Some time ago I tried to recreate some of my saves and I wanted to level up all the Trainer Cards.
PkHeX can edit the number of the flags obtained, but if I don't remember wrong, it can't "unlock" the obtained flag because of ID's absence, so I saved right before the obtained flag and right after. 
I attach these saves (Diamond), bewteen them I have only unlocked the flag.
Can someone suggest me how I can help to find the event and implement it in PkHeX? Could it be usefull also for Platinum?

Gen 3 (pk3) through Gen5 have a max OT Name length of 7

Yes this is true but what I'm saying is that in Italian Colosseum is legal the Ho-Oh with OT's "MONTE LOTT", so PKHeX should make it as legal instead illegal.
When you trade it in the others Gen 3 games, the OT became "MONTE L" because of the length limit.

Ok now i tested it, i have used 20180911, this is Ho-Oh in my Colosseum save

and this is the same Ho-Oh, as you do, in my Sapphire save

I begin to think that the problem is the OT in the Colosseum save that there isn't in the Mystery Gift Database

I have completed Colosseum and my Ho-Oh, obtained in a legit way, is flagged as "Invalid: Unable to match and event in mystery gift database".

In BW2 the Yancy/Curtis's in-game trades are flagged as illegal "Invalid: Ingame trade invalid index?".
The meowth uploaded is an example but if you need, I can post all the Yancy's trades.

I checked with PKHeX some of my old Soul Silver's saves, and I found some pokémon caught in the Safari Zone Gate flagged as illegal (Encounter Type - See EXEGGCUTE 2014).
For this reason I have recaught a Pokémon there and I have seen that PKHeX flagged as illegal (Encounter Type - See EXEGGCUTE 2017).
Then I have tried to make it legal (See EXEGGCUTE 2014 Edited), so I have understood that PKHeX considers Safari Zone Gate's legality as Encounter Type "Buildings" but it isn't really legal because when I caught a pokèmon there the Encounter Type is "None".

No, i catched it in White 2, in the Bulbapedia link that i attached there are in the bottom (in the section Special Pokémon, above Terrakion) the two special Amoongus at Lv 47, so i think that these special pokémon are missing in PkHeX's database.

The two special Amoonguss (catched at lv 47) are flagged illegal but they are obtainable legally in Route 22
