i'm guessing you have the game on an sd card. the card is messing up. redownload to system memory. no alternate solution.

Except it doesn't seem to be the sd card. I've redownloaded to system memory twice, one time each with two functioning sd cards, and no results like them.

Edit: More info on my Switch setup. 128gb sd formatted to fat32, as exfat loads to black no matter what. Updated everything--just factory reset, reformatted sd card, and added latest sdsetup files. I guess we're just at a loss here. Firmware 9.2.0 might be the issue?

Edit 2: @TomNookNMT If you happen to not be on the latest firmware...I highly recommend copying the sigpatches from the "I heard that you guys need some sweet patches" thread to your sd card. It might solve your problem. It completely fixed mine!

Make it Rain
Credits to Ninji for publishing the datamine information and producing the tools that make this possible.
1. Upload main.dat and mainHeader.dat to Ninji's save editor https://wuffs.org/acnh/save
2. When it says Downloading the game data file... it has finished loading your game basically open up the data tree tab and double click SaveLand to expand it
View attachment 210269
3. According to Ninji's datamined bcsv https://wuffs.org/acnh/bcsv_120/html/WeatherPatternParam.html rain is between 10 and 15. Since idk what works, I just picked 13. Since idk what field we're editing I just slapped the 13 (rain) into both yesterday and today's weather pattern. And idk what cloud pattern we're supposed to use so just to wild mass guess I went through my other parameters for the mystery island tour weather and found like one 12 in the enum and a huge bunch of 0s. Since cloudy weather is probably less common than fine weather I expanded CloudPattern by double-clicking it and slapped 12 in every single enum under CloudPattern (by also expanding them)

Weather patterns seem to have been datamined by Alexis https://docs.google.com/spreadsheet...oKLntyfUF_e-B6WPRl8l-jM1o/edit#gid=1139529364 so yeah

4. Save the game and download main.dat. Since the site won't seem to generate mainHeader.dat you will need to slap main.dat on your existing save folder (overwriting your previous main.dat) and open the whole thing in NHSE and save the game again.
5. Load up the save file and previously the save file which predicted both sunny both today AND tomorrow thanks to television reports on tvs in ACNH at specific times is now raining. No guarantees this is perfect since idk what I'm doing but maybe you guys can test it out.

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

Totally worked, finally got Redd to show up. Only my 3rd time getting him... my rng sucks lol

Hey guys, just my contribution as I was searching on how to get color variants of streetlamps. Hope this helps (and works). I haven't done too much testing but so far my default was green. I was able to generate a white streetlamp.

Note: This will automatically place it in slot 1 of your inventory and will overwrite anything that's currently there as soon as you activate it. Feel free to throw in button combos for activation.

Code:

[Slot 1 Streetlamp Green]
08100000 AC4723D0 00000000 00000EE8

[Slot 1 Streetlamp Brown]
08100000 AC4723D0 00000001 00000EE8

[Slot 1 Streetlamp White]
08100000 AC4723D0 00000002 00000EE8

[Slot 1 Streetlamp Black]
08100000 AC4723D0 00000003 00000EE8

Hi, I was wondering if there were any spawning cheats for bugs!

i put the new id but nothing happen. Still no appering dont know why

That is odd. Just checking. Your cheat file should be named 9429FC5202937D7F.txt, and is located in your SD card as:

/atmospshere/contents/01006f8002326000/cheats/9429fc5202937d7f.txt

or

/sxos/titles/01006f8002326000/cheats/9429fc5202937d7f.txt

double checking the numbers, trying another way like cheats etc that's all that can be done

Did you right click the item and then click "set" again?

Xjackio · May 25, 2020

There are 2 things i think might cause it
1. Didnt set it again in the slot for nhse
2. The count isnt high enough, i couldnt get beach towels variants with 0- 10 until i got them by trading, just to discover number was 286

Use cheats with edizon + nhse to get color variantes easier

that's very unlikely since the highest a colour variant can be is FF (255)

Beach towel variants in hex are 00, 20, 40, 60, 80, A0 and C0.

I will take a photo for u to see, using edizon to spawn any variant, then saving and using nhse to check count number

No! you might be right

i just realised count is an unsigned int16
Does your beach towel have a custom design? If so, then you're right.

Gift wrapping is catered for in @MyShiLingStar version
Star fragment trees and anything else you can dream up is now doable with @FabioCapela version through custom csv
you can run both versions at the same time , spawn the Star Tree in FC and wrap with MySS
