[Bug] Japanese Pokemon White In-Game Trade considered illegal

James123 · September 12, 2017

I've recently tried checking my Pokemon White save in PKHeX, and strangely, one of the Pokemon I got normally has been flagged as an illegal mon. The mon in question is Lass Aya's Cottonee, Monmon, from the Japanese version.

This is a collection of gen 3 in-game trade Pokemon that have the same problem. I don't remember who did the Japanese FR/LG Pokemon but I did all the Emerald trades and they should all be legit.

Have you checked the illegality reason? Maybe it's flagged as illegal due to PKHeX expecting the OT name to be Dye (the girl's english name)?
It might be easier to tell if you upload the PK5 file here, but in any case, you might wanna talk to Kaphotics.

Not sure what all is different from the English Ingame trade specimen:

new EncounterTrade { Species = 546, Level = 15, Ability = 1, TID = 39922, SID = 00000, OTGender = 1, Gender = 1, IVs = new[] {20,20,20,20,31,20}, Nature = Nature.Modest, Version = GameVersion.W, }, // Cottonee

Here's the .pk5 for the Cottonee.

Language ID is 0, not sure if that is typical for Japanese Ingame trades.

Is the PID static, or is there a specific algorithm?

Kaphotics · September 13, 2017

Unrelated, but all have static PIDs.

Interesting tidbit, the Munchlax trade (when evolved) is flagged as illegal, as the incorrect ability flips back to Ability 1 on evolution.

Seems to be static, this is the one OP provided:

But I think I found it out, look at this:

The provided PK5 file didn't have a set language, so...well, I just set it to Japanese and it's all right now.

Edit: Works with any language so they don't seem to be different at all. @James123, have you checked wheter your other (regularly caught) Pokémon have the same language issue?

JP farfetch'd: Level was edited, Leer and Sand Attack come from higher levels. Typical for others (someone dropped them back to a min-low level?)

JP seedot: Ability does not match PID

Plusle: there's no way to get a volbeat at level 4, only level 5 via breeding

Hrm, this is is strange. I had the same language problem missing on my JP Black, but for a different pokemon (Basculin). My JP Black is a cartridge, if it matters.

I'm not sure if I completed any of the other trades. I'll go ahead and check both my JP Black and JP Black 2 (also a cartridge), and report back.

Edit:
This problem is exclusive to B1. (And possibly W1, gotta check that still.) Every single pokemon I traded for in JP B1 is missing the language tag. Everything in JP B2 is fine though.

@Kaphotics

Duhhhh, Monmon is from White 1. Well,it's definitely affecting both JP B1 and JP W1 with the language flag missing. I nabbed the basculin in the JP White 1 as well, and same problem (second .pkm, first is Monmon). I don't have JP W2, but it's probably safe to assume it's fine like JP B2. My JP Diamond and JP SS have no issues with the trades, from what I attached before.

Sometimes when I view a regular Pokemon in PKHeX, it's marked as legit. But when I view it the second time, it's loaded as it should be. Maybe try that?

Also, if you have any more of those in game trades. Please, keep sharing them. I collect in-game trade mons.

Kaphotics · September 15, 2017

What happens if one of these is brought up to Gen 6 (via transporter, not PKHeX)? Need to see if the language ID value gets fixed on transfer (pk5->pk6)...

I've got a fix ready to go, just need to confirm my hypothesis!

The ROM stores the encounter trade data with language IDs; I assume this value was undefined until it was noted prior to other language releases.
