Im glad somebody is out there still looking too. Its nice to have somebody who can poke around and see what I missed instead of somebody poking me to tell me what they are missing

Gotta get that Raymond
So I guess if the ascii string is what determines the spawn it would greatly simplify things. I'll have to test my theory though.

I do think it's highly suspicious that it says "cat00)", "cat01*", "cat02+" That looks very promising. I think you probably got it. I can't test it anymore as you know, but if you need any help let me know and I can poke around too.

I think it works. But I'm really surprised they used those ascii codes rather than the hex codes, I wonder which came first the hex codes or the character codes
EDIT: raymond now owns the plot.

Aww thats no fair, you got to use Cheat Engine while I had to bang together rocks I miss Cheat Engine.

Congrats! Can you convert that into SXOS format? or tell me where to look so I can?

;_; I'm unfortunately too dumb to make codes! (the emu also can't use them and it always starts at a different location in the memory which is where you're supposed to find the pointer or something for the emulator. My theory is that the way people turn emulator codes into switch codes is to find the offset of the value we want from a known address in both the emulator and an existing cheatcode and somehow add or subtract that so you get the right address, but I'm afraid the cheat code thing has always gone a bit over my head)
Basically, I just went to a mystery island. Just like you said, we lookup the character that's present (which is Octavian ocp00)
I then searched that as a string in CE. But I guess if you don't have CE ocp00 in hex is 6f 63 70 30 30
so you could search that (or maybe you have to swap the endian-ness around again)
then I just went to a new mystery island and looked at the 46 something results for the emulator in cheatengine
And some of them had changed over to the new resident (since we went to a new island and thus have a new resident). I grabbed all those values and edited them into Raymond's cat23

You know how the cheat you had was like
[Force Raymond on Mystery Island]
04100000 3F9DBBBC 00000004 <--------------Species ID (for Cats)
04100000 3F9DBAAC 31746163<--------------Species ID #2 (for Cats)
04100000 3F9DBAB0 00000033 <--------------Villager ID (Villager ID for Raymond)

I *think* your cheat earlier is right
04100000 3F9DBAAC 31746163<--------------Species ID #2 (for Cats)

When I convert 31746163 into ascii, I get 1tac
Which is cat1 backwards, but we somehow want cat23 there

or maybe we want 2tac there (because maybe we can't fit a 5 character string into it)
and then 3 in the next spot

 

[Lionheartwolf]

1tac

Hmm. I don't think it's as easy as changing that address, because when I checked all cats were still 31746163 regardless to whether or not it was cat 00, cat01, or cat02. Maybe I was mistaken though, if I was wrong I suppose the correct cheat for Raymond would be:

32746163 instead of 31746163 but I never tested it, and that code is for a pretty dated version. If the addresses didn't move than the correct cheat would be

[Raymond Appears on Mystery Island]
04100000 3F9DBBBC 00000004
04100000 3F9DBAAC 32746163
04100000 3F9DBAB0 00000033

If somebody wants to test that out to let me know that would be great. Also remember he may not look like Raymond so don't assume because you can't see him that it's not him.

I did some testing to make sure
For example I wanted Audie and she's a wolf, wolves are species ID 22 from the github, I checked in the save editor that Audie is "wol12", 1low is the first part which comes out as 316C6F77, 2 is just 32, so all together it's:

04100000 3F9DBBBC 00000022 "Species ID"
04100000 3F9DBAAC 316C6F77 "Villager ID 1"
04100000 3F9DBAB0 00000032 "Villager ID 2"

I made codes for multiple different villagers and it works perfectly.

I think what I have is wrong, upon reflection because emu memory is probably different from actual switch memory, I think the same values are displayed in a bunch of a different places. I did see the structure you mentioned where jumping back -0x10C showed the villager id (maybe part of the 5 letter string that's the full villager id) you mentioned and found that modifying parts of that structure gave me different outcomes, but when I edited that Raymond that you saw, I just edited the whole string rather than first searching for the species id to narrow down things (and the species id itself wasn't edited) and then carefully editing in those particular places...

Anyway, things are weird. I guess we won't know unless people test em

EDIT: or maybe only that 5 character string itself determines the villager and the species id isn't really needed, that's another possibility
EDIT2: my Raymond moved in and seems to have the right interior/exterior despite the fact I did not change the species id

 

[XKlarity]

Oh ok, thanks. And by completely move in you mean out of boxes? Also does this replace the furniture as well as the exterior or just the exterior?

no, it's fine to have them move in they don't have to be out of boxes and yes it does give the correct exterior and interior

 

[putti]

x nvm
empty nhv works
my dumbass just forgot where the villager was

 

[LunaintheShadow]

The empty nhv works for me, following all of the steps from eskil. The only issue i'm having is finding the furniture for my villagers until we get more villager dumps(.nhv)

 

[Jouslyn]

A new update is available.

 

[johnma2]

The new BuildID for the update is A31F81D41E1039C5 and also the Bells/Miles cheats will need to be adjusted. However any cheats involving item amounts in inventory don't seem to be affected, so they're still good to use from the previous update along with item/DIY recipe codes, those are all still good too.

 

[defectiveshadow]

Can someone dump their terrain layout? I'd like to see some new designs.

it worked for me thanks.
I went to Mystery Island. I activated the code there (if you activate it before entering the airport, the game will fail). the next day, Raymond will be on his island with the right interior and exterior
note: disable the cheat before leaving Mystery Island.

tested in update 1.1.3a

 

[thecommondude]

A new update is available.

Seems like just a revision bump. Pushed a commit to NHSE to support 1.1.4

 

[ELY_M]

new BID for 1.1.4 is A31F81D41E1039C5

 

[Ultimos54]

thanks @ELY_M I updated the OP

 

[ImNotSkilled]

Do i need a hacked/cfw switch in order to do any type of exploiting or cheating in ACNH currently?

 

[Ultimos54]

you just answered your own question @ImNotSkilled
