It's a good fake. But still a fake.

Ah, so it is fake. I'll just say that...man. I wish the game looked that good on my HDTV.

Total fake... but the song in Junes, is that a jap only song? Kinda catchy... reminds me of p3...
 
Edit: Def fake... translated the title... called Persona 4 Fabricated Events

" Total fake... but the song in Junes, is that a jap only song? Kinda catchy... reminds me of p3... "

If the game works like I think it does as an RPG from a technical standpoint, Persona 4 probably has a pretty formulaic scripting system that dictates how these sorts of events play out. Granted, I think some of those skits, especially the lunch-eating ones, were largely copy-paste jobs with new models and dialog thrown in, but I'm pretty sure it's still some sort of proprietary Atlus-created scripting system running underneath it all. Speaking from my own experience hacking Persona 4, the game is pretty easy to crack open with a number of tools if you know what you're looking for and how to interpret the findings, although getting the actual data manipulation to work correctly is another matter in and of itself.
 
That said, should Atlus ever retract its standing on the creation of a Persona 4 FES, I totally hope you can eat cabbage rolls with Adachi on the school roof.

I'm sure with enough time you could do whatever you want. Just look at all those videos for Banjo Kazooie from the Rare Witch Project guys.   

 
Fake but cool anyway.I hope I have the knowledge to change some enemies programmed battle tactics and stats to make the fight harder.I envy those who made this :P  

Wish it was translated in english. Specially the last part.

"How can you guys be so certain, it is fake and not deleted scenes like a lot of other scenes (eg. shopping with your s.link friends, alternative Chie link)?    Edit: Ok, I've seen the Izanami events now and its pretty obvious its fake. "

Some sort of mod, but it is hilarious.  I wanna know how they did that though. 

It's impressive how they manage to shove Adachi into all those and make it look real... If not plausible (walking in on you and Naoto studying in school just to say "hey" is something that he'd probably won't be allowed to do and Dojima would dopeslap him for wasting time futzing around with Charlie).

I do want to know what happened to those other videos. Apparently they were all deleted. Why? I have no idea.

Very well made, I can honestly say I have no idea how they managed that one.

I made this video.
This is a fake as said by others. I made this as a fanfiction video, and posted to the movie site in Japan (niconico video). 

Persona 4 runs on a scripting system as pepsiman says.
Menu dialog, events, event schedule, NPC talks, enemy's combat AI, are written by the script.
I in real time rewrote the event script by the technique for accessing the memory of PCSX2 in the process memory editor. 
As a result, the following video can be made.

Ah, so you're also the guy who came up with those deleted scene videos too, right? Were those rebuilt or are they still in the game? Also, you're Japanese? Its pretty cool that you can speak English too. It may not be perfect, but I wish I had the ability to at least know enough Japanese to read and speak it to others.
 
Oh, and welcome to Giant Bomb.

There used to be a lot more videos but they got deleted right?

Everyone loves Adachi baybeeeeeee

I fucking lost it when Izanami came floating into frame in the grocery store...

  @Bartman3010:  Yeah. I made outtake scene movie of persona 4. And, I am Japanese.
Those events are still in the game disk. For  example, E540_040.PM* is Yukiko's adopted Rank4 scene, and E540_041.PM* is outtaked scene.
However, the first half of the rank3 outtake scene of Naoto is that I did rebuild.  Because it was only NPC dialogs to remain among content of the event.

@Colf:  I was posting Japanese outtake scene to the movie site in Japan. Because they had been deleted, the video of youtube temporarily stopped opening to the public. 
Those video might be opened to the public again.
