[@Astfgl]

Id Software's code from the '90s and early 2000's are some of the cleanest, elegant and most pleasant codebases to work with. I learned a lot about quality in programming from modding the various Quake games and toying around with their code. It's also made all of the spaghetti codebases I've had to work with throughout my professional life extremely disappointing. Id just set the bar so high for me early in life.

Let's spend an extra moment to realize how completely awesome John Carmack is for making it open source so incredibly early. That was radical, and one of the big moments in gaming history!

[@NicolaiSyvertsen]

Easy enough with such a self contained code base as Doom. Then game devs started to lean more heavily on middleware and releasing source code would be impossible. Unreal's highly polished but expensive game engine and SDK is largely to blame as well. iD software was never into engine licensing as much.

[@roberte2945]

​@@NicolaiSyvertsen I wouldn't say they were never into it. They licensed all of their engines up to and including id Tech 3 (the Quake 3 engine, which was used for a lot of games), but it's since died back. Now their engines are only used for other Bethesda developers, which is a shame.

[@samin90]

Radical in the most 90s sense of the definition

[@NicolaiSyvertsen]

@@roberte2945 I meant as part of the core business. If you intend to make money licensing your engine you polish the tools and make them very easy for other teams to use. Tools that are for internal use only tend to be rough on the edges. At least it was that way back in the 90s.

Because we were more forgiving of stuff like that back then. Look at the frame rate the early flight sims ran at. We didn't care, it was awesome. Doom on the SNES was a great idea though. A lot of people I knew back in the day didn't own a PC like I did, and hadn't upgraded to a 32-bit game console either, yet Doom was right there for them to enjoy.

It's a crazy world we live in. ZZT (1991) by Epic Megagames was supposed to have its source code released in 1997 also, but Tim Sweeney lost the source code and only released the game as freeware. Just yesterday, somebody reverse engineered all of the game after so many years of its release. The point you made in the video about it taking much longer to have builds of Doom if the code wasn't released is completely true. Finally, ZZTers can get it ported to Windows, Linux and everything else without emulators.

It's interesting to know that a fairly stock Amiga could have run Doom back in the day. I remember the kind of "heart break" I had when I read that Doom wouldn't work on the Amiga. Nice to know, many years later, the truth of it came out and that open sourcing the game has actually made it so much more popular.

[@daishi5571]

I think the problem was that when ppl said "Amiga" they envisioned only the A500 or A2000 which without some upgrade can't run Doom (after all the hardware was basically from 1985 in these models) New Amiga systems were more capable but ppl were blinded by the amount of product and news coming out of the PC industry that they didn't hear what was happening on the Amiga. It's also nice to know someone as smart as John Carmack can be very wrong.

This caught my eye too, and I think both would fit the sentence. From a technical point of view, using only current code without relying on anything undocumented and not taking advantage of compiler quirks, the source code remains valid source code to this day. From a human point of view, making the code simple, logical and easy to follow, keeping the distance to least used and hard to grasp language features and structuring the project right, the next person to look at it can actually get some meaningful work done. MVG said he created the Xbox port in a few nights, and I bet it wouldn't have been possible without both of the above being true.

yeah.. some scientists will manage to artificially create memories and dreams on a PC and then implant them as-is into a person. and then some guy ports doom to a human brain.

Watching gameplay, makes me want to play Doom, no matter how many times I've played it 😁

[@RegretMSTRPWN]

This is just another great example of how restrictions lead to the greatest pieces of art. The difficulty in making a game of this caliber definitely was a driving factor in making sure the code was as elegant and good to work with as it was

[@BusyMEOW]

I played your port on my modded Xbox, it came with MAME but I was surprised to find DOOM was there as well.. That was the first time I got to own and play a proper HD version of Doom as I only played it on my Snes or on my school's PC's 🙂 Thankyou, fellow Aussie.. I loved the Switch port too, how it updated to play proper widescreen.

Me: deprecated MVG: *depreciated*

[@Mecharuva]

I think at about 6:45 you were looking for the word “deprecated,” maybe?

[@Frostie3672]

I'm amazed how well the doom ports played on my Amiga, I was running the blizzard 1260 accelerator which obviously helped, think it was A-doom that I played, it was silky smooth. Quake played pretty well if I didn't have the game play in full screen, had to shrink it down a bit to get a decent frame rate but just the fact that you could play it & doom on the Amiga was amazing.

[@ChuckMoyes]

I ported Doom to Nintendo DS (with wifi multiplayer) back in the day! Brings back good memories, thanks for making this video.

[@GTXDash]

I would die for someone to do a decent port for the Saturn. Apparently the developer got the game to work at up to 60fps because he was utilizing everything on the board including both VDP chips. Unfortunately Carmack told him to not use them because they had the "unfortunate" side effect of texture warping. And so now it runs at the software level which results in an abysmal framerate. :( I would also like to see a good port for the 3DO as well.

[@JAGO_Tech]

Did you know Japanese framerates on SS port are better? Fun fact.

[@GTXDash]

@@JAGO_Tech That's what they said about Tomb Raider also, but they were also wrong. The Japanese version of Doom runs just as bad as the American.

[@JAGO_Tech]

@@GTXDash I've played 10+ hours of the US version of SS Doom. It's fairly choppy. I saw a comparison version on YT of JPN & it did look better. Not near 100% but better. I've also played through TR on SS & PSX. It runs fine on SS. The differences to PS1 aren't substantial. I'd say the PS models look slightly better due to shapes of polygons matching original development.

Omg That‘s Clint from LGR! Best crossover Episode everrrr

[@mrnelsonius5631]

I grew up during the age of Doom and Quake. It’s why I started building computers and tinkering with software, learning basic coding etc. There was an incredible ethos running through computer tech in that era and I feel lucky and to have experienced it but also sad about things currently. No company now would allow a full source code release of a technologically ground breaking product like Doom, just a few years after initial release! Carmack did that for the good of the medium, as a valuable tool for others to learn and be inspired from. It cemented Doom’s everlasting legacy and I still find it emblematic of a better time in tech when the medium itself invited and challenged the public to understand the tools they had access to on a deeper level. Computers weren’t just appliances, they were the instrument of the future.

[@linklovezelda]

Aw man, did you just say "depreciated"?

[@CanuckGod]

Noticed that too, I think he said that in another video as well. That was about my only criticism of the video, should have been deprecated. Otherwise, another great video MVG!

[@dustylamborghini3577]

Biggest mistake ever made: Underestimating the Amiga (!!!)

[@vapourmile]

LOL. Doom is shit on every kind of Amiga except the 68060 accelerated Amigas, and it wasn't available on the Amiga until 1998. Carmack was absolutely right: On the Amigas which existed at the time Doom was actually released, Doom would have sucked. The idea the Amiga was some kind of graphical powerhouse is total and utter fiction.

Fabien Sanglard's Game Engine Black Book series is fantastic! With the DOOM book, I'm a little disappointed that there wasn't more time spent on the engine (Fabien assumed you'd already read about most of it in his Wolf 3D book) and perhaps too much time spent on individual console ports (which were interesting in their own way, but dragged on if all you wanted to know about is the DOOM engine internals and not how each console's hardware worked). For a quick comparison (not commenting on quality of content, just numbers to illustrate a point) the DOOM text was 423 pages and 139 pages (33%) are dedicated to the engine, while the Wolf 3D book was 311 pages and 152 pages (49%) were about the engine. Both were still incredible reads and highly recommended. I am very grateful to Fabien for putting both together as this is exactly what I've always wanted and never expected to get. (I became a programmer because of DOOM, but understanding the engine always seemed just out of grasp.) I couldn't put either book down and read each in a single sitting. Fabien also has a great blog that I highly recommend (fabiensanglard dot net).

[@Ziimbiian]

I have yet to see a GOOD DOOM port for the Sega Saturn.

[@Ziimbiian]

@referral madness You're wrong. Saturn Doom wasnt made by Sega. There is a prototype that is lost out there who plays Doom with GPU acceleration, it has texture warping but it ran at 60fps.

[@Juanknes]

@referral madness It can run Hexen at good speed. The Doom port was a disaster...

Hi - I'm the author of Chocolate Doom. It's always great to see more people talking about the Doom source code and I highly recommend it as a fun codebase to hack on and experiment with. Also another +1 for Fabien Sanglard's fantastic Doom Black Book that I also helped out with. The PDF version is packed with fascinating stuff about the Doom engine and will appeal to anyone who's curious about how games like this were written.

Brilliant video! Would you want to do a video digging slightly deeper in to working with the original xbox to the switch, not a training video but more of an appreciation of what you ha e done. Really enjoyed this anyway.

I've been on a 40k binge lately. You don't want to know how many Space Force ads I've been getting.

[@angolin9352]

It's actually not. All the recent Doom/Animal Crossing memes have created an association in Google's ad AI. If you have been participating in this, Google knows and will serve you even more Animal Crossing ads. I miss the days when the surveillance in 1984 seemed like an exaggeration of a possible future. Nowadays reality is worse.
