Naruto: Definitive Edited Version Checklist

I'm not sure if there's any other Lost Media Naruto stuff I know off the top of my head. But I know a lot of obscure media. Closest thing to lost media I personally found was Bando's concept art. I had a vague memory that Bando, an original character in Naruto Clash of Ninja Revolution 2 had concept art shown somewhere but I couldn't find it anywhere online. And I started asking around with no luck. After I found my old Shonen Jump Magazines, I unintentionally found it. I really wish I had a good scanner for these kinds of things. This is a phone screenshot. If you want to find a cleaner scan. The least I can do is pinpoint the exact issue, Shonen Jump Feb 2009 Volume 7, Issue 2. 

You might wanna do your own research just in case. Because I don't if this is true, but I believe it. 
The top comment here mentions that the Cartoon Network edits were done at Viz. Not in-house like Outlaw Star and Rurouni Kenshin.

Also linked in there is a list of censorship. censorship.fandom.com/wiki/Naruto
Tho, it confused me at first. Whenever he's talking about a line being replaced. He's comparing it to the Japanese dialogue. Not some uncensored dub line. He's reading off the English subtitles on Netflix. Instead of the English (CC) subtitle track. I think the movie-censorship link I previously sent is a clearer documentation since that has pictures. 

Now about those Japanese VHS Tapes you mentioned. I...don't know. BUT! I'm guessing that its the Broadcast version. Worth the gamble. 
Taking a Generation leap forward. My Hero Academia releases a handful of Broadcast episodes to DVD in short bursts, THEN when the season is over, spend time doing corrections and release a polished copy in a couple Blu Rays. So, I'm assuming this is the standard and might've been the case with shows back in Naruto's era. Where the VHS could potentially be the broadcast copy, and the DVD is released later, containing corrections. 

This was the only proof I could discover of the disclaimer of the episode.

It's from the first episode

I don't remember the disclaimer being that bold. I could've sworn it was a skinnier font. But "Moderate violence". That's definitely it. It being made for Episode 1 definitely sheds some light on why it's a random shot of the Academy. They just reused it for #140.

It never did, the shot that is used for the 140 disclaimer was taken from a still-shot of the ninja academy from the first episode.
