When Super Famicom was first released in Japan a promotional video was sent out to press outlets. This hour long commercial was uploaded to youtube recently. I didn't put this in the rare gaming section cause I watched it about 5 minutes and didn't see any prototype footage. Looks like it's all final.
Not that rare. I've seen a few of these of YJA. I haven't bought it though, so thanks for sharing the link.
Almost as rare as your Super Mario World "prototype" huh? Only seen three, oh yeah that's totally common. Lemme pop down to Goodwill and scoop one up.
Again, that thread was a joke, was never meant to be serious. And I apologised numerous times. By the way, I'm not kidding. Here's the link to a few of them. http://page2.auctions.yahoo.co.jp/jp/auction/b220075927 I believe there was category's for the popular games. The link is to the Super Mario Perfect Video ones. They also made a few for the N64.
The reason I mentioned the rare forum is cause that's where prototype threads usually go. But now that I've watched through the whole video I can see I categorized it correctly. Everything seems final.
There's a few of these types of videos on Yahoo right now. Came across one with Battle Zeque Gaiden as I was checking the prices for the game.
