Can we transfer saves between systems? Or is there a save ID like in New Leaf?

 

[Frexxos]

Till now a backup of the saves are yet not possible. If its possible we will now. This games saves in a other way

JKSV and blawar's Tinfoil can backup the Animal Crossing save file.

backup, ok and what about resotore ? working ? or only backup ?

 

[Lacius]

backup, ok and what about resotore ? working ? or only backup ?

I haven't tried it.

Just tried it. It seems to work.

 

[Spzjulien]

Just tried it. It seems to work.

i think the good way to try is, backup save, launch the game, save the game, exit the game then try to backup the save ...

 

[DEMONDICE]

Ok, so backup and restore works. Now we just need to see what can actually be edited in the save.

Yeah I did that. I also deleted my save files and then restored my backup. Everything is working fine

so it enable cloning then

Basically with memory editing, you will need to find what is the encrypted value of 999.999.999
Then you can do a u64 memory write with this value.

For save editing, the value needs to be decrypted & encrypted. (if you want to do it properly)

Better yet, let's find out what encryption algorithm the game uses.

Seems like they really, really went out of their way to make this as convoluted and spaghetti-fied as they could. To what end though? The outcome will be the same, it's just going to take a bit longer.

 

[Weebalicious]

If we are lucky the same things can be done with New Leaf, which sounds pretty cool. I myself, mostly looking for Time Travel related codes. Gonna be in quarantine so it would be really nice to be able to play for a few hours and pretty much already reach the next time block.

The only problem, as it was in new leaf, is remembering what time I went back to, could always just write a note of what time I left off at. Better yet if the Edizon code just edits the system time directly, but doing that manually didn't immediately effect the in game time, had to save and reload.

 

[salcri]

i think that i have found the region that holds the encryption. But i have to test a couple off things.

we can also find randomly maybe by changing the xxxxxxxx well it is not its not reliable but it's possible that it works
if someone is crazy enough to test his would give 99,999 bell or other

Don`t think it`s possible for now,you can`t reach the real address that stock the nook miles just by searching the value in the memeory like other games,maybe they use some calculation or something to hide it.,I guess

Bells are "encrypted" as ulong, stored at heap+0xAB951E4C (for Player1)

Just like New Leaf.

Basically with memory editing, you will need to find what is the encrypted value of 999.999.999
Then you can do a u64 memory write with this value.

@SciresM was the one that found the encryption for New Leaf: https://gist.github.com/SciresM/0ecc3c2b8c93922d3b21f7c4e552626c

I tried this same function in New Horizons but it fails. So they likely updated it and the only way to get it will be to reverse the game's code in IDA or similar. Until then, @Mega-Mew's method will have to suffice. Someone who reaches a high value in-game legitimately will need to share their encrypted value with us.

That is an impressive system they've got there. Props to scires for figuring that out. I will try to take a look into the executable to see if there is something similar.


On a side note, I see some references to RC4 encryption in the code.. But it may be for netcode.

Sorry I used your pointer without asking @ZiT but since it's just next to the Walk through walls offset I don't think it was really useful to make an other one
