could i get the codes for max gold nugget bundles and for the royal crown plz?
I use this to spawn 9 stacks in slots 32-40 for ease of dropping, hold L and Down to generate
edit - what's the difference of 08100000 and 04100000 in the 2 cheats btw?
2nd edit - looks like 04100000 is 4 bit, 08100000 is 8 bit

[Slot 32-40 gold nugget L+DOWN]
80008040
08100000 AC472370 0000001D 000009C9
08100000 AC472378 0000001D 000009C9

So after further searching around, I was able to create flowers with the proper genes in them, like, island pink lilies, which then can breed into more pink lilies. But, the Blue Roses still pose a challenge for me, spawn them with 0F24, then give it a gene value of fc, which should be the code for blue roses. But the blue roses when planted still only give white roses when they breed, any idea what I should try next? I am currently trying to use spawned island oranges, which supposedly will make the red roses that have 25% chance to breed blue, but so far no luck in getting reds from them. Using hex values for the genetics from here https://docs.google.com/spreadsheet...hoUSu7pE-MV7AOprBcgSY1whB4/edit#gid=312123918

Those hex values are for New Leaf, New Horizon has different hex values. If some flowers worked it was a coincidence. Blue Roses are 3F
 
awesome thanks! is there a list anywhere for the new horizon hexes?
No but you can still use the spreadsheet with a little work. For example, if you go to the binary column it says Blue Roses are 11 11 11 00 which is 0xCF. In New Horizon it’s reversed. So it would be 00 11 11 11 which is 0x3F. Use a binary to hex converter and just reverse the binary. Another example is Orange: 01 01 00 00 which is 0x50 on the chart. Swap it to 00 00 01 01 it would be 0x05 for New Horizon.

In your personal.dat, the byte at 0xB2A2 is the GetEmoticonTodayFlag , 01 = already gotten, 00 = haven't gotten
So, technically, this cheat should be setting it to haven't gotten.
Code:
[Always Get Emoticons From Villagers]
01100000 AC7B2D9A 00000000
I haven't tested because I can't use my switch atm, would anyone care to try?

Didn't seem to work. Activated it, ran past 4 villagers, nobody seemed interested. Tried entering and exiting a house & running by them again. Is there a button combo to activate it other than switching it on in the Edizon menu?

It's as if your villagers will give you a emoticon through normal play, so you will need to wait a bit.

Thanks so much for the explanation, makes sense. Question about the orange tho, it's not a direct reverse, but sets of 2? ie 01 01 00 00 reversed would not be 00 00 10 10 but like what you said, 00 00 01 01? So that rule applies to everything then, same sets of 2, but in reverse order?
