Do you have an antivirus program scanning your downloads? generally that would happen when such programs see the .exe as potentially malicious. PKHeX (24.03.10).zip seems to download and unzip ok here. SHA1 is: 0701d5a43d34e274affe7463ed860ee94f0cd315 Size: 23.2 MB (24,427,674 bytes)

Cheers for the tips, I got PKHeX working great on my laptop running Pop! OS 22.04 LTS. First I installed Wine as per the Ubuntu 22.04 instructions. I couldn't seem to get Wineticks to install dot.net 7 and dot.net desktop 7, however I simply downloaded the 64bit installers from here: https://dotnet.microsoft.com/en-us/download/dotnet/7.0 and installed the .exe as you would on Windows. After that I could run the PKHeX perfectly fine:

If any Japanese Gen 2 events have got preserved I don't think any of them are available available online to my knowledge. The saves would have had to have been dumped a long time ago now due to the battery in the cart dying, or transferred to Pokémon Stadium GSC.

The save you have uploaded is 64KB, a full save should be 128KB. This is probably why Pokemon Box thinks the save is corrupted. How did you dump the save? and are you sure your copy of Pokemon Emerald is genuine? I've seen fake copies where the save is only 64KB.

You can restore your save game to an actual GBA cartridge using a DS Lite and the homebrew app GBA Backup Tool, then migrate it though the generations as normal. Or use PKHeX to migrate it to Gen 7 and restore that save on a 3DS with CFW installed. You can then use Pokemon Bank to move it from your Gen 7 save to Pokemon Bank, then finally migrate it to Pokemon Home and move it to a Gen 9 game from there.

I would probably be sensible and restore your saves, then boot back in to OFW before going online if you wish to be extra careful. I’ve always tried to be sensible using CFW on my Sysnand. To be honest all I have ever done is boot Atmosphere with my Switch in aeroplane mode, backed up my saves with JK's Save Manager, then powered my Switch off again.

You might be able to do the release of what is mentioned here: https://www.reddit.com/r/AnaloguePocket/comments/zrwryl/backup_save_data_from_physical_cart_on_the_pocket/j1dknni/ Create a save state (memories) when playing your actual physical game, then do as that post above instructs, however load the memories playing a rom of the game via the Spiritualized GBA openFPGA core. You would then save in game and have a raw save file that is compatible with PKHeX. That could in theory work, however I have not tested that. This post is worth a read in regards to Pokemon on the Analogue Pocket: https://www.reddit.com/r/AnaloguePocket/comments/11fpbat/definitive_guide_to_playing_pokémon_on_the/ If you have a DS or DS Lite + Flash Card, using the homebrew app "GBA Backup Tool" is by far the easiest way to backup and restore a save to a genuine GBA cartridge. A similar save tool could eventually be created for the Analogue Pocket, however I don't think such a tool exists yet. Edit - this looks another potential way to extract the .sav from the .sta file you have: https://www.reddit.com/r/AnaloguePocket/comments/10ampwi/solution_for_extracting_pokemon_emerald_cartridge/

You can update offline with "Daybreak", which is a homebrew app included with Atmosphere. Simply Google "switch firmware archive" and you will find Switch firmware you can save to your SD card and update with. The guide SkyLink98 posted covers this and everything else required from start to finish.

On the Nintendo Switch to the best of my knowledge these Pokemon are not currently obtainable in any game: Snivy, Servine and Serperior Tepig, Pignite and Emboar Patrat and Watchog Pansage and Simisage Pansear and Simisear Panpour and Simipour Blitzle and Zebstrika Sewaddle, Swadloon and Leavanny Ducklett and Swanna Furfrou Pikipek, Trumbeak and Toucannon Minior Meltan and Melmetal However you can obtain them all except Minior from Pokemon Go. Keep in mind Pansage, Pansear and Panpour are regional Pokemon on Go, so depending on where you are in the world you'd only be able to get one of the three without trading with someone local to you or waiting for an event. Failing that you'd have to trade on home for them or import from the 3DS.

Keep in mind if you have dumped an existing save from the VC game using Jksv or Checkpoint and are replacing it with another you need to delete the "SecureValue" file which will be in the folder with the sav.dat file. If you don't do this in my experience the VC game will think the save is corrupt if it has changed in any way (which it has if you are replacing it with a different save). Also some emulators append more RTC data to the end of the save than what the VC game expects to be there, to fix this for Gen 2 games I open the save in a Hex editor such as HxD and delete anything after 00008000: The size of a valid save should be exactly 32.0KB (the size on disk is irrelevant and could vary depending how your hard drive is formatted) If the save is the correct size its most likely the SecureValue that is giving you the problem.

We could learn more about the Mew / Celebi machines and software used for the Gen 1 / 2 event distributions. I suppose their is always a chance more concept art or prototypes leak at some point, one thing is for sure the last few years have proved anything is possible in regards to unseen or obscure Pokemon content surfacing. With that in mind I think their will always be something new to learn, even if we think we know most of it now.

Both the Pokemon Distribution Machine Gen II / Gen III discs are dumped, along with the memory cards. So from a data preservation point of view that data is safe and backed up which I'm pleased about. The original hardware went on to someone at Project Pokemon interested in getting this working for all to enjoy, so it's great that ended up in the best possible place for the Pokemon community to hopefully one day be able to use these distributions in some way. The data not been out there for anyone to freely tinker with years later is not an ideal situation I agree, hopefully that is something which can be changed. Deoxys explained the situation on emulation and what works / doesn't in far more detail here: https://digiex.net/threads/pokemon-gen-2-3-pcny-distribution-machine-save-downloads.15872/#post-82340 - worth reading if you haven't already.

Windows 7 will be the problem, Microsoft discontinued support for it 3 years ago. You need Windows 10 or 11 for .NET 7. You can actually still upgrade to Windows 10 for free from Windows 7 even though its not advertised. Chances are if your hardware supports Windows 7, Windows 10 will also work fine: https://www.microsoft.com/en-gb/software-download/windows10 - only do that if you are confident you can fix your system if anything goes wrong during the upgrade process however.

Are you running a 64bit version of Windows? if so what version of Windows? I initially got the error about updating the .NET framework: However after updating everything seems fine on Windows 11 22H2.

You need to use a save manager to dump the save and restore it once you have made edits with PKHeX 3DS Pokemon Games: JKSM: JK's Save Manager for 3DS NDS Pokemon Games: TWLSaveTool: A 3DS homebrew that allows you to read, write, and erase save files from NDS cartridges
