing? I got the signatures, gave the sheet to shrunk, waited around a week for it to be built. But it never happened. It's been almost a month. I had no trouble with club lol on my last town. I've looked at other threads, nothing worked. I know main street upgrades haven't been fully figured out yet. Figured it'd be worth it to ask.

tldr; club lol hasn't opened after 2 months. do we yet know how to force it to open?

Hmmm...did you hack your game before building it? Oh and did you use the pwp unlocking qr code?

 

[regigiygas]

anyone know how to modify your bank account?

i dont want to max it out but i'm also too lazy to place bags & manually put them in there, lmao

Leaftools has a qr code for that

 

[regigiygas]

leaftools has a qr for filling your open slots in your locker with 99k bell bags.
which still requires that i put the into my bank account manually.


i'm looking to directly modify the amount of bells i have in my bank account.

If you have action replay knowledge, you can try making a cheat with ARCode

No, I started this town a month before the hacks came out. It should have been built long ago. I used the pwp unlocker, too. But club lol isn't supposed to be in the pwp list in the first place.

Hm. That's weird. Without Time traveling it should open in a minimum of five days. Try not Time traveling if you have been doing so frequently.

Oh they have one for the bank too. It's called bank breaker I think...I tried it and it works.

thats the thing tho, I don't want to be filthy stinking rich but I don't want to be dirt poor either


and I'm a lazy sack of trash so I don't want to put the bells in my account in-game
I want to go up to my ABD and just see like 10mil or something, yanno???

 

[kirekun]

I tested my theory. Here's a summary, for those who missed it: the game uses your hidden town ID to determine the colors of your town hall and station. 0x5C738-0x5C739 is just one instance of your town ID, it is also committed to memory at many other offsets. Changing one instance but not the others causes conflicts. (WARNING: when modifying the town ID, do NOT change both values to 00. Changing your town ID to 0000 bricks the game to the extent that even holding down ABXY won't bring up the prompt to format your data. Proceed with caution.) Here's what I did to test it:

Spoiler

I wrote a letter and saved it at the post office, then I made a pattern and saved it at Able Sisters. I then spoke to all my villagers. After that, I made a RAM dump:

My town ID is 1DB0. B0 = red station, so I changed it to 02 for a blue station. As I said in my original post, the town ID appears to always precede your town name. Just replacing all instances of 1DB0 with 1D02 (or worse, all instances of B0 with 02) would mean some unrelated bytes could get changed in the process. We don't want that, so I copied everything from 0x5C738 to 0x5C749 (the end of my town name):

I then replaced the bytes, like so:

The underlined byte is the only one I changed, but as I said, I did it this way to ensure no unrelated instances of 1DB0 would get changed in the process. 88 instances (the number of instances will vary from game to game) of 1DB0 followed by my town name were replaced.

I then injected the modified file. My station changed to blue, but more importantly: all of my villagers continued to recognize me (or rather, recognized that we had last spoken earlier that day), and I could send mail. As I thought would be the case, the game no longer recognized the letter I stored as being composed in my town, nor did it recognize the pattern I stored as being of my creation (although I could place them in my inventory, I couldn't send the letter or edit the pattern). The way to fix this would be by dumping the RAM after moving old letters/patterns into the inventory, and replacing the old ID (in my case, 1DB0) appended to them with the new ID (in my case, 1D02). It'd be a hassle to do each time, but at least it's possible.

With that being said, it should be safe to modify your town ID in order to change the color of your town hall/station, as long as you update all other instances of the ID as well. However, any stored mail or patterns you have will retain the old town ID, as it isn't part of the RAM we're dumping. Similarly, villagers who moved to someone else's town from yours would retain your old town ID (however, they should still recognize you as long as your character's ID and name are the same. They just wouldn't know their origin town was the same as yours, I think). There may be more scenarios like this, but for now, these are the only ones that have crossed my mind.

My apologies, as the following information is somewhat redundant. The colors of the town hall and station loop in this order:

Spoiler

Town Hall:
00 = Gray
01 = Brown
02 = Green
03 = Blue

Station:
00 = Red
01 = Green
02 = Blue
03 = Brown

If you take a given number mod 4, it'll always coincide with 0-3 according to that list (F9 mod 4 is 1, C2 mod 4 is 2, 0F mod 4 is 3, and so on). Of course, this is because as Wizardy said, it uses the two least significant bits of a byte to determine the color.

Do I get this correctly?
0x5C738 Contains the information about the town hall. Yours is in 1D so the color of your town hall would be Brown (0x1D mod 0x4 = 0x1)
0x5C739 Contains the information about the the train station.

--- In the back of my mind
{0x5C738,0x5C739} <= { Town Color , Station Color };
