Thanks, I'll give it a shot but the point was to somehow upload a custom image to the Save Editor so I could import it onto a banned switch...is this application able to do that? or can it convert the file to a .nhd so I can import it into the editor?
It actually loads your save and you can directly import images or .acnl files into the save of your banned switch.

Alright, here's a really niche find from my digging around: how to change Passport Registration Date (and subsequently also achievement dates for Nook Miles but I won't go into that here), for anyone who wants it. I was trying to find changing island fruit, but I fell asleep before I finished digging around.

Much like in New Leaf, the Registration Date is formatted inside the hex data as

YY YY MM DD

However, it should be noted that the Year value will be transposed inside the hex. What do I mean by this? I'll walk you through an example. Let's say your Registration Date is March 19, 2020. Inside the hex, that would be:

E4 07 03 13
YY YY MM DD


So, how do I get these numbers?:

Month of March = 03 (values listed below)
19th Day = 13 (values listed below)
2020 = 07 E4 (a decimal to hex converter will give you this value)

March 19 2020 therefore:
03 13 07 E4
MM DD YY YY


But wait, I said E4 07 just a second ago. Indeed. For the year values, specifically, you'll need to flip the digits after you calculate them via hex. Which means that 03 13 07 E4 becomes 03 13 E4 07 for March 19, 2020.

Leaving us with 03, 13, E4 07, or MM, DD, YY YY, and New Leaf requires a specific format: you'll just need to move the YY YY digits to the front so that your format is properly YY YY MM DD, or:

E4 07 03 13
YY YY MM DD


Registration Date Offset is 001D71F8 - 001D71FB

Finished first pass of my code generator, which @Ultimos54 removes the need for a full list of all villager cheats.

Tool: https://mpql.net/tools/acnh/codes/
Thread: https://gbatemp.net/threads/acnh-code-generator.561856/

This can generate item codes, with optional slots/button activators, and it can generate mystery island villager codes. Enjoy. :D
first of all, i just want to say thanks for this! but, ur generator says "Activate a villager code AFTER going to the mystery island." is this correct? so:
1. go to mystery island
2. talk to villager, invite
3. go home
4. activate code?

and does ur code work for 1.1.4?

If the code works the way I think it does, I suspect that you are supposed to
1. go to mystery island
2. activate code
3. talk to villager, invite
4. deactivate code/go home

ahh okay, ill try this on 1.1.4
When you are flying to the mystery island, the game clears the islander's id and replaces it with what should spawn so I'd hazard a guess that activating a code before flying to the mystery island is going to end in pain because you're telling the game to spawn a villager while the game goes NO U I WANT THIS VILLAGER.
But you can't activate it after you've gone home because by then your villager id has already been saved and you are too late to change it: the code affects what villager is on the island, not what happens after the villager becomes one with your plot of land.

What if you were to revert your Switch back to it's original NAND files? Would that remove all logs from using the hacked files or it doesn't matter as it's online base?
If you've never connected online after playing the game ever then the only thing you would need to do is completely delete your save file then the logs are gone for the game that would be sent to Nintendo.

If you have connected online then no it won't help you

little curious if anyone has knowledge on this. so with color variant furniture. does the number in the bottom row code mean the color itself or how many colors it has. so if a sofa has blue red green. does a specific number for all green variants equal the same code? or does the variant code just depend on how many variants of that furniture it has? would make it way easier for me to make a few lists of codes if i know if its based on amounts or colors of that piece of furniture.

For the life of me I can't get NHSE not to restart my save. Am I doing something wrong? Any change I make I boot the game and I get the beginning cutscene. Any help at all would be amazingggg. Want to map edit and bypass all of the lame terraforming restrictions.

I don't think you can yet. You would need to set each flag, in order, to simulate you progressing. lots of saving, editing, time jumping and restarting the game.
