There's one person that's posted 3 times in this thread that they have 21-40 working. However when asked, they would rather keep it to themselves. You may see them bragging a few times so I urge you to just ignore them :)

Hopefully someone decent comes forward soon with the rest of the codes!

I just shared them.

I just got a chance to open up a 1.0.0 save, and here are the locations for the villagers who settle into the first three houses you build at Nook's request (so villagers 3, 4, and 5 that arrive to your island) -- at this point in my game they are merely "SOLD" signs on the houses, with their names underneath. So if you want to change those villagers before they officially move in, you can do so here:

Villager hex pairs are by SPECIES, VILLAGER ID -- so Tutu for instance has species bea07 and would therefore be "01 07" -- 01 to define she's a bear, 07 to tell the game it's the 7th bear (Tutu). E0 09 would be Sherb, 20 11 would be Marshal, and 12 10 would be Reneigh.


A NOTE ABOUT VILLAGER CODES:
In the cases of Villager IDs that go over 09 (for instance, Marshal is squ17 or Squirrel #17), you MUST manually convert them.

EXAMPLE:
Marshal is 20 11, NOT 20 17!
20 = Species ID (Squirrel)
11 = Squirrel #17, because hex counts up as 09, 0A, 0B -- not 09, 10, 11 -- so the 17 MUST be converted to hex, making the 17 actually an 11 -- because you would count it 00, 01, 02, 03, 04, 05, 06, 07, 08, 09, 0A, 0B, 0C, 0D, 0E, 0F, 10, 11 (<-- making this the "17th" number), and so on.

Same for Reneigh -- hrs16 -- 12 16 --> becomes 12 10 after conversion.

ADDITIONAL OFFSETS (Villager locations after they have moved in)
First Villager Offset Start
00000110 - 00000111
Second Villager Offset Start
00012BC0 - 00012BC1
Third Villager Offset Start
00025670 - 00025671

Ayy @patjenova can you do what you did for your DIY recipes to my fossil/insect/fish codes and basically condense it so we can just use one code to get of each so that its not just separate codes and just 2 codes for fossils,2 codes for insects and 2 codes for fish as your DIY recipes filled up all 40 slots of inventory? Would be much appreciated. I don't have much skill in doing it myself and tried and confused myself
 
https://pastebin.com/9U3zkbLD heres the bin to all 40 slots. its 1.1.0 though and needs to be updated to 1.1.1 its what ive been using and all works fine and since idk how to update code ill leave it here if anyone else knows how to lol
I have been told by several people (though not tested myself) that slot addresses are unchanged from 1.1.0 to 1.1.1. :)
 
I seem to have a problem with the blue rose plant

blue-rose plant, f24 [FlowerBud_03876]

The code is working for every item, but strangely, I can't seem to get the blue rose when the code is active... any ideas ?
 
the dupe is patched, Time travel is not.

have you seen "MyHorizons"?
This program can already edit the villagers internally

Could you reference this post with the list of DIY? I've been looking into @patjenova post but can't find it.

Thanks

edit: nvm I found It.. thanks

@Ultimos54 thank you. I'll try to do something like @patjenova did with the DIY list with the fossils, bugs, and fish. We still need to find a way to unlock all fish and bugs in the critterpedia. I had no luck with the hex editing. :(
 
yeah @Vapp13 to fix the encyclopedia bug only possible thing currently other then the Save editor that will come out is to get 2 saves where one has a fish/insect you haven't caught,then the other straight after catching it and then checking in a program to compare and see what changed.
Cheers for trying to do the DIY thing to my codes it is most appreciated.Will definitely give you a shout out when I update the folder :)

Legit just figured out that ever second line pertains to the item ID,so its just a matter of changing it to each individual ID. It is time consuming but if you do it,it would be awesome. If possible please do them in the order from my list as I did them in list order and it just makes sense LOL

anyone know who sky128956 is on cheatsdb? this guy legit just posted my codes without ANY shoutout/recognition/credit?

Some quick googling shows this person sucks at shooters, and tries botting, but gets banned from that, too. XD

There might be SkyQueen from the previous pages but idk if that's the same person.

In general, I don't really get people being proprietary about finding simple addresses -- that isn't unique work. Anyone that looks into it is also gonna find it. It doesn't make sense they wouldn't just credit you as the original person that compiled them.
 
I do find it rude when people don't credit others on here or don't quote them on gbatempt. Legit took me hours compiling that list LOL.Oh well not much I can do now. Man I wonder if the save editor is going to have a sort of map editor as well, would be a cool feature just building your entire island without having to make anything
