[@DMMDestroyer]

Having had never even seen one of these in person, thanks for sharing these titles. The effects at 19:34 really do show what it was capable of and it's a shame Sega didn't put effort into titles for the system. At the end of the day, it's about games and that's truly what makes or breaks a system's success. This continues to be one of the top quality video game series on KZbin.

[@TheFancifulNorwegian]

I remember EGM claiming at the time claiming that Silpheed was a genuine honest-to-god fully-polygonal game. Admittedly it pulls off the illusion quite well (as did the SCD port of Starblade, though the dithering there gave it away more frequently).

[@23Scadu]

Not entirely incorrect since all the all the actual gameplay elements are real-time (or quarter-time?) polygons.

[@TheFancifulNorwegian]

​@@23Scadu Per the video (and I've read this elsewhere) the gameplay elements like the ship and so on are actually pre-rendered sprites. They do seem to be made up of a limited number of animation frames-for example, spinning objects have a short cycle of repeated frames instead of moving smoothly with a large set of different angles depending on the perspective, as one would expect from fully polygonal models.

[@misterjonestech1611]

@@TheFancifulNorwegian I had Silpheed, and I remember reading somewhere back in the 90's that the Sega CD's hardware had limited 3D capabilities: No textures and a max of about 100k polygons on screen (or was it 10k...) and Silpheed was one of only two titles that took advantage of the 3D features, the other being Stellar Fire. Silpheed's entire game was supposedly all generated in realtime with polygons, which is believable IMO. When I worked at Funcoland in the mid-90's we used Silpheed and Stellar Fire in our SCD display unit to attract attention to it.

[@MaxAbramson3]

@@misterjonestech1611 That's a bit complicated. IIRC, the Genesis could texture up to 1,000 in software, while the 12.5MHz 68000 "sub-CPU" in the Sega CD could add another 2,000. That's not far off from Virtua Racer (100 polygons at 30fps at a time when characters could be 10-30 polygons), but worse than the 5-20,000 of PlayStation launch titles. However, adding the powerful ASIC-DSP graphics chip, much larger quads could be scaled, rotated, and warped to provide the appearance of much larger, more ambitious 3D. And the CD-ROM's FMV capability sucked b***s for straight video, but could work well for either the background or foreground layer, ala Silpheed. There are other techniques like color cycling and changing the location of the background x- and y- each scanline that consume very little CPU time, but provide effective Mode 7 appearance for both sky and ground.

[@litjellyfish]

For soul star the sprites are indeed scaled in real-time. Sarah Jane Avory wrote up some article in how she did it. In most sprite heavy levels the background itself is just a set of looping prerendered image compressed to tiles often flipped in X Y to save tile memory and have less data to transfer. And on top of that is the real-time scaled sprites that then are transferred to the Megadrive (shared vram space with background tiles if I am not wrong) That is also the reason they can wobble. As you can do this effect with the sprites themselves it’s done on the mega Cd before sending it to megadrive and be rendered using regular sprites.

[@DoggoneNexus]

Core Design really did seem to have the best handle on the Sega CD's capabilities and how best to utilize them. I feel Thunderhawk or Battlecorps deserved a mention.

[@bigbabatunde1218]

The Mega CD wasn't around for long enough for developers to 'push the system'. Pushing a system to and often beyond its official limits generally comes later in a system's lifespan such as can be seen with Toy Story on the Mega Drive and Donkey Kong Country on the SNES. The Mega CD simply wasn't around long enough and neither did it have the overwhelming backing by developers to run the usual and expected course of system pushing.

That’s very interesting about the Mega CD being bandwidth limited, I hadn’t realised that. I wonder if that’s why Sega went with overlaying the 32X’s graphics via the pass through video cable?

[@3rdalbum]

Must be part of it, at least (and the other part being that the 32X would be able to avoid constructing sprites out of tiles or having to be limited by the Mega Drive's colour palette). The 32X could use the Mega CD, and if both the Mega CD and 32X were trying to push complicated graphics into the Mega Drive's RAM you'd end off with 5 frames per second :)

It blows my mind that in the 90's there was like one and a half console generations where devs all just decided that frame rates didn't matter.

[@BurritoKingdom]

The 32-bit/64-bit generation and the PS360Wii generation had the worse frame rates. I remember so many PS1 and N64 games that were between 10 and 20 fps. The PS360Wii tried to aim for 30fps but failed most of the time except for COD and Halo. Surprisingly the DC/PS2/GC/Xbox had the best frame rates of any 3D console generations. The PS2 has the most 60fps 3D games unless you count the backwards compatibility of the PS5 and Xbox Series consoles. I'm guessing the jump to HD was a bigger demand than expected. I'm really hoping this new gen prioritizes framerate over 4k or god forbid 8k.

[@23Scadu]

@@BurritoKingdom On the current generation it seems to be pretty common to offer both a 60 fps performance mode and a 30 fps "cinematic" mode. I wonder if anyone genuinely uses the latter though, other than for screenshots.

@@BubblegumCrash332 oh god no. Framerates weree shit during the PS360 era. Most of the 16bit era were 60fps since it was 2D.

[@davidmcgill1000]

The Batman games and Soul Star do look rather playable. One thing that puts Soul Star in the far lead is the fading colors in the distance, something you'd see done on F-Zero with HDMA. It does look like they actually knew what they were doing which can't be said for the other games.

As far as the "3D" scaling goes, Sonic 2 did that an entire year before the CD came along. In 1992 and super smooth in those half pipe bonus stages.

[@MaxAbramson3]

Honestly, if SEGA had just built the original stock Genesis with the faster 12MHz 68000 (from the Sega CD) and doubled the RAM and VRAM to 128KB, the system could've launched at $249, and the Sega CD and 32X wouldn't have been necessary. Why? Because, after the overhead of processing game input, they'd go from 1 MIPS to 2 MIPS available (so wouldn't need the extra Z80 and 8KB audio RAM bolt on), could've added a 4,096 color mode, and could even have handled scaling, rotation, and polygons in software. Arcade ports like Hard Drivin play at 4-5 frames per second on the Genesis. Overclocked to 10MHz, that goes up to 8-10fps. And at 12MHz, you've got a smooth 12fps, all with the VDP still displaying what it has at 60fps. The 1,000+ stock Genesis/Megadrive titles like Sonic 2 could've done much smoother scaling and 3D animation, arcade ports would've looked much better, and we likely wouldn't have suffered through the Sega CD, 32X, SVP Lock On, Neptune debacle of 1994-96.

[@3rdalbum]

I can't imagine how difficult it must have been to program this thing to the best of its capabilities: 1. It would be easy to program the Mega Drive to do most things and just utilise the Mega CD for storage, but then you'd just have a game that looked no better than the Mega Drive. 2. Or, it would be easy to program the Mega CD to do most things and just utilise the Mega Drive as a glorified video output device, but then you'd run into bandwidth problems and have a super low framerate. 3. Or you could program the Mega CD and the Mega Drive to work in conjunction with eachother. Essentially be programming two different systems at once, keeping them synchronised, passing data and code from one system to the other, programming in stamps and background layers on one and programming in sprites and tiled background layers in the other; making sure you don't overwhelm the bus or the Mega Drive's memory bandwidth... it must have been very challenging indeed and it's not surprising that most developers seemed to pick option 1 or 2, rather than option 3.

[@Sharopolis]

I've looked at Sega's official docs from the 90's about the system and they are not good. If that's all they had to work with I'm not surprised developers found it hard going. Sony apparently did way better with the PlayStation in that regard.

[@MaxAbramson3]

@@Sharopolis And this problem would further plague the 32X and Saturn, resulting in hundreds of subpar third party efforts that had to be rushed out giving SEGA a bad rap. ATARI pushed this poor support approach to the limit, and even SONY didn't really hit their stride until late 1996-97.

[@AnthonyRiddle]

Sega's trio of machines should have been marketed as an arcade cabinet in your living room. The Genesis, Sega CD, and 32X together were capable of having near arcade perfect ports of every single Sega arcade game until the Model 2 board came out.

[@fattomandeibu]

The Mega CD didn't have enough RAM for arcade ports for the most part. It's why the WWF wrestling games didn't feature tag matches or battle royales, the meagre 512KB RAM(the other 256KB was reserved for the CD streaming media buffer) that everything had to fit into wasn't enough to hold the sprites for more than 2 wrestlers at once. It's why Final Fight, rather than Street Fighter 2, was the Capcom arcade game to be ported. There were other issues too, but the main one is a CD drive just can't load data fast enough to keep up, so it was useless for anything beyond some ports of basic cartridge games with CD audio, or FMV video stuff.

[@AnthonyRiddle]

[@Banderpop]

Thank you for the insights on Silpheed. On other videos and their comments, there's still a lot of uncertainly as to how the graphics were made up. I've always thought that the backgrounds probably use run line encoding, and the smaller objects fully use polygons, but the 4 frame updates on the sprites is something I'd never picked up on. I wonder if the older home computer versions of Silpheed also did this. An unmentioned trick that Silpheed used was constant colour cycling, like parts of backgrounds that pulse between red and black for example, that in motion adds to the impression that there's a bit more animation and more colours than there really is, helping to disguise the use of pre-rendered backgrounds. I've always thought that Batman Returns looked better than Batman and Robin. Partially because I don't think the cartoon look pairs well with sprite scaling. But also because Batman Returns has so much more going on with sparks occurring during collisions, flames appearing on vehicles, and massive explosions with lots of scaling, rotating debris flying everywhere. Most of all Batman Returns deserves more recognition for its physics though. Perhaps the Mega CD could still have been pushed much further, using some of these tricks in combination. But not before the newer consoles came along, able to do all these things but better and with so many more colours.

[@Sharopolis]

The backgrounds on Silpheed really are interesting. As I said in the video I'm just not good enough at reverse engineering to really find out what's happening. The sprites update out of sync with the backgrounds, it's one frame after, maybe during the next vblank. But they do all change together.

Well done! I love the Sega CD and it is one of the reasons why I am a retro gamer today. The Adventures of Batman & Robin looks like something you would find on the PS1 and Soul Star and Silpheed still look amazing. It is so sad that the game engine for Batman & Robin wasn't used more in other games such as being used to bring home all the amazing 32-bit super scaler games Sega had in the arcades. That fact is made even worse when you consider they did the same thing with the 32X. Space Harrier and Afterburner on the 32X are amazing. A proper arcade port or sequel to Super Manoco GP using that engine or a refined version of the Beyond The Limit game engine would have been amazing. This game engine would have been amazing for a Super Thunderblade game. It is a crime the game engine of Soul Star was not used more. Again, the Sega CD is one of my favorite consoles and it is one of those game systems that look better via composite cable connection. Keep up the great work! Here is hoping that some indie developer would make system limit pushing games for the Sega CD & 32X. They could even leverage their costs by selling them on Steam but I know I and many others would fork over the money to buy physical releases for the Sega CD and 32X.

[@GreyMatterShades]

I'm also hopeful that indie developers will start making Sega CD and 32X games, but it's not going to happen in large numbers unless SGDK gets updated to support those devices. In case you don't know, SGDK is a development tool that is used to make most modern indie games for the Genesis. It allows developers to make their games using the C programming language rather than the much more difficult Assembly language. Hopefully the makers of SGDK add in support for Sega CD and 32X in the near future, as the potential of that hardware was never truly realized imo. While a few developers have tried making games for those platforms without such a tool (like the improved port of Doom for the 32X), most indie developers wouldn't tackle such a project.

[@MaxAbramson3]

@@GreyMatterShades I'm actually trying to get SGDK to work on my system. I'm good at writing performance code in Assembly, but many people have had problems trying to get SGDK to actually compile the included example code or even download all of the components. Much worse is the fact that those old systems (like System 16/Genesis) are alien to modern software developers, and most don't really have the time to get into it.

[@GreyMatterShades]

@@MaxAbramson3 Yeah in my experience SGDK is pretty finnicky to get going. I used info from the youtube channels Pigsy's Retro Game Dev Tutorials and MatteusBeus Retro Sega Game Dev. Pigsy's channel has a playlist for SGDK development and one of the early videos refers people to Matteus' video on setting it up. Once it's going it works pretty well, it's just the initial setup that's tricky. Most modern developers wouldn't bother to try making a Genesis game, as it would require learning a bunch of new skills and working within extreme constraints, when they could just make a 16-bit style retro game using modern software with much fewer limitations. For me as someone who's never made a game but always wanted to, the idea of making something for the Genesis is appealing because of the constraints. I'm hoping that working with limited hardware will force me to simplify and focus the design around what's possible for the system, meaning I'll wind up with a simpler game of a more manageable scope. And other developers have used SGDK to make some pretty impressive modern Genesis games like Demons of Asteborg and Life on Mars. I'm sure if Sega CD and 32x support were added to SGDK, some developers would be thrilled to make games for those platforms. It would definitely be a small niche of indie developers, but they could probably produce some amazing stuff!

[@MaxAbramson3]

@@GreyMatterShades Yeah, I've made a few games over the years. I've worked on many systems, but the Genesis is supposed to be easy to develop for. My think is limit pushers. I want to see if that powerful VDP can be pushed even a bit harder, maybe in 320x448 mode.

[@GreyMatterShades]

@@MaxAbramson3 Yeah hopefully in the coming years we'll see people push the Genesis further than its gone before. There are people putting up test videos doing 3D graphics on it without any sort of extra hardware like the Super FX chip for the SNES, so there's promising stuff happening. I really hope it translates into some great games too. I think the internet helps a lot as well. I got the impression that back in the 90's developers weren't as open about sharing tips, techniques, and experiments, but these days most people are happy to share what they're working on and how they accomplished it.

[@birdrun4246]

The reason there's a 16 colour limit on the scaling/rotating backgrounds is because the Megadrive's 64 colour palette is split into 4 16 colour sub-palletes (making the actual pixel data four bit per pixel, 2 pixels per byte). Each background tile and each sprite can only draw from one of the four sub-palletes. For normal backgrounds you can have several sub-palletes in use but as soon as you start rendering 3d (software or using external hardware), the tile boundaries don't line up with anything meaningful, so it's near impossible to use multiple palettes without causing ugly ZX spectrum style colour clash. Same thing would apply with FMV.

[@MaxAbramson3]

16 colors for the background, 15 for the foreground (0 is reserved for transparency), 15 for the sprite layer, and 15 more for the window. And you can change some or all of those on every scanline, so you can theoretically get 512 out of 512, though 100 seems to be the practical limit on games. Using Shadow-Highlight Mode, Toy Story is able to display 145 out of 3,375 colors. Using color blending, one could theoretically get about 1,000 out of 20,000 colors photos, though no games actually pushed those limits. You could also use a special interlaced mode drawing 320x448i to the screen, making Saturn-like 2D theoretically possible.

[@birdrun4246]

@@MaxAbramson3 Yeah. I'm assuming if you're doing fmv or scaling/rotating, that would normally go on the background layer, so practically you'd get 16. You could probably improve fmv a great deal by updating the palette per scan line, but I'm pretty sure there's not enough time in hblank for a full palette update, and I assume FMV decoding already uses most of the CPU anyway

@@birdrun4246 The Genesis and even the Master System could update one color palette during HBlank if you don't waste time with interrupts.

@@birdrun4246 You don't have to use hardware interrupts to do it. NES games had to have code running in parallel on the 6502 and its own version of the VDP.

There are a lot of techniques like color cycling and DMA moves from cart to VRAM that don't consume a lot of CPU time, though DMA moves can monopolize the bus stalling the CPU.

[@birdrun4246]

@@MaxAbramson3 That would be interesting -- since you're usually only using one palette (16 colours) for FMV, you'd have time to do a full update every scanline. Might do good things for video with the right precalculations.

Now, TIME FOR HOMEBREW Edit- and in PAL, you can DMA 16K per frame, or double using the special 128K graphics mode that was never used. Same on NTSC you can jump from 7K to 14K this way, or all the way up to 25K if you’re willing to shrink the screen down to 320x200.

I've always found Thunderhawk's tilting horizon oddly impressive. I don't think any SNES mode 7 game ever did that.

[@TheFancifulNorwegian]

I think you could fake a tilting horizon in Mode 7 by using one edge of a tilemap. But you would have to severely restrict the player's movement to prevent the left and right edges (from the player's POV) from coming into view, because otherwise the whole thing would look like a weird flat earth where the ground just suddenly terminates in a big void. So you would practically be limited to forward and backward scrolling with a little bit of left and right movement, as opposed to the free roaming in Thunderhawk. Also I'm not sure it would be viable to pull off the calculations needed to keep the perspective correct.

[@julianregel]

I think the tilting horizon in Thunderhawk is actually the Megadrive's VDP column scrolling feature, which would suggest that the MegaCD's graphics chip is drawing the "Mode 7"-like landscape in traditional way and passing those tiles the VDP which then does the tilting.

[@TheFancifulNorwegian]

​@@julianregel This seems right given the way the tilting effect comes close to breaking up at the extremes of the allowed movement, which is typical of the column scrolling since it was limited to 16-pixel strips. The SNES also had column scrolling that was theoretically better than the MD's implementation-it worked with 8-pixel strips and could therefore be "tilted" further before the image started to break up-but it only worked in a few background modes and Mode 7 wasn't one of them. Star Fox used the effect for its horizons, but it's not as impressive as Thunderhawk since it's only applied to a traditional flat background layer.

Many complain about the lack of Outrun port but the way I see it, back when the Mega CD was released, the likes of Outrun and Afterburner were knocking on for half a decade old. If ports of these games had been released that were closer to the arcade (low framerate notwithstanding) I don’t think they would have made any difference to the fortunes of the add on. Also releasing ports of old arcade games would’ve gone against Sega’s marketing campaign about the Mega CD offering next level gaming. That’s not to say I wouldn’t have loved the Super Scaler games to be released for it, it’s just I can see why they weren’t.

[@MaxAbramson3]

Irony is that arcade scaling could be pulled off using superscaling hardware or through prerendering and loading 20-60 prescaled sprites onto a CD-ROM, then decompressing and loading them into system memory. SEGA could've just made a $150 addon with a 2x CD-ROM and just had developers do all of their scaling, rotation, and 3D graphics ahead of time. Or, they could've just added the ASIC-DSP and 12MHz 68000 to the stock Megadrive/Genesis (and filled out the original 128KB of VRAM) and gotten 90% of their good games onto 16-40 megabit cartridges. Oops.

[@MaxAbramson3]

"Only 20fps." You punk kids these days don't know how good you've got it! I believe that it's due to the difficulty in loading the original tiles to the stamp maps, scaling them, then moving those tiles to the Genesis VDP. I don't believe that it's easy (maybe not even possible) to perform all three at the same time, and the documentation from SEGA doesn't really help programmers. SEGA really should've just released this hardware as a standalone console with all of the info, software tools, and coursework.

[@CharlesHepburn2]

This was excellent and taught me a lot I didn't know. I always wondered why the scaling and rotation was so choppy compared to SNES mode 7... I just thought they used a weak powered chip for it... didn't consider it was a bandwidth issue with the Genesis. I owned a Mega CD a year before it came out in the USA.

[@maroon9273]

Developers were using the Genesis cpu.

[@MaxAbramson3]

Most games used the 12MHz 68000 sub-CPU on the Sega CD for scaling, rather than the more powerful but poorly documented ASIC-DSP. It looks like some choppier games even just prescaled their tiles and loaded them right from the CD itself. What a waste.

[@davejohn3600]

Thunderstrike always impressed me. It seemed well beyond the Genesis' ability and pretty close to the 32X. Heck, it was more impressive than most 32X games.

Fantastic vid like normal. Great content, underrated channel. Keep it up!

[@litjellyfish]

Reason that the scaling planes are only 16 colors is the framebuffer they are copied to is just the tile ram for PF1 or PF2 And as each tile can only have 16 color that is what creates the restriction.

[@RetroSegaDev]

Thank you, Thank you, Thank you, Thank you! I've been meaning to do a video covering WHY super scalers are a pipe dream and you've explained it perfectly :) Scaling wise bog basic estimates updating the entire screen 7FPS PAL / 8FPS NTSC and updating half the screen 13 FPS PAL / 16FPS NTSC. Many factors could increase/decrease this estimate by a few frames such as: SUB CPU, ASIC use, etc, etc. The less unique tiles scaling on screen the higher the framerate... A few things you may or may not know: 0:32 - The Sonic CD bonus stage was recently hacked to run at a higher frame rate but the guy who did it removed the video from KZbin :( 5:12 - Batman & Robin was pushing the CD to it's absolute limit there was no more bus capacity left in the tank. 9:45 - Sarah Jane Avory has noted Jaguar XJ220 used the Sega CD CPU for scaling and not the ASIC.

[@Sharopolis]

Thanks for the interesting insight! I'd love to see the hacked version of Sonic, I wonder why he took it down? I actually attempted to message Sarah Jane Avory when I was researching this vid, but she never got back to me. Quite a lot of games seemed to stay away from the ASIC, it must have been hard to work with. The only documentation I could find about it was Sega's own docs from that 90's and they aren't great.

[@julianregel]

@@Sharopolis Not sure if you've seen it, but the Service Manuals for the MegaCD has a block diagram of the 315-5548 chip (referred to in the docs as the Gate Array, and commonly call the ASIC) and the graphics components is only a small, single block within the chip called the "Rotation Interface". The rest of the chip seems to be about interfacing with the various buses and the bus selector logic that allowed different components to access different memory at the same time. While this obviously doesn't translate to how much die space was dedicated to graphics, I thought it was interesting that the "custom graphics ASIC" does a lot more than just the graphics. Great video btw, really interesting. Thanks!

[@MaxAbramson3]

@@Sharopolis Yeah, the tech documentation from SEGA not only explains very little, but provides few code examples and is partly in Japanese! No wonder the Sega CD saw so few arcade superscalers. SEGA should've just made the original Megadrive with the 12MHz 68000 and 128KB of RAM and VRAM. Scaling and rotation can be done in software if you have the horsepower to do it (like the 32X, btw). There'd be no need for the Sega CD had they gone this route... unless you REALLY have a hankering for those s***y FMV games.

[@MaxAbramson3]

Also, the data transfer rates (according to Tech Specs posted on Sega Retro) show the same 6.25MB/s and 1.34MB/s during active display as what you could get from a cartridge ROM. But only 128KB are accessible at one time, you say? Yes, but that's one megabit, plus the 64KB in VRAM and another 64KB in RAM, more than the assets that would be found in a single stage of a game.

[@cireza_]

Looking at Lunar 2 or Popful Mail videos would be interesting, because they are custom implemented. Robo Aleste uses several special effects, not sure how interesting they can be, but there is zooming, rain, lighting and probably others. Also worth noting are the SamSho and Fatal Fury ports. These are ports that retain the full size of sprites. I always found them interesting because even though you lose the ability to stream animations from the cartridge, you still get 786KB of RAM. So these games demonstrate the ability of the MegaDrive to handle pretty big sprites. Sprite size were always limited by the ROM size, otherwise the MD would have pushed much more impressive ports, so these ports are nice. Snatcher is worth mentioning for the sound design I think.

Sometimes I wonder what would have happened if instead of Sega doing the Sega CD and 32X add-ons had they stuck to their tradition of creating an all new platform that's backwards compatible to the last would it have fared better with consumers? But then again no companies were thinking about a 3D ready consoles back in 1991 when the Sega CD was developed. But even had they released this mythical system in 1993, Sega would have felt the pressure by both the Playstation and Ultra 64 being announced by early 1994 anyway causing them to move onto something like the Saturn.

[@Anonymous-oh4xw]

Except Atari, they did thought about making a 3D console with the Panther, which would be dropped in favor of the Jaguar in 1991 (ironically the year the Panther was supposed to come out).

[@casanovafunkenstein5090]

Part of me really feels like it would be interesting to see homebrew developers mess about with the 32XCD format. I know that the 32XCD is possibly the least practical platform in real life, but if you're emulating the ROM I think that you could have some fun pushing the limits of what such a weird piece of hardware could achieve in theory. Maybe you could use the FMV codec as an animated background layer with the Mega Drive and 32X freed up to display more complex sprites in the foreground and supplement audio coming from the CD

[@MaxAbramson3]

Actually, there were, IIRC, five Sega 32X-CD games, all of which were upscaled Sega CD FMV games showing off how much bigger and better the video could be using the horsepower of the Hitachi SH2. That system was hard to push to its limits, too, but at least SEGA would've had something out on shelves and getting pushed to its practical limits a year before the PS1 came out. We've talked about making of version of Doom Resurrection for the 32X CD, perhaps moving all of the music and sound effects to the Sega CD to free up the 32X for pure rendering and a higher frame rate.

"Criminally underused" is right. SEGA of Japan's decision to release the 32X and ditch the Sega CD--after we'd paid $300 for the addon--is what drove off the company's loyal enthusiasts. Every salesman working at a game shop made like $6-8 bucks an hour, and SEGA just throwing your money away on two underreported add-ons was a harbinger of things to come. And SEGA screwed over 9 million more with the Saturn and another 9 million suckers with the Dreamcast. A few fantastic M2 titles showed that SEGA could've carried their fan base to the late 1990s with the Sega CD alone.

[@MaxAbramson3]

I didn't mean to come across as mean spirited. However, I shelled out $229 for this beast and never saw a single TV ad showing the Sega CD's powerful 3D capabilities. Not one. And some gamers spent $300 for this and never got anything better than another one of those lazy ports. Why not at least bring over the arcade backgrounds for Golden Axe and others? Why not add a bit of scaling to Streets of Rage, or improve the ground and scaling/rotation of enemy planes in After Burner?

1:45 The time traveling in Sonic CD was literally just a palette swap of the same stage graphics which means it takes close to zero memory to pull off and could be done on a cartridge. Most of the extra space went to the CD soundtrack and intro FMV. Even the Mode 7ish special stage was only enhanced by the Sega CD. The base Genesis could have pulled it off with a lower res ground and choppier frame-rate. That's what the Sega CD should have been focused on.... scaling and rotation effects in games. Arcade fighters/beat-em ups/racers/sports titles with these super-scaler effects should have been the main focus for the system. That.... lack of 256 simultaneous(15-bit) color.... and not making it a stand-alone and still backwards compatible system were it's 3 biggest mistakes. I really wish Nintendo would of made a Nintendo Super CD or gave the N64 4x CD-Rom drive that would have been amazing.

[@greyfox1127]

So many brilliant games on the Mega/Sega CD. It really is a much maligned system considering how solid so much of its library is. It got a bad reputation due to FMV games but arguably these pushed the system too especially later ones that ran full screen with better frame rebates and more colours. Good list - I’d add Thunderhawk/Thunderstrike which while limited to less colours had smooth rotation, lots of enemy sprites and foliage etc and tilted the landscape - something more 7 couldn’t do. Battlecorps - again just really good use of the chipset Starblade - it’s a brilliant conversion considering the source material. Also - arguably the 1-on-1 fighters such as Eternal Champions, Faral Fury Soecial and Samurai Shodown considering the memory limitations and bandwidth issues. Pretty solid all round. Good video though. The system had some brilliant games if you delve into the library including ones that weren’t just ports of the cartridge version - Terminator CD or Shining Force CD (remakes of the Game Gear games) and Jurassic Park for example or were exclusive or made for the system - Keio Flying Squadron, Snatcher (in terms of an English release) , Cobra, the Core games, the Lunar games, Final Fight etc magnificent oddities like Panic/Switch etc or were upgraded ports of the cartridge version such as Mickey Mania, the Ecco games, Eternal Champions (effectively a sequel really) Batman Returns, Cliffhanger etc

[@acem7749]

The stamps thing blew my mind... 1st time I heard of it . Also how the Sega CD pushes the images to the Genesis vram limits for frame rate issues.. I swear some scaling games are smoother than 20fps.. but it makes sense now..

[@MaxAbramson3]

The Genesis Video Display Processor just displays the sprites in its 64KB VRAM according to the contents of the Sprite Attribute Table, IIRC. A stamp map, according to the Sega CD documentation, just takes a large image array and uses the powerful Coordinate Conversion Function to scale, rotate, or warp these stamps at runtime. The Genesis VDP simply reads 128KB of that at a time (using the DMA/Blast Processing, I think) and displays that to the output. I haven't actually looked at the documentation in over a month, so I don't recall the exact details. However, contrary to what's been spread on KZbin, bandwidth wasn't really the problem, and the ASIC-DSP could scale massive sections of the screen and still keep up with a fairly high frame rate. That's why so many 3D games for the Sega CD look so damned good.

[@MaxAbramson3]

I just double checked the tech docs. The Genesis VDP uses the same DMA transfer from the Sega CD RAM as it does the cartridge and at the same rate.

[@fungo6631]

4:55 Ironically this is where the PAL Megadrive is better. It has enough bandwidth for 25 FPS full screen animation. If the Mode 7 part occupies half the screen only, even 50 FPS might be doable.

I think for the most part rather than actually pushed the limit of what the system could do most of these just utilised what it could do to a high level.

[@awesomeferret]

13:44 there's no way that's 15 FPS. Sure, the FMV might be that, but how can 15 FPS be that smooth? Look at the ships and the projectiles.

Oddly enough Jaguar XJ 2000 is software scaling. Per the dev it was faster to do in software per early tests and later discovered there was a mistake. Hardware should have been faster.. the final game uses software.

[@MaxAbramson3]

Most Sega CD games didn't use the powerful ASIC-DSP at all. It was too much to learn, poorly documented (with no examples that I can find), and few software tools were available, so everything had to be done custom in house. That's what killed development for the 32X and the Saturn. If SEGA had spent the same money marketing the Sega CD and developing software tools for it, we'd have seen limit pushers in 1994-95 that looked better than most PS1 launch titles.
