To my knowledge, not every move can be mastered with a Seed of Mastery, (specifically moves not found in the Move Shop and learned via Level Up)

Pretty sure this in theory should be able to work in-game and be legal

Try testing it ingame to see if it's actually possible, the mechanics don't always work the way you expect.

All of them are from Pokémon Emerald which makes them not compatible with Pokémon colosseum. 

The reason why Pokémon colosseum does not allow Dexoys from emerald is due to the event not being released in the United States for Emerald but only for Firered / Leafgreen from what I've researched.

That's false, the Aurora Ticket was released for FRLG in every cart language, (and multiple countries), and for every language of Emerald (except Japanese):

Use the encounter database under Tools > Data. Do not try to generate Pokémon by hand if you don't know the exact parameters required.

if you manage to fix it, can you tell me about it?

Open Tools > Data > Batch Editor in PKHeX, and run this command to have PKHeX automatically suggest move mastery flags:

.MoveMastery=$suggest

That savefile is the incorrect size. Pokemon saves from Emerald should be 128kb, not 64kb.
Fix your emulator settings to use the correct savefile format, you want Flash 128K.

If your current savefile doesn't load after changing this, make a savestate before changing it, and load that savestate after adjusting the settings, then save ingame twice to generate a new savefile with the correct size.

(You may want to move your current 64kb save out of the savefile folder before this so a new "correct size" one can generate)

1: Impossible to know without the original to compare to.
2: Same as above.
3: Presumably there was a partial save recoverable despite the battery being dead, or the battery was not completely dead.
4: If they appear legal in PKHeX, you will almost certainly not be banned for using them online in modern games. Nintendo has very poor hack checks to begin with, but keep in mind that any pokemon obtained from Gen 1/2 events, or from Pokemon Stadium will not be legal in the Virtual Console copies of Gen 1/2 or in modern games.
5: Short of taking it apart in a hex editor and looking for things that "look like it could be pokemon data", no. Whatever you recovered is likely all there was, and also that has nothing to do with being banned online.

Also, in the future, please do not post the same thing twice. It doesn't do anything but create needless spam, your repost has been hidden.

To my knowledge, there is no early game restriction to importing pokemon from HOME into your saves, in SWSH, BDSP, or PLA. Exporting pokemon into HOME from those games on the other hand, does have some restrictions.

In SWSH, LAN Mode can be enabled by going to the options/settings menu ingame and holding L & R, and pressing in the Left Stick like a button.
LAN trades on the other hand, are not something we're going to assist you with here, as it's primarily used to distribute wildly illegal pokemon that would otherwise be blocked via SWSH trade servers, and that goes against our policy of "please do not cheat at the expense of others". Handing out illegal (and potentially bannable) pokemon would obviously qualify.

See this thread:

Your best option would be to install AutoLegalityMod, configure custom trainer data, then use the "Generate Living Dex" option.

It should be possible to disable FIPS Mode, that may resolve the issue.

Any met date that the system date/time can be set to is legal with the exception of Pokemon Go, HOME gift, and Legends Arceus mystery gift Pokemon. While 2004/2006 are not "realistic" Pokemon Bank/HOME won't see anything wrong with them. 

The savefile verification seems to apply when more than one person uses the same savefile online. If you are modifying your own savefile, and have not shared it in part/whole with any other user, there shouldn't be any risk.

I suggest following one of the guides where you manually edit your own clothing blocks, but the block shared here appears to be safe to use and has not triggered the savefile verification lockout:

If I am wrong, plz, is there other way to get a legal Shiny mew through pkhex? And how to? 

There are only two legal Shiny Mew that can exist outside of physical cartridge copies of Gen 1/2:

1. Japanese Emerald players who obtained the Old Sea Map event item were allowed access to Faraway Island, the Mew there was not shiny locked and could be shiny hunted.
2. Pokémon GO gave a Shiny Mew to players who completed an event. (Shiny Mew Masterwork Research)

The PCNY Shiny Mew that was available in Gen 1/2 was exclusively available in Gen 1/2, it cannot be moved out of those games, as no legitimate method exists to transfer Pokémon from Gen 1/2 cartridges to Gen 3 through 8.

You can use the encounter database to obtain either Mew, although for the Japanese Emerald Mew, you will also have to look at the PID Mismatch guide to change the stats, or make it shiny (That Mew is Gen 3, and uses Method 1 RNG):

If you are unable to change the IVs, Nature, etc. it's likely due to PID Mismatch, the RNG restrictions of the game do not allow you to change stats freely, they must all match each other.
See this page for tutorials on how to solve this issue:

You may also want to install PKHeX-Plugins and simply use AutoLegality to solve it for you.
https://github.com/architdate/PKHeX-Plugins/wiki/Installing-PKHeX-Plugins

We don't provide that service here. I suggest either purchasing Pokemon Bank and Pokemon HOME to do it yourself, or finding a Sysbot.NET instance and having the bot trade them to you in Sword/Shield. (or BDSP/Legends Arceus when the bot is updated to support HOME transfers for those games)

Hi, I've removed your uploaded savefile, we do not allow uploading of Legends Arceus savefiles here because they have savefile verification and it poses a potential risk to anyone using the savefile, including you. Please do not upload your savefile, nor parts of it.
Please see this post for more information:

For the most part, yes. There may be some niche feature that was left in RNG Reporter, but it's likely either redundant, or severely underused.

If I understand it correctly, Reverse Method 1 is the method you want to use in Pokefinder. RNG Reporter is retired and outdated, Pokefinder is the recommended software for most RNG abuse and the spiritual successor to RNG Reporter.

If that doesn't work, I'm unsure if BACD_U has support in newer programs, but Pokegen's PID Finder does support it.

You are looking for the battery file, the extension should end in .dsv, you should look up "Desmume savefile location"

A savestate is not the same thing as a savefile, you have to save ingame normally, like you would on a real DS, to generate a proper savefile. 

If a Pokemon is illegal in a box/party slot, but legal when viewed in the editor on the left, that means PKHeX auto corrected some value. Hold Control and right click on a Pokemon in a slot and select "Legality" to legality check it without loading it into the editor, that should reveal what the initial issue was.

You asked this in our discord earlier and received an answer already, but I'll repeat it here:

Hoopa does not exist in Sword/Shield. It is not coded into the game, the 3D model, animations, stats, etc are quite literally not in the game. This is true for 234 species, none of which can be generated or transferred into Sword or Shield:
https://www.serebii.net/swordshield/unobtainable.shtml

So no, you cannot put Hoopa into Sword and then HOME, because you can't put it into Sword to begin with.

The format of the savefile is different between game versions. Changing one value doesn't magically fix the size or format of your savefile.
If you do not have an older backup of your savefile from 1.1.0 or earlier, you're probably just out of luck.
If you want to develop a tool that trims off the extra data and converts the savefile back to an earlier game version, or try to do it by hand, you're in mostly uncharted territory.

Firstly, modifying the ROM to achieve this would be much more difficult, and require you to likely make a ROM hack using none of the existing tools for randomization/ROM hack making, you'd be on your own digging through the ROM by hand if someone hasn't already added this feature to an existing ROM hack tool.

If I just simply change their level by PKHEX its kind of spoil the whole journey and effort I devoted on that mon, cauz once I can modify the level, cant anything else not be changed?

Secondly, this is an arbitrary line in the sand you're drawing. By the same logic "once you modify the ROM, cant anything else be changed?" You could just as easily modify the ROM to make every trainer battle have a single level 1 Wurmple, or make your pokemon's species have Ghost/Dark typing and Wonderguard.

If you're going to cheat, it's silly to dance around the cheat that you consider to be "too cheaty" when arguably your loophole around it is worse.

It's entirely possible for you to have had level 50 pokemon, that's a legal state for them to exist in, but altering the Battle Tower to permit level 51+ Pokemon into the level 50 difficulty would both be an impossible state for the game to exist in, and wildly unfair considering the Battle Tower trainers would still be limited to level 50.

The EC (Encryption Constant) is located in the OT/Misc tab of PKHeX, near the bottom. If you're looking for a specific pattern, try Spinda Painter:
https://gatorshark.webs.com/Spinda Painter.htm

You have to complete the Cresselia event first. Many players are not aware of this and complain before looking at the typical ingame requirements.

Are you sure you've met the ingame requirements, PKHeX aside?
