Sonic Adventure's first release in Japan - Build Date: 1998-12-10 / Public Release Date: 1998-12-23
55 days after it's unveiling at the Tokyo International Forum. 49 days before the build date of Sonic Adventure's first release in Japan.
This is without a shadow of a doubt the earliest Sonic Adventure prototype we've acquired now. It's a Not-For-Sale Promotional AutoDemo. Meaning it only shows you demonstrations / cut-scenes of the game using the games actual assets. Not just some pre-recorded FMV footage. Although it's an AutoDemo, there's a chance it might still be playable through hacking from what I can tell.
At first I thought this build was like a bridge between the Tokyo International Forum and the first release in Japan. It might be earlier than we think. Jen will tell you in greater detail. In any case, this build has got loads of differences from the final from what Jen and I could see. And that's just scraping the surface, we haven't even got to the meat and potatoes yet (I.e. all the files stored away). It can run perfectly fine on hardware. Not so much the case on emulation as the timing on the demonstrations goes off.
Unlike my previous Sonic prototype topics, I hoping to establish a potential small donation this time around. It's not required but greatly appreciated as it helps with the Sonic prototype findings; it's one of the things I do as a Researcher on Retro. Case in point, that Sonic Advance 2 in the prototype cart MSX bought off me, that really came in handy in more ways than one. Please PM me if you would like to make a donation =)
I'll leave you all to tear this apart now. I'll be posting other things throughout the topic. Enjoy!
