    Not sure if this was posted here yet, but it popped up on twitter recently. It's apparently an in-store demo for the Teradrive, showcasing the zoom and rotate functionality. And... it features our girl Madonna with Sonic.

    Thanks for flagging this up - it was mentioned recently in this post in the Supreme Topic of 'Other' Knowledge, but stuff does tend to get buried in there a little.

    Also, per this post, evilhamwizard is already investigating whether this ROM can be acquired, so everybody please avoid messaging the person who uploaded the videos originally - a flood of messages might damage any chances of getting hold of this demo!

    Pretty interesting piece of history. That aircraft demo at the end is much like a videogame from the GBA, Airforce Delta Storm. Sega did it first in the 90s!

    Is THAT the origin of that image of Sonic and Madonna? Like, is that another Multimedia CD demo situation? Because I always thought that image came from a early Sonic 1 demo, but here it is!

    Jack shit.
    Protos always release around protos with no coordination whatsoever, every single time.

    Yes, apparently.

    If anyone wants a video that has audio being directly recorded. This also seems to showcase more than what the other videos have shown. Proto Special Stage, Spring Yard, and Green Hill music along with Last Wave from the OutRun MD port that seems to be just like the final, couldn't notice any particular differences.

    Diassemblies and decompilations.
    Not necessarily. The variations of the Sonic 1 music you hear here come from the Sonic the Hedgehog section of the Game Toshokan's "Sega Music Collection", which sound like hastily converted ports to a certain SMPS Z80(?) sound driver (especially given the missing channel in the Special Stage music).

    Okay, this is pretty cool. I always thought Madonna and Sonic was from an early Sonic 1 build that was just never released.

    ... and people is always expecting a "good samaritan" to preserve this on the wikis (we have three wikis plus a repository... , two or three admin, two wiki sysops (one is basically a slave of the "system"... nothing against the second) plus a bunch of random editors working on them (only two or three registered on the forums... so ... technically not full members... and most of them with no technical knowledge of hardware, software, video game development, tiles, sprites etc... they can read and write... not all of them write or speak English fluently or correctly) ... and is basically this... just stuff that tends to get buried in here a little ... no offense... much love... :)
     
  12. We're getting closer to finding the TTS demo.

    Not at all, this bears absolutely nothing on randomly finding something else. This was a retail demo whereas what you're talking about was a single cartridge that Sega themselves say they've lost.

    This may go into explaining Masami Ishikawa's interview where he mentions:

    "I think its strength was in having multiple displays. We were able to have two scrolling windows — with both vertical and horizontal line scrolling — and the sprite size could be changed to fill the whole display. It could also display the background screen behind the scrolling window and could change the color of each line. The number of available colors was limited compared to comparable arcade systems, but it could create shadows that matched each character's shape and was also capable of semi-transparency. The biggest hurdle was the size of the chip. We wanted to include enlarging and minimizing capabilities as well as sprite-spinning functionality, but the circuit design was becoming too large to fit on one chip, which would have lowered the production yield rate and hiked up costs, so we had to remove it from the spec. The number of available colors was also limited by the size of the circuit structure."

    I wish we had a shooter with that aeroplane demo stuff at the end, would have been pretty modern for it's time.

    Was it like Sega's hardware equivalent to Nintendo's gba hardware? But it was unreleased just like Sega Nomad,right?

    Trying to be useful somehow.
    Red Zone is the closest you can get, although the helicopter handles like ass.

    No, that's an interview about the Genesis VDP design route, he also mentions that it was made based on the Master System VDP to be backwards compatible with it.

    Oh it was like PC. I guess Sega's first cross-play platforming in early 90's,right?

  20. Well, the demo has a version of Green Hill's theme that's likely to be from the TTS proto. And, what if it has assets from the TTS proto dummied out in the files?
