Apparently portions of this demo were used on the factory testing/diagnosis software for the MEGA-CD as some of these images are into pictures at the service/repair documentation.
It seems software scaling on the Mega Drive got more and more polished over the years. As impressive as that last one was, games like Road Rash, Battletoads & Double Dragon, Red Zone, and F1 fared much better than this demo
Seems like it, another video shows a proto version of the special stage and Spring Yard music (differences I notice is that the special stage lacks one channel, and spring yard has different drumming (other than the fact it's using higher quality DAC))
SEGA MEGADRIVE... this demo was originally shown in Japan where Sega created the Sega MegaDrive... come on don't be lazy and use the correct term Genesis is just the U.S.A. name.
I wish SEGA Mega Drive/Genesis Had Better Screen, DAC Sound Quality and Better Mode 7 like this in the first place since 1988 more like the Arcade graphics.
Yeah, it's pretty cool for what it is. Still, it's kinda crazy how easy the SNES makes this look with its built in Mode 7 background rotation and scaling, and indeed skewing and twisting too. And I've never noticed the SNES slowing down or dropping frames when just scaling and/or rotating large background images like this either. Christ, it can hold a steady 60fps while doing all of this during gameplay in F-Zero, and even when drawing 4 fully Mode 7 screens plus lots more stuff in the multiplayer mode in Street Racer. So, yeah, for scaling very large images and even full backgrounds like this, the SNES was absolutely the king of the castle.
@@inceptional It's also worth noting that the Mega Drive came out as a competitor against the Famicom and PC Engine so, in that respect, it was the superior machine for those first couple years. There was no Sonic until '90/'91, they were selling the console on their first-party arcade conversions and sports titles which really were pretty close to the real thing at the time. On paper, it's one advantage over the SNES is CPU speed, 7.67 MHz versus 3.58 MHz. But Nintendo were a little more thoughtful in their design, they made a more well-rounded machine that was a clean cutaway from the Famicom with the deliberate intent of using custom chips inside of games to enhance the base unit. The Genesis is basically a costed down iteration of SEGA's System 16 arcade board without the bells & whistles on top of the Master System platform to maintain backwards compatibility. That 3 years made all the difference. :-)
@@robintst Yeah, and even despite coming out a couple years before the SNES, Genesis still has many strengths over the SNES in various areas. So kudos to Sega on that front. But overall I think Nintendo made the right decisions for the time, which is ultimatley why the SNES won imo. Well, that and Nintendo's first party titles, which were second to none.
your comments reek of fanboyism... This is a technical demonstration based on assembler programming, aka using the full capacity potential of the Sega MegaDrive hardware released in 1988 Japan and one year later in 1989 North America and ANOTHER year later in U.K. and European PAL regions in 1990. Custom coding to each hardware was more common depending on the dev teams and companies who preferred it over dull and slow "easier" coding languages. In fact a U.K. game programmer made some shocking early 90s racing games that were fully 3d graphics but were on PC-DOS platform and did not use any custom hardware other than the CPU but using his custom 100% assembler coding and the sad story is that the programmer I am referring to did not try to work for Sega, Sony or even Nintendo with their custom hardware. The Super FamiCom was launched in Japan in late 1990 and ONE year later in 1991 North America which is THREE WHOLE YEARS after the Japanese Sega MegaDrive launch. In 1988, Sega's hardware engineers faced design challenges to produce an affordable home consumer use videogame system to compete NOT just against the 1987 successful launch of the NEC PC-Engine but any potential and UNKNOWN threat by the "Super FamiCom" which Nintendo Japan started mentioning around either late 1987 as a "rumor" or by 1988 at a technical talk panel where they revealed they were gonna have this "Super FamiCom" ready to launch by late 1989... Whatever the case your point is moot when it comes to technology because the Super FamiCom aka Super Nintendo had the overwhelming advantage of being made with full knowledge of the rival competition's specs... a same move Nintendo used with the Nintendo 64 which yes was hands down technologically superior when it came to 3d graphics capabilities over the competition when released in 1996. Time is a factor here thus your whining that Super Nintendo is "better" just comes off as childish... technically speaking the S.N.K. NeoGeo AES launched in Japan 1990 is "better" than the Super Nintendo and Sega MegaDrive but were you alive and working at a job yourself and able to afford buying S.N.K. and the games?

SEGAは
アーケードと家庭用の連携を取ってたら、
かなり良いハードを作ってたかと
メガドライブはねぇ…ロンチがスペハリ2とサンダーブレードと拡大縮小バリバリに使うゲームで
獣王記も16Bで拡縮使ってたし、開発時期が悪かったとはいえ先見の明で無理してでも専用チップを積んでおくべきだった。
後のソニックは勿論、ガンスター、ベアナ2、魂斗羅、ヴァンパイア等の回転は当時のゲハ厨が絶叫する完成度でそれはそれで熱かったのだが。
値段的にもPCエンジンが24,800円、後出だがSFCも25,000円に対しMDは21,000円だったのでまだ猶予はあったのではないかと勘繰ってしまう。
当時のセガはACチームとCSチームの連携とか全く無かったそうだが、自分の印象ではセガCSは常にACの劣化品と潜在的に位置付けてた気がする。
最終のDCに至ってもその流れのままで、「家庭用では本気出さない」がセガだったのかな?

オブジェクトを拡縮、回転させるというのは、簡単そうにみえて当時はとても難しい技術だったみたいですね。
Xボード（アフターバーナーのアーケード基盤）ですら拡縮だけで、回転機能はなかったと聞いたことがあります。
拡大縮小回転は行列演算だから相当計算回数いるしなー。
いやいや
スプライトにしろBGにしろラインバッファハードウェアなので、ラインスキャンの際に、ドットクロックに対してXとYを両方加算すれば回転になりますし、1より小さくすれば拡大、1より大きくすれば縮小になります。
ドットクロックで駆動する乗算回路すら必要ありませんし、ラスタ毎の開始オフセット程度ならCPUにやらせてしまってもOKです。
実際、セガ系ハードはラスタ毎にオフセット指定できるようになってますし。
@@m.mishima9485 昔の拡大縮小回転可能なハードウェアはそういう仕様だったんだ。
実際にここまで拡大縮小してみせた作品はなかったし、そもそもメガCDに増設する必要ないはずですから実用レベルには至らなかったのでしょうね
積んだメガCDですら拡大縮小機能をスーパーファミコンに比べてあまり使ってない感じでしたし
技術は開発したものの、実際のゲームにはほとんど生かせてなかったですよね…ハード処理じゃないから遅かったんでしょうね。
ファンタシースターの女の子の絵は画面いっぱいのサイズなので、もしゲームに採用したら1枚１メガビット位容量取られるので、当時8メガ〜16メガのカセットでは採用せず、そういうのはメガＣＤ用に任せたのでしょう
スーパーファミコンは回転拡大機能モードでは色数をかなり落としてました
メガドラもスーファミも本来32メガ以上から性能出せる機体なのでその点は非常に残念でした(当時ゲーセンで100メガ位のゲームを家庭用に16〜24メガにして移植してました)

Hello!
メガCDのスペック表に「拡大縮小回転処理ハートウェア搭載」と書かれてたけど、結局それサブCPUの68000の事だったしなぁ。
全画面VRAMの転送速度にも限界もあるし、２軸回転以外スーファミには勝てんわな。
メガCD は 回転・拡大縮小処理のために専用のカスタムDSPを搭載していますよ。このDSPを検証するために1.5畳分のラッピングボードを作ったと石川氏が発現しています。ただ、メガCDはDSPの演算結果を直接出力できず、一度メモリへ戻す必要があるためSFCに比べて遅いとか言われていました（その分、さらに別処理をかけることができます）。CPUでやっていると言われるのは、初期タイトル等でROMタイトルからメガCDに変更になったため、メガCDの機能を使わずCPUで処理しているタイトルが多かったことから生まれた誤解でしょう
SEGAはポリゴンてナニ？て時代から擬似3Dやってたメーカーだからね（笑）メガドラのカセットとか最後らへん中身詰まりすぎてミチミチ感ヤバかったよな（笑）
