3D Sega Homebrew: Sega Genesis & Mega Drive, Sega CD & Mega CD and Sega 32x

Never! 😆

Love seeing people develop on and push the genesis/mega drive to it's limits. Seeing wolf 3D running on the genesis/mega drive years ago was a treat.

There's lots of untapped stuff. Hopefully Gasega68k will return eventually 🙂

@@RetroSegaDev indeed, I do hope he's doing well. Haven't really seen an update from him in quite a while

[@juststatedtheobvious9633]

@@RetroSegaDev Speaking of untapped potential, it's a shame nobody's working in wireframe. Just look at Star Wars on the X68000, and imagine that kind of engine handling a Wipe-Out style racing game, or an FPS style approach to Dungeons of Daggeroth. You could get amazing results if you sacrifice everything else for performance.

[@st1ka]

Man these look great. I didn't know Plutiedev had moved his game to the Mega CD though.

[@RetroSegaDev]

He hasn't! You can potentially use the cart version to take advantage of the Sega CD CPU like Paprium does!

Clarification regarding the new game by the Arkagis Dev (plutiedev). He's looking to add acceleration via the Sega CD Sub CPU in the cart edition of the game. This hasn't yet been confirmed as a definite feature. Another point I need to make is 32x Doom port uses "Calico" Doom not "Coleco" Doom 😁

[@philmuller-geib3361]

So that means that the MD & SCD can work in tandem? Let's say, a game relesed via cartridge can use both MD and SCD processors, together? Well, that would indeed be BLAST PROCESSING :-) - I once read that games released for the sega cd could also use the MD's processor....That'd be a total of 20.1mhz!

[@RetroSegaDev]

Using both CPUs together isn't an easy feat and comes with a bunch of complexities. I'm not sure what the plan is with this PlutieDev may just be using the MCD CPU instead of the MD CPU via a cart game. I guess we won't know unless PlutieDev decides to use it 🙂

[@BubblegumCrash332]

Has anyone ever been able to program on the Mega cds ASIC for hombrew. If love to see what devs could get out of that thing. Sprite scaling was criminally underused on the system

[@DeadnWoon]

I hope and believe and want that in a few decades we all return to good old 16bit consoles. New consoles will reach the peak one day, the peak that will mark the end of all humankind.

SVP Virtua Fighter would be a neat showcase. The Genesis hardware can handle everything but the fighters themselves, even a little mode 7-esque action is possible on a stock Genesis.

[@maroon9273]

Also, star wars arcade, wing war, doom (sega cd svp), zaxxon motherbase 2000, stellar assault, knuckles chaotic and the cancelled virtua hamster. Also, a cut down version of Daytona and virtual fighter 2.

[@AlexvrbX]

@@maroon9273 The SVP is only really good for pushing flat (untextured) polys. It's the chip that was in Virtua Racing for the Genesis. So SOME of the games you mentioned would be good candidates, and some would not. For example anything 2D is a no-go, and Doom would also not be good, due to the lack of texturing. In the case of Doom though I know you mentioned the Sega CD... there's no SVP in the Sega CD, maybe you meant the ASIC chip? You could absolutely use the Sega CD to handle certain things - all the sprite scaling could be done on the ASIC, CD music, and the extra grunt from the second 68K plus a bunch of RAM. If you made it a combo cart/CD game I think it's doable in a cut-down fashion even with the limited RAM. But the SVP is useless for Doom unless you want Doom to be a bunch of blocky flat polys like Virtua Racing and use a custom engine.

[@maroon9273]

@@AlexvrbX I was talking about a cd/svp cart combo game. Snes doom did used texture for background walls and flat shading for the floors.

[@pabloignacioscaletta]

YAY! A Virtua Fighter port would rule, and even a true 3D port of Virtua Fighter 2 with the intact roster (the official game lacked Leon Rafale and Shun Di and gameplay and graphic-wise it was a standard 2D fighter.)

I'm a big nintendo fan, but I love the genesis' homebrew community. I whould love to see stuff like this done on the snes when the snes homebrew community gets bigger.

[@acardboardbox3897]

@Daniel Long Well the snes' hardware is more powerfull than the genesis, so maybe there is no interest on a more powerful console.

[@jc_dogen]

@@acardboardbox3897 it's more powerful in certain ways but sorta less flexible and more rigid. best example is the sprite engine which is a lot jankier on snes than genesis

[@lustechsource5197]

Awesome video. These are some very interesting projects you talked about. I'm really happy that the Sega CD and SVP chip are being worked on.

[@RetroSegaDev]

I'm very excited about the SVP work. It's never been exploded properly so I do wonder if it could reveal some interesting things regarding polygons games on the MD :)

[@brainbeatuk]

Is there any native trackers that support sega cd

[@maroon9273]

I'll love to the svp and sega homebrew software will push both hardware to its limits.

[@gaving.griffon2703]

Imagine if there were Sega CD games that used the svp chip.

[@AlexvrbX]

I'd settle for more Sega CD games that actually taxed the Sega CD's faster 68K, as well as specialized ASIC... let alone used them well (and in tandem with the Genesis' own capabilities). There were a good few, of course... but a lot of the SCD titles were FMV games or games that are basically Genesis titles with a CD audio soundtrack. The SVP aside, I have often felt that even a standard cart could have been used to accelerate loading of common assets for the Sega CD. For example in an RPG like Lunar, you could store most battlefield assets and other common sprites to massively reduce the time needed to hop into or out of fights.

[@madhatter8508]

I'd rather see CD 32X games. I think it could handle a basic car combat game like Twisted Metal, or a simple texture mapped racing game like Ridge Racer. I don't think it could handle an arcade-accurate port of Daytona USA. Would it be feasible to use it somewhat like a Saturn, where the Sega CD renders the floors as textured bitmaps and the 32X draws polygonal objects on top of it? If I am correct, which I'm probably not, the Sega CD 68K can run game code, the Genesis CPU can handle the DMA to VRAM, the ASIC can render the floors, and maybe both 32X CPUs can draw texture mapped polygons over the Genesis/CD background layers. Both CPUs working together (if they can) should be able to draw texture mapped, gourad shaded polygons comparable to the performance of the 3DO.

[@maroon9273]

I'll love to more of the sega cd and svp software homebrews.

[@PrinceLucifer1986]

I've just got a 32x. I really hope there will be some homebrew games in the near future for this, the Mega CD as well. I've subscribed in case you get any updates on this 😁 I feel we didn't get to see the full potential of Mega CD, and 32x.

[@MegaCallum10]

Imagine if the 3D demo used both chips of the 32x. Wonder if it would get a speed boost. But yeah, it is interesting the architecture of both the 32X and Saturn, they used chips from a similar family but as a result also made both systems difficult to program for.

[@RetroSegaDev]

Both 32x CPUs? If that's what you mean it does now.

[@xXBeefyDjXx]

As someone who has faithfully modified the whole stack (Mega CD 32x!), it's a shame that the 32x and Mega CD didn't get much love officially. Brought here by google, this was a great insight to the future of the MD Homebrew Scene and I am totally looking forward to it! I can only hope that in the future, people start tinkering with the idea of proper Mega CD 32x usage. If we can achieve great 3d rendering with the 32x on it's own, imaging what having the extra power of the Mega CD bulked on top of MD + 32x could do in theory! Gotta say though, I certainly don't envy anyone attempting such a challenge on one of the addons, yet alone both at once. Spaghetti junction I presume.

[@RetroSegaDev]

Mmm it's extremely limited! No one has ever attempted it because there are a number of issues! I'll cover it eventually 😁

I've seen it but don't think I've played it. I actually know someone who was editing the ROM to optimise it! Small viewing window but really not bad for what it was at the time. I'm guessing you've played the wolf 3d port?

[@MasterNinjaKF]

Amazing content!

[@EbenezerScroogeMcDuck]

some of us be confused of what the 32x actually was.. watching some vids about "all 32x games", it sounds like these games were literally just sega genesis games that used the 32x as offload (or just an extra resource rather than the 32x actually being THE console (and using the genesis as a video output only). were there any games that only used the 32x "period"? or were games based on the tech demo even possible? (some of the tech demo bits looked like starfox 64). heck, could tomb raider have been possible on 32x in a lower res version?

[@RetroSegaDev]

The machine offered extra sound and an extra layer of graphics. The graphics layer was drawn by the 32x and could appear above or below graphics output of the Mega Drive. You could ignore the Mega Drive graphics totally and render everything via the 32x layer. You wouldn't see Tomb Raider ported as it hasn't got the RAM to handle it but something Starfox looking is possible as it works to the systems strengths.

[@viciious1234]

A watered down version of the original resident evil with would be possible. Tomb raider - I don’t think so.

Watered down Resident Evil lol Makes me think a demo of that would be negatively received as most would comment it looks awful compared to the Playstation 😂

Doom just used the one CPU for rendering. I'm yet to see anything documented of a game released using the 2nd CPU for rendering maybe one day someone will! Darxide or Metal Head maybe?

[@neilmclean1527]

@@RetroSegaDev That's crazy! You'd think Sega themselves would release at least one title that shows what the system can do - ideally at launch. Same story with the Saturn.

[@RetroSegaDev]

Yes very much the same story as with the Saturn. Although the 32x hardware was much more simple. Although with so little RAM it's hard to write duel processor software Unfortunately the system wasn't around long enough to see it reach its potential. Second gen 32x games would have been really interesting I think!

[@pweddy1]

The Sega CD is particularly interesting to me because it adds a second 12MHz 68000. This should allow dual CPU code to render 3d algorithms significantly faster.

[@RetroSegaDev]

Unfortunately it would be difficult to do dual CPU processing as the processors don't have direct simultaneous access to the same RAM but the Sega CD CPU can act as a sort of rendering GPU instructed by the Mega Drive.
