Not at all. He's just referring to prototype magazine scans. Man the thing is officially a hoax and someone still wants to believe he has something. WTF :x
This was beneficial to the community. It generated interest and new things came to light, much like Geist Force, however that was much more costly.
If anything we got out of this, it's knowing that we should try to find more old JP magazines that covered these games. All the proto information we've ever seen of the Sonic game all comes from anywhere else besides Japan. I've yet to ever see any magazine previews or anything of any of the Sonic game's coverage throughout their development in Japan. Makes you wonder if Japan saw any more of Sonic 2 than we ever did.
This. There aren't a lot of Japanese articles scans about Sonic on the internet; not anywhere near as much as there are from EGM, Mean Machines, GamePro, and other western publications. In fact, the Japanese Sonic articles that are scanned are the ones that hold the more interesting bits of information. Especially this Sonic 3 Famitsu article that reveals the plans for a complete version of Sonic 3, and a Summer 1992 Sonic CD scan that reveals a completely different concept for it's special stages and it's planned March 1993 release date.
so someone coded their own version of a sonic prototype (at least partly) and someone else has taken a video of it and claimed it to be an original prototype?
So two new screen shots can be seen of the real proto here: http://megadrive.me/2012/02/19/early-sonic-screenshots/#more-4923 Most interesting thing here is the enemy you can see in the first shot. If you take close look you can make it out to look like this: (thanks to Azukara of Sonic Retro for tracing) Which matches this early concept art:
Cool found, the proto on the pictures must be a really early one. That early concept art would fit a new Alex Kidd game instead of Sonic...
