[ozling]

hey i was wondering is the a guide for the save editor to tell you about the flags and their meaning or you just kind have to play around with it and go from their??

The Wiki on github have some information, but it is not always clear. No one's written a manual for it, but given the frequency of updates and additions, one needs to be updating the manual almost daily.

oh ok thanks ill try to find the link just to get an idea to know what I'm tempering with

Hi, I don't know if this is the right place to ask, I hope so.

I'm trying to use my custom cheat file (pasting the cheats I like, not doing my own) Since yesterday when I add an remove some cheats in the file, if I try to open cheats ingame it freezes and send error in nx-ovlloader folder.
I've gone to cheat updater app, update file (now it only shows teleportation cheat) and with that file does't freeze. But if I edit that same file adding my cheats, it freezes again.

Can anyone please tell me what is wrong with this file? I have 0 knowledge on coding. I'm using Atmosphere.
Thank you so much.

Well the one thing I know for sure will break your codes is the furniture code you put in here and that you just copy pasted you can't have the *AMS only part in there. Remove that and it should all work.

[garzacorporations]

Yeah, I(as player 2) was able to progress the island without relying on player 1 to initiate dialogue with tom nook and I also was able to build bridge, invite villagers, donate items for homes 3-5, etc for progressing island.

So, do you copied all flags or there is any one in particular that would make the trick?

Daaaamn, i need a good phone to use the joy con app and summon the amiibos XD

Hi, I've been editing the file removing one cheat by one (since removing *ams doesn't seems to work) and the issue was the "top down view" cheat, I think it conflicts with the "walk through walls" one.
Thanks again!

Unfortunately this did not work either on SX OS...does anyone happen to have a code that can replace pocket items with the rare hybrid flowers? Would make planting these much easier and faster than just inserting them one-by-one .

Dont use codes that set inventory items only using the first 4 bytes, because in this case, your hybrid flowers wont have the correct genetics

 

[catlady77]

so only 8 bytes can breed?

Why not using nhse or chetaslips codes for hybrids?

cheatslips has 4 byte codes so theyre also incorrect all i have to do is change to 8 byte

Force NPC spawns
This technique was shared by an anon on 4chan in the animal crossing general earlier today and as far as I know it hasn't been posted here yet.
1. Open your save file in NHSE and under the Map tab click on Edit Map... and select edit visitors
2. Expand both VisitorNPC and InitSchedule
3. Select the ... button in the top right corner of the Array
View attachment 210272
4. In the Members column delete every single NPC by selecting them and using the Remove button
5. 0 represents sunday and 6 represents saturday. Now you can add the visitors you want to each day of the week.
6. Repeat the process for InitSchedule, deleting every single NPC and readding them so that it matches the VisitorNPC schedule
7. Reload your game and now your desired NPC will spawn

Do you know, is there a reason Celeste isn't on this list of NPCs?

Why not using nhse or chetaslips codes for hybrids?

Because item id is in the first 4 bytes, and the genetics of the flower is on the second 4 bytes. Use something like this: https://gbatemp.net/threads/animal-...-bugs-etc-thread.560199/page-201#post-9032646

But overall, avoid using 4 bytes cheats (starts with 041) that put items on the invetory, they must be 8 bytes

--------------------- MERGED ---------------------------

so only 8 bytes can breed?

Suppose you have the pink colorful fishing road:

00002118
00000003

And you copy only 4 bytes to get the blue rose (0F24), you will end up with this:

00000F24
00000003

03 will be the genetics (2-0-0-0) (but it was the pink color of the colorful fishing road) and thats an invalid genetic for a blue rose, the only valid genotype is 3F for a blue rose (2-2-2-0) https://docs.google.com/spreadsheet...lview?pru=AAABcimo0HY*eZ7SI1Auz5FW262KgDkAIA#

if i try and catalog japanese only items will it glitch and not be able to pick up?

Wow thank you for the information and the link to having all 4 byte flowers in inventory. Do you know if this cheat you referenced would still work on the latest version 1.2.1? or would it have to be updated?

[DrakanShadow]

So, do you copied all flags or there is any one in particular that would make the trick?

I copied all the flags. from "player 1" to "player 2" and did not uncheck any flags "player 2" had and "player 1" didn't.
Only thing to note is when you go to build the first bridge, Tom Nook will give each player a bridge kit.
I also kept a list of all the flags I changed in case anything in game broke but had nothing of the sort happen.

--------------------- MERGED ---------------------------

I don't believe you can reorder the items. Though someone could correct me if I am wrong. Also you have no worry about the items glitching.
