The amount of versatility in the Megadrive architecture and the power that can be extracted from it never ceases to surprise me. I look forward to seeing the release of all these developments, and keep hoping for the day someone cracks open the 32X CD nut.
@@inceptional well, first of all I'd need to know what it is about. It wouldn't be wise to blindly download something from someone I don't know, while simultaneously not knowing what it will be about.
Amazing that 3 decades later, people are still developing for this console and constantly innovating, doing things that were previously thought impossible!
Using "mode 1" to utilise the Mega CD hardware is such an exciting prospect. It would come in very handy for my SotN game too (extra CPU grunt, scaling, PCM sound channels etc). Do you know why using the CD CPU results in a 300% boost to the FPS? That sounds a lot, I would have expected maybe only +50%. Are both CPUs being used in tandem now, or does the MD just kick back and relax? It would be great if one day the Mega CD's mode 1 could provide a boost to any MD game, much like the PS4 Pro did for regular PS4 games, although I'm sure things aren't as simple as that.
My understanding from Sik is that he's moved the renderer to the MCD sub CPU to deal with the drawing, while the MD deals with the rest. He's using mode 1 with the MCD in 1M mode. In this mode the word RAM of the CD is split into two halves to enable streaming tile data. I talk about this in Secrets of the Sega CD part 1.
Shifting the renderer frees up a lot of CPU time I'd imagine. It's gone from 10 FPS to 30 FPS from what I gather. You could use it for effects but I'm not convinced the second CPU or ASIC would give you much other benefit.
Yeah, they're running in parallel. The CD CPU is _only_ running the renderer without any of the game logic etc. eating up CPU time (which is kept on the MD CPU), so the actual boost is way more than the clock speed increase would imply.
The amount of love the MD is getting at the moment is warming. I thought gasega had long abandoned those racers as just Proof of Concept videos. If there is to be end products that's wonderful! Nice to see all this cool stuff covered in a single video. I need to be getting back to checking Sega-16 a little more often!
Poor documentation or they were but only in a limited number of games. The CD stuff was probably to do with them pushing the CD format. A cart game that required the CD might have been confusing to the public and been seen as a negative towards the CD format lol
There are many reasons, but they boil down to three: 1) They had to adhere to deadlines. 2) They did not have 30 years of history and investigation to draw from. 3) The development environments are much more refined now.
People talk about the SotN demake being difficult to make, but it's these people doing 3D stuff who are really playing on hard mode! At least the Castlevania game is 2D. Are any of the ones you feature in this video made with SGDK, or are they all using good old assembly?
To your credit cramming SotN into VRAM isn't an easy feat. The 3D stuff here is predominantly assembler with the exception of Erik's engine which is a hybrid mix of SGDK, custom C code and Assembly. I apologise for not featuring your work yet! I felt you didn't really need much of a push right now given your viewing figures are phenomenal. Also it's kinda ironic as your channel seems to be where a lot of my viewers come from 😂
@@RetroSegaDev That's ok, I understand. The attention from the SotN project is something of a mixed blessing, as a part of me would have preferred to have kept more of a low profile during my "learning phase". Thankfully pretty much everyone seems on board with what I'm doing and are being very patient, so I seem to have explained my situation quite well. Once I get a little more experienced at youtubing and have a decent audio set-up, then I would like to do some videos similar to this one as well. I'm also going to do an FAQ video later this year. Lot's of people have been asking "Why don't you utilise the 32X/Mega CD?", but of course it's not so easy. If you don't mind, I'd like to link them to your Mega CD videos rather than try to explain it myself. BTW, that Resident Evil game is an SGDK one, right? I suppose isometric is just another form of 2D, so no fancy assembler stuff is required.
Sure feel free to link. Looking forward to you getting your mic setup and doing some other stuff 👍 I have seen the resident evil game and I do think it uses the SGDK. I haven't looked to see how they're doing view wise. It got a fair bit of momentum when it was first shown.
@@RetroSegaDev I heard they asked Capcom for permission to release it as an official game (brave move, certainly not something I'd dare do with Konami), but were rejected. I think they are going to convert it to an original IP. I hope they carry on. A survival horror on the MD would be nice.
wow, if you hadn't have said anything I would have thought that star fox footage was genuine snes. Also as good as that first game looks I cant take it seriously because the way the hands move on the controls reminds me of envirobear 😅😅
"Mode 1", interesting... So a cartridge game could use the MCD's CPU. Could it also use the audio from a CD at the same time in that mode? And that Starfox demo on stock hardware, what an achievement...
I believe krikzz already did, but it was extremely slow (multiple seconds per frame). Doom is a bit beyond what the genny can do, but maybe with a lot of simplification and really hardcore optimization....

OBS video capture it and then upload it to your channel 😉
The homebrew scene is fantastic...It'd also be great to see new soundrivers for the YM2612...To push it to the limits!

Oh wow great to see you here Sik! And thanks for confirming things.
@@RetroSegaDev Thanks, that's very interesting
It's fantastic to see that the SegaCD is being used for homebrew. OMG, don't tell me that a stock Genesis can do what a SuperFX chip can!
The genesis homebrew scene is getting pretty nuts
It's only just getting started I think!
Pigsy's work is so well covered I don't need to make people aware!
@@RetroSegaDev I'll drink to that.
It's nuts seeing what the Mega Drive can do. Also can I just say that I love your outro by the way
Lol everyone keeps giving my outro love at the moment! Thanks!
It takes time for a system to be pushed to its limits. Usually years later after its lifespand.
The amount of love the MD is getting at the moment is warming. I thought gasega had long abandoned those racers as just Proof of Concept videos. If there is to be end products that's wonderful! Nice to see all this cool stuff covered in a single video. I need to be getting back to checking Sega-16 a little more often!
Nooo never abandoned!
Yea same here. I thought they were just tech demos.
Dude this shit is incredible. The Starfox one looks exactly identical to the Super Nintendo version. That's real time?! WITHOUT SUPER FX?!?!?
Yup real time based on the models extracted from the SNES game!
Could you imagine how this would blow up the school yards if you could send somehow this code back to the 90s?
Pretty cool stuff. Very interesting how close the Genesis Star Fox hoembrew looks to the snes versioj.
Isn't it just!
Keep these coming! The only channel I have alerts set for
Thanks Dave!
Imagine seeing these in development back in the day....
Great news especially for the sega cd. Hopefully we will see scaling/3D homebrews and arcade classics being release to the sega cd.
Great video. Short and sweet!
Star Fox is looking pretty good. Hope to see it fully implemented in the mega drive.
Genesis does what nintendon't.
Unlikely as he doesn't want Nintendo chasing him
@@RetroSegaDev he could implement his own stages and enemies. And call it star hedgehog.
Lol he might but things would need changing up a bit!
I love the homebrew indie scene. Arkagis escape looks amazing!
Wow haven’t seen anything like those mode 7 games before. Thanks for sharing. It’s a slow burner but the MD will eventually win the console war 😂
@@rustymixer2886 true. You can’t have Star Wars without the Empire.
Interesting stuff, Matt! 🤓
I ask myself why such "miracles" weren't done 30 years ago...
Poor documentation or they were but only in a limited number of games. The CD stuff was probably to do with them pushing the CD format. A cart game that required the CD might have been confusing to the public and been seen as a negative towards the CD format lol
There are many reasons, but they boil down to three:
1) They had to adhere to deadlines.
2) They did not have 30 years of history and investigation to draw from.
3) The development environments are much more refined now.
@@Myako also, the advancement of software tools.
Yep, these are the three most important factors. Emulators, no deadlines, much better hardware to develop on and debug with.
Thanks for the info
Se ve espectacular

That's a shame and I'm amazed they asked! I did say at the start they needed to make their own IP. Hopefully it turns out well!

envirobear? What's that :D

Indeed Pier Solar used the CD audio remember 😉
@@RetroSegaDev Thanks! I just wasn't sure as mode 1 seems hardly used.
@@jbmaru I wonder why Mode 1 wasn’t known or used by Sega.
I wonder how long until some madlad gets Doom working on stock Genny: )
I believe krikzz already did, but it was extremely slow (multiple seconds per frame). Doom is a bit beyond what the genny can do, but maybe with a lot of simplification and really hardcore optimization....
