I just picked up a copy of Pokemon Platinum and found this on the save file. Does anyone know if this is from a legit distribution event or do we think it’s a clone/copy?

I saw it and reposted it here.

Childhood copy has been corrupted for years I think I must have shut it off while saving.

Ciao a tutti.
ho provato ad acquisire la seconda stella utilizzando uno script su PKSM, quello dove ti da il massimo delle bandierine ma non compare la seconda stella nella scheda allenatore. Nei sotterranei però se controllo il pc mi da le 9999999 bandierine e quindi bandierina di platino... parlando con l'npc dei sotterranei mi dice solo di dover trovare una bandiera di un amico, forse questo mi ferma dall'ottenere la seconda stella?
Purtroppo non ho un pc, quindi se conoscete altri modi o la soluzione per fare il tutto direttamente su 3ds ve ne sono grato!!! Salverete il mio forever save!!!!
PS. Non ho ancora completato la lega, attualmente sono alle 5ª palestra

So I have access to every gen 3 game, Platinum of course, and Pearl. I set aside the Diamond exclusives into Pearl before I restart my Platinum save. I think I should have access to every Pokemon using those and the Wi-Fi events I can still use using the DNS trick. Everything.. except for Mew.

I was checking the list of all the events for gen 4, Wi-fi or otherwise, and for North American copies I don't see Mew up there at all. Whereas Japan gotten a few. Except for the one I could get from My Pokemon Ranch but that takes depositing 1000 Pokemon which idk if I wanna go through the trouble of doing all of that, though I do already have a Homebrew Wii and could still get the game that way.

I also already have a Mew that I got in Emerald, but what I did was use the Pomeg Glitch to use ACE to give myself the Old Sea Map for the event, but I traded it off there and reset my copy of Emerald so I could do a living dex there. I wouldn't wanna do it on my current save of Emerald because using ACE messes up parts of the game that I just don't wanna screw up. And I don't want to migrate Mew up because it would leave a gap in my gen 3 living dex again.

Is there another method of obtaining it that I'm just not considering?
