This is a warning to those who inject dumps- if you invite somebody from an island to move into an empty plot before dumping the data into the villager slot, it will give you the WRONG exterior for the house.

I tried to inject the dump into an empty slot with one empty "for sale" land plot available in-game, but it gave me an active villager with no house or physical presence. Tom gave me a moving kit that will give you an error that says "there's not enough space", regardless of how much space you give the kit to plot a house.

This function is extremely broken.

I'm using build #20200331.2 for NHSE

Its possible but it's not really recommended, and if you already are the type of person that separates yourself from the people who are hacking, Im going to go out on a limb and say that you're a high risk for accidentally ending up banned. I don't mean that offensively, you just really have to know what you are doing if you don't want to accidentally end up banned. Its safer just to keep hacked Switches off of Nintendo's servers, and locally swapping data over to a clean Switch.





So, can't I just use emunand then? Edit my save and bring it back to sysnand?

Okay guys. Special request. The Youtuber boundary break is asking me if it's possible to make an unlocked 360 camera outside similar to how it works inside your house. He's planning on making a boundary break episode soon but needs a code that will allow this. Anyone know if it's possible? I'm not super into messing with codes. I only made a no clip code couple weeks ago and he's asking for my help. Maybe someone more skilled can help me out with this situation.

Okay so Shesez is dead serious about wanting this 360 camera mod. If anyone can make one, I'll shoot it over to him via DMs with credits to whoever made it or contributed because he REALLY wants one for an upcoming ACNH video.

What's the link to the latest version of NHSE? Everytime he does a push of the files, it's a pain to find the new branch.
Thanks in advance.

So Im chipping away at finding a way to force villagers to the mystery island. The way the game stores values for villagers is a bit weird though. I locked down the address that determines what type of Animal will load in, but the value for which specific animal is not stored anywhere around there (or if it is, it doesnt use the same ID values that we do have)

Edit: i figured it out. It turns out that the specific animal ID isnt the same. So 04, 05 is really 04, 35 and so on. Im going to keep plugging away and with a little luck I should have a cheat to spawn specific villagers on mystery island negating any problems we have with the Save editor (for now) and the lengthy wait times for amiibo villagers!

if i remember correctly someone in here said putting bugs/fish in your inventory with the inventory hack doesnt put them in your critterpedia right? or did i remember something wrong. just trying to get confirmation before trying this out.

Correct, adding them with cheats will not add them to your critterpedia.

So the ACNH design pattern editor tool by FluffyFishGames works great and even losslessly converts .acnl files saved from acpatterns.com to the new data. It doesn't export them as .acnh or .nhd however so it's best to import .acnl files to your save and then use NHSE to export converted patterns to .nhd so that others can use them in the new format. Really wish support for Pro designs such as dresses would come out soon as I have some clothes designs that are in .acnl format that I'd like to import.

So, I've got a question, to those that are hacking this game. Are you able to play it online after you do? Connect to others players world and host other players?

I have a clean unpatched Switch, with a physical copy of Animal Crossing that I have been playing normally. My question is, if I decide to install custom firmware and cheat in the game to add certain items or edit miles, bells, etc. Will I be able to play online again with other people?

I do not recommend. Just know that everything is a risk. If you overwrite the file from Emunand to Sysnand, that's also a risk. If you don't get banned later, that's great. But if not, that's unfortunate for you. What I want to say is that if you don't know what you are doing, I don't recommend it at all like the person before has said to you.

  • TwoSpikedHands @ TwoSpikedHands:
    yall im torn... ive been hacking away at tales of phantasia GBA (the USA version) and have so many documents of reverse engineering i've done
  • TwoSpikedHands @ TwoSpikedHands:
    I just found out that the EU version is better in literally every way, better sound quality, better lighting, and there's even a patch someone made to make the text look nicer
  • TwoSpikedHands @ TwoSpikedHands:
    Do I restart now using what i've learned on the EU version since it's a better overall experience? or do I continue with the US version since that is what ive been using, and if someone decides to play my hack, it would most likely be that version?
  • Sicklyboy @ Sicklyboy:
    @TwoSpikedHands, I'll preface this with the fact that I know nothing about the game, but, I think it depends on what your goals are. Are you trying to make a definitive version of the game? You may want to refocus your efforts on the EU version then. Or, are you trying to make a better US version? In which case, the only way to make a better US version is to keep on plugging away at that one ;)
  • Sicklyboy @ Sicklyboy:
    I'm not familiar with the technicalities of the differences between the two versions, but I'm wondering if at least some of those differences are things that you could port over to the US version in your patch without having to include copyrighted assets from the EU version
  • TwoSpikedHands @ TwoSpikedHands:
    @Sicklyboy I am wanting to fully change the game and bend it to my will lol. I would like to eventually have the ability to add more characters, enemies, even have a completely different story if i wanted. I already have the ability to change the tilemaps in the US version, so I can basically make my own map and warp to it in game - so I'm pretty far into it!
  • TwoSpikedHands @ TwoSpikedHands:
    I really would like to make a hack that I would enjoy playing, and maybe other people would too. swapping to the EU version would also mean my US friends could not legally play it
  • TwoSpikedHands @ TwoSpikedHands:
    I am definitely considering porting over some of the EU features without using the actual ROM itself, tbh that would probably be the best way to go about it... but i'm sad that the voice acting is so.... not good on the US version. May not be a way around that though
  • TwoSpikedHands @ TwoSpikedHands:
    I appreciate the insight!
  • The Real Jdbye @ The Real Jdbye:
    @TwoSpikedHands just switch, all the knowledge you learned still applies and most of the code and assets should be the same anyway
  • The Real Jdbye @ The Real Jdbye:
    and realistically they wouldn't

    be able to play it legally anyway since they need a ROM and they probably don't have the means to dump it themselves
  • The Real Jdbye @ The Real Jdbye:
    why the shit does the shitbox randomly insert newlines in my messages

    It does that when I edit a post.

    It inserts a newline in a random spot.

    do y'all think having an sd card that has a write speed of 700kb/s is a bad idea?
    trying to restore emunand rn but it's taking ages... (also when I finished the first time hekate decided to delete all my fucking files :wacko:)
  • The Real Jdbye @ The Real Jdbye:
    @Karma177 that sd card is 100% faulty so yes, its a bad idea
  • The Real Jdbye @ The Real Jdbye:
    even the slowest non-sdhc sd cards are a few MB/s
  • Karma177 @ Karma177:
    @The Real Jdbye it hasn't given me any error trying to write things on it so I don't really think it's faulty (pasted 40/50gb+ folders and no write errors)
  • DinohScene @ DinohScene:
    run h2testw on it

    when SD cards/microSD write speeds drop below a meg a sec, they're usually on the verge of dying
