Refer to PKHeX's source code, because the checksum algorithm and region it verifies depends on which game the save file is for.

Read the changelog. Not every IV spread can be found, same as trainer IDs.

Not a PKHeX issue. Report plugin issues to the authors of said plugin, not here.

It's a random value, assumedly to randomize the day's interactions.

A 16 bit seed, like 0xBCFE, is also a 32 bit seed, 0x0000BCFE. Detection was added in October-2024, which explains why the "was this ever contributed" from July-2024 is no longer flagging, and the encounter is better matched. The BACD_U_AX means: set the two halves of PID with calls A and B in reverse order (B, A), which is different from Method 1/2/4 (A, B). Then IVs are set. BACD is the call order, `U` is "unrestricted", meaning it can be any 32-bit seed (well, not entirely), and AX means it has "antishiny xor" behavior when creating the PID, with special restrictions on the A call result. The "A" call gets truncated and is xored with the trainer ID and B to ensure it is never shiny. It's still flagged because the seed 0x0000BCFE is not a valid starting seed to generate the Pokémon.

You'd have to compare a before & after save file to see where the PKM's data moved; ideally by noting the PID before giving it away, and seeing where it moved in the save file. PKHeX provides the extra slots via the following logic: PKHeX/PKHeX.Core/Editing/Saves/Slots/Extensions.cs at 83bc2bf6534a2e989ec851a210ef58b8aa49c702 · kwsch/PKHeX

The main GUI exports the save file with the following code: private static void ExportSAV(SaveFile sav, string path) { var ext = Path.GetExtension(path).ToLowerInvariant(); var flags = sav.Metadata.GetSuggestedFlags(ext); try { File.WriteAllBytes(path, sav.Write(flags)); sav.State.Edited = false; sav.Metadata.SetExtraInfo(path); Alert(MsgSaveExportSuccessPath, path); } ...

Save states are RAM snapshots, and are not save files where the game saves the progress to a file for resuming from the start screen. You can use PokeGen to load the save state and extract the pkm (pk4) files for transferring to another save file. I'm not sure if it's possible to use a cheat code to toggle a flag in the RAM to allow you to save; don't think it's ever been investigated in the past 16 years since the game came out. Considering you didn't have too much progress (only up to like level 10) you might as well just start anew.

HOME has no detections for these events to flag them as hacked, even if the PID/IV is wrong. If it's fine on the development build, then it should be fine for HOME.

I'm not sure what you're asking; they should be generating out of the encounter database legally, so if you have your save file loaded (with the OT details you've listed), then they should be fine. The current release will indicate they don't match PIDIV, but as long as they have the BACD_T3 listed it's fine. Can always double check on the latest development build, which has the correct behavior now.

Fixed one of the checks in a commit just now, but these gifts are restricted to 16-bit seeds. Refer to fresh mon's from the encounter database.

Open it in PKHeX, it will tell you it is all 0xFF -- aka there is absolutely nothing in the save file that can be recovered.

Not documented really.

It was hot fixed shortly after release, just redownload the program from this site.

Compile the source code from GitHub for 32bit, or get a new computer that isn't ancient.

Try closing and reopening the program.

When saving from tabs, the program checks if the Encryption Constant should be forced to an expected legal value as a result of the Gen5->Gen6 transfer process; a common user mistake->automatic fix. When requesting legality, the program needs the latest pkm data, so it runs it through the saving function before checking. These automated fixes are very infrequent and are often tied to the GUI (like bounds checking against the loaded lists) so it's not something you can call in an automated fashion with the batch editor. You can spend the time making a batch script that does something like =Legal=false =Generation<6 .EncryptionConstant=*PID But it won't be foolproof. If there's not too many, you can just view&set each slot yourself. I suggest using the keyboard shortcuts (control-click to view, shift-click to set), which are described in the About form (accessible in the dropdowns), which is also where control-rightclick Legality (as previously mentioned) is also listed as a tip.

PKHeX applies fixes when you view a Pokémon from a slot. Read the legality report from within the slot by holding control when right clicking the slot to see the Legality option.
