Well I'm done with this cause I have my cfw switch now so I will share my save.
My save have all galar pokemons included variant forms ( ofcourse not included 7 pokemons which cause crashed )
From box 1-4 are normal shiny, box 5-8 are square shiny. FYI change SID,TID of those square shiny will make them not square shiny anymore, you have to re-roll them again.
You can deposits all boxes at one time, you will got crashed after pokebank saving which mean Pokemon still successfully deposited to pokebank.
If you got hard crashed then delete the legendaries, deposits each boxes each time... try all method to find out which pkms cause crash then delete it but I successfully transfer them to Home so I don't think you will got problems.
Galar_UltraMoonTTP-7
I was able to transfers all Galar pokemons ( except 7 mons cause crash ) at one though.
The crash will happen after disconnect from the server, not when saving.
When login Pokebank again, all pokemons should appear in the bank.
I'm too lazy to upload my save , AsteroidPizza39 save work fine, just need to delete those 7-9 crashed pokemons.
And I think download another save can't help you, to be safe you need to change OT name, PID, EncryptionConstant. Without batch editor you can't do anything.
Suggest you re-download pkhex or ask for support in forum/discord.
I think tomorrow or the next day AsteroidPizza39 will update this save, wait for it.
If you want to change some details you have to learn to use batch editor, no one can do it for you. I just saw your code have Egg_Location and EggMetDate, when your box is full of Kyurem, Kyurem can't breed/hatch.
I only trade Galarian pokemons ^^.
Already made all square shiny galarian pokemons and variant forms, now just hope those 7 can be fix and if we can make Gigantamax it will be awesome.
Wonder if we can made those DLC pokemons when DLC release.
Some code is wrong
Delete those 7 then you can transfer at easy, I have done it many times
Rilaboom, Sobble, Greedent, Gossifleur, Eldegoss, Nicket, Thievul.
Does it mean you find a way to transfer those 9 pokemons which cause crash? Actually only 7, I can transfer Scorbunny and Skwovet.
All forms for alcremie too? I can only add 9 main forms, can't edit berry flavor.
And any hope for Gigantamax?
For others: you can make square shiny if you keep random PID until it match xor 0 in gen 8, keep trying random PID and drag the pokemon to gen 8 window to check.
Thank Chewieee I was able to add a Scorbunny.
I also added some missing forms to my save like Toxtricity Low-Key, Antique Sinistea and Polteageist, Female Indeedee, 9 Base form of Alcremie ( pk7 not support Form Argument so I can't make the berry flavor and damn they all look the same in shiny ), due to Form Argument I also can't make Runerigus.
We can't make Gigantamax cause almost pokemons from the save is hatched, Gigantamax flag in pk8 still hard to handle so I don't think we can make Gigantamax in pk7.
Hope someone can figure out how to make Square Shiny.
You just need to download AsteroidPizza3 Galar_UltraMoon file then delete these 9 mons : Rilaboom, Scorbunny, Sobble, Skwovet, Greedent, Gossifleur, Eldegoss, Nicket, Thievul.
After that you can transfer all the mons. Your Bank can be crashed after saving but it's fine, all mons should be in the bank, you can transfer them to Home.
Aside from 9 mons Zesserboss mentioned, I success transfer others to Home. I'm not transfer them into game cause I like using my catched pokemon, but I have moved Sirfetch'd to game without problems
I'm also using batch editor to change the nature, in Pkhex and bank the nature was change but after transfer mons to Home the nature return to default.
How to make Gigantamax can you guide us?
