[@ireneparkin3360]

Fun fact:- if you type any of these codes into the original version of DooM 3 on PC, a message appears saying "Your memory serves you well."

[@user-tm3fz7qx3s]

Wow.

[@JacOfArts]

I remember seeing a video that showed that, it’s amazing

[@hangemhighhilton]

That was like the very first thing I did when I fired up DooM 3 for the first time. I barely got off the fucking ship and was instantly all like "iddqdidkfaidclip". XD

[@thegamingnator]

another fun fact if you type the same two cheats into Heretic this is the messages you'll received IDDQD - Kills the player. Originally the Godmode cheat in Doom, it is a joke by the developers by making it have the opposite effect in Heretic. When entered, on the screen is displayed: "Trying to cheat, eh? Now you die!" IDFKA - Removes all weapons and ammo the player is carrying, except for the staff. Any weapon that exists as a map item can be regained by picking one up, but the Elven Wand will be lost for the remainder of the game session. It can, however, be recovered by using the "rambo" code. Just like the 'iddqd' cheat, this code is from Doom. In Doom, it gives all keys, armor and ammo. In Heretic it does the opposite by taking them all away. The screen says: "Cheater - you don't deserve weapons!"

[@eur0be4t3r]

And it's an easter egg in DOOM 2K16

[@richardjohansson9749]

I remember being like 9 years old and typing IDKFA in Mechwarrior. Result? Instant-death and a message something along the lines of "This aint Doom, bud"

[@CodexShow]

Good to know! I never played much Mechwarrior, but I will have to check this out!

[@Cunnysmythe]

In Heretic it took all of your weapons away saying ‘cheater... you don’t deserve weapons’ IDDQD killed you instantly- ‘trying to cheat, eh? Now you die!’ Still had its own cheat codes of course

[@mjen]

Didn't one of the cheat codes turn you into a chicken?

[@gnarlestongnu637]

@Matt Jensen I think that was in Heretic or Hexen

[@Cunnysmythe]

Matt Jensen yeah, it had a turn enemy into chicken spell and a cheat that did that to you. Think it was a legit cheat as opposed to a backfire one though

Who actually plays the steam version of doom? The only reason I own it is to get the .wad file to use in an actual source port.

[@CodexShow]

Good point! I suppose that particular line was directed toward mainstream players who were turned onto the franchise by the latest installment :)

[@slipangle3027]

Fair enough. I always recommend people use something like GZDoom though for its quality of life improvements, but the original exe still works fine in dosbox.

[@davidkirinic9463]

GZdoom changes way too much for it to be really plausible imho

I can't get my original Doom cds to work on windows 10. :(

[@ESPViper100]

"DOS itself actually still plays a role on Windows today. It's just has been renamed to Command Prompt." That's just wrong. cmd.exe is not MS-DOS! The command prompt is merely a command line interpreter. MS-DOS is a complete operating system. MS-DOS and the Command Line are completely different things.

[@XRADU97]

[@sheridanrathbun]

Modern windows shares no heritage with DOS. The last version of windows to be based upon the MS-DOS architecture was Windows 98; WinNT was effectively a total rewrite of the kernel. The similarities between the command-prompt and DOS prompt after that are purely superficial.

Doom is the most important PC game of all time. It single handedly popularized PCs as gaming platform

[@CodexShow]

Couldn't agree more!

[@BlindMelonLord]

Daniel Scott in my opinion, and some other people, Wolfenstein 3-D helped get the FPS genre off the ground, but Doom popularized it, and helped it become what it is today. for crying out loud, if any other first person shooter games came out at the time of the original Doom’s existence, they were called Doom clones.

[@sophiacristina]

Yes, it alike Mario Bros for PC. All kids of 90's that had computer played Doom, Warcraft (aka: War), X-Com, Lotus Challenge, Nascar (Spent lot of time in its cars editors), Day of Tentacles, and some others... Agree with Jesse Schmies, just to note, Doom had this falling feature and floor and ceil sizes, flying objects and other things, this made the game have a lot of new parameters and much things to explore, making people raising their eyes for Doom more than they did for wolfenstein, there is an interesting part of the wiki article: en.wikipedia.org/wiki/Doom_(1993_video_game)#Reception After adding jump with zdoom, the game became "limitless", as we can see in the modding community of Doom. Also, it had multiplayer and created the term "deathmatch", basically, its the precursor of this multiplayer fps "addiction" we have today that got consolidated after quake, half-life and then, a little later, Counter-Strike, that appeared in the "golden era" of FPS.

[@OlviMasta77]

Doom and Quake were beyond revolutionary in so many more areas then Wolf3D, even as lovely it was.

[@RFC3514]

Actually, Tetris did that. Doom was far more popular with teenage boys, but Tetris was played in every office (where the vast majority of PCs were at the time). Tetris is also (by far) the most sold game ever, across all platforms (in addition to being the most pirated).

[@mephInc]

I'm so glad I was a teen when Doom came out. Those were the good old days... You'd buy a video game, and you'd get the entire game. The WHOLE game. It really irks me to see the garbage that a lot of these companies release for $60 a piece that barely function. Then they have the balls to sell "expansion packs" and include microtransactions. Do people still have LAN parties? I really miss those. Sure, it's fun to obliterate your enemy online, but nothing tops clobbering them in a house full of people and yelling "since you're dead anyway, can you grab me a Jolt from the fridge?"

[@CodexShow]

That's awesome! I honestly wish I were just a few years older when the game came out. I was barely 6, but I remember getting my dad's permission to download it from some FTP. Sadly I never played a lot of deathmatch, just coop over modem with my school buddies. More or less every day we would mix up who would play with whom, and a few of us had multiple phone lines which made things super interesting! I've actually been to a few LAN parties with some pals up here in Toronto, mostly to play UT and Diablo 2 and stuff like that. Most of my LANning was done in high school, playing SOF2 and Counter-Strike. Those were the days :)

[@RobNomad]

To be fair there's ultimate doom with a fourth episode and i don't complain about it

[@baladar1353]

I was 15 when it came out. Since I live in central Europe, then we haven't had any sources to new games other than BBS-es and truck drivers who worked in the UK or in the US. Internet wasn't available, and if it was, it would be extremely expensive, compared to our wallets. But that time was much better than now, there weren't complete asshole trolling 9 yrs old fucks and such things that are "normal" today. Of course there were some idiots and snowflakes, but we could handle them as they deserved. There were no beaten up teachers, parents were parents, not humiliated slaves. Back-chatting kids were punished, and treated as children. Ok, I went too far... Oh yes, I almost forgot... Boys looked like boys, and girls looked like girls, not the opposite. There were no such shit like today. I wish I had a time machine to go back and stay there.

[@argosharru]

Sometime in the 90s my friend told me that a friend of his has a book with Doom codes. We wanted us some codes, so we trekked across the town to that friend's house. Being two geniuses, we didn't think to bring a paper to write them down, nor to ask that friend for it. So, we asked for two codes, with the goal that each of us remembers one and we write them down when we get back to my friend's house. So, we went, repeating these strings of letters over and over and over. And that's how I must be the only one whose first thought when hearing "Doom cheats" is not IDDQD nor IDKFA, it's the bloody IDSPISPOPD. Over twenty years later, you could wake me up in the middle of the night and I wouldn't struggle to remember IDSPISPOPD. IDSPISPOPD. Eed, spiss, pop'd.

[@CodexShow]

"I-D-Spiss-pop'd" is exactly how I've pronounced it in my head ever since I read it back in the day. Thank you for sharing your story! It's definitely one I can empathize with - swapping save codes for NES games back before cartridges held any save data, eesh!

[@Cawshes]

Wtf is idspispopd

[@IanWatson]

While you said you'd cover what "degreelessness" meant, you (and John Romero) instead answered what the "DQD" meant. It took me looking it up elsewhere for me to finally get it: For 25 years I thought "degreelessness" was the state of removing "greelessness," whatever that was supposed to be, like "degaussing" a hard drive. Employing the "de-" prefix to what might be a made up word. I feel like an idiot for not getting it sooner, but degreelessness is "the state of not having a degree," which obviously makes sense with the DQD part of the story. So if anyone else watching didn't grasp that, let my fail be your success.

[@CodexShow]

Totally fair Ian, thank you for clarifying! I'll be more specific with details like this in future episodes. :)

[@someguystudios23]

I thought degreelessness just meant insane or something.

"Don't worry, this isn't an audiobook ad." Kid you not, I was thinking exactly that and was about to roll my eyes. But you saved me from doing so. Excellent video. A friend and I were discussing these cheats not too long ago, probably a few weeks or so. What an interesting topic it turned into!

[@CodexShow]

Hahah! Don't worry, it's not my intention to throw in sponsors - I just want to get people psyched on classic video games! Thank you for the comment and the support Paul, stay tuned for more stuff!

[@Scrotumdepoulpe]

Fun fact : As a french, I use a "AZERTY" keyboard. So, when I was playing DOOM, I had to type "I D D A D" instead of "I D D Q D". For a long time, I thought that this cheatcode was reffering to a "daddy". :\ Note : even in the official & non-official DOOM guides, all the cheat codes are written using the AZERTY keyboard. IDKFA becomes IDKFQ, etc.

[@CodexShow]

That's really interesting, thanks for letting me know! Very cool that even game guides had the AZERTY keyboard equivalent. I'll see if I can work this into a future episode :)

[@lauretivan6231]

je confirme... souvenirs ^^

[@watchmakerful]

It's very strange, does Doom recognize physical keypresses and not characters typed on the keyboard?

[@Scrotumdepoulpe]

With an AZERTY keyboard, the "A" replace the "Q". So, when you type "IDDAD", that's like "IDDQD", because DOOM recognize your keyboard as a QWERTY. So, there is'nt any difference. It's like using a QWERTY keyboard, with a game recognizing it as a QWERTY, but with an "AZERTY physical layer" on your keyboard. In fact, in France, when you type "IDDAD", it's like typing "IDDQD". You can easily verify that by saving your game : if you want to name your save "IDDQD" you have to type "IDDAD", 'cause the "A" become a "Q".

[@earthclad6833]

[@rmoog1019]

2:18 @Codex that is not true and I'll say why. DOS is in no way a part of Windows since 1993 and definitely not since 2001. Let's remember that Windows started as a graphical environment for DOS. In 1993, Microsoft created a new beast called Windows NT, completely independent of DOS. It was mostly intended for the enterprise market and it gradually drew design inspirations from Unix. To make the difference even more obvious, NT was using its own kernel instead of relying on that of DOS like 95, 98 and ME did. The command prompt we see nowadays is just a shell for running Batch commands and that's what it always has been. Nothing more, nothing less. Batch as a shell is implemented in DOS, Wine and Windows. The reason why MS still keeps it around is to support legacy scripts that didn't migrate to PowerShell. The most obvious giveaway of Windows NT not having DOS is the fact you can't run certain DOS software in NT-based versions of Windows, despite Microsoft's best efforts to provide compatibility layers. Best I can think of is SimCity 2000 and Quake. These games are written for DOS with absolutely no memory management in mind, so the NT kernel will rightfully stop them as they will try to access memory that was not provisioned to them by the kernel in a legitimate manner.

[@CodexShow]

Thank you for the comment! Other people have brought this to my attention, honestly it was just miscommunication on my part. I'm totally aware the Command Prompt in Windows is not an actual operating system, but for the sake of simplicity I glossed over the details and ended up misrepresenting DOS a little bit there. I appreciate the detailed notes! I'll keep this in mind going forward :)

[@rmoog1019]

You're welcome :) Admittedly I made the same mistake until I started researching OS design. Onto the video at hand however, this is really interesting and well researched. You've answered some questions I wondered long ago.

[@watchmakerful]

>>DOS is in no way a part of Windows since 1993 It was up to Windows Millennium. But yes, not in NT based systems.

[@Akriashi]

To further pile on to that, DOS was part of the 9x Windows OSes.. as a built in compatibility layer. the 9x kernel ran the MS-DOS kernel in a VM to handle things it could not, such as MS-DOS drivers, and like wise ran every app in it's own VM container for this cross-support (so say a Windows App could have its System call handled by DOS because it's calling out to a device using a DOS driver)

[@YoutubePremiumMem]

We know what he meant. The command prompt just provides the same syntax and look of ms dos. OS X had terminal and so forth.

"DOS itself actually still plays a role in windows today, it's just been renamed to Command Prompt" Nope, contrary to popular belief, DOS and the Command Prompt are not the same thing, the last version of Windows with the DOS Kernel was Windows ME (In which it was combined with the NT Kernel that current Windows OSes use), all current versions of Windows use a different kernel, hence why DOS games require emulation or a source port to run on current Windows versions. That being said, good video.

It's insane how I am remembering these codes as you bring them up! It's been so many years now.

[@JamesLewis2]

DOS is the inspiration for the Windows Command Prompt, but it does not have any role in 64-bit Windows (which most installations today are), and even in 32-bit versions of Windows, a subset of DOS functionality is provided by the NTVDM (NT Virtual DOS Machine, where NT stands for New Technology, for the non-DOS-based Windows versions first released for enterprises in 1993); the last version of Windows to be based on DOS in any way was Windows ME, and its predecessor, Windows 98 SE ("Second Edition" from 1999), is the recommended version for those wishing to play retro PC games un-virtualized. BTW, even though consumer-oriented Windows has not been DOS-based for almost two decades, some programs from old DOS-based Windows still run on recent PCs, because they relied on Windows APIs that are still supported, rather than needing to "drop into DOS" in any way; an important exception is that 16-bit Windows programs will not run on 64-bit Windows, only on 32-bit Windows; I wouldn't recommend using a 32-bit build of modern Windows for un-virtualized retro and modern PC gaming, though, because Windows 98 SE is more compatible with the retro games, and increasingly, modern PC games are 64-bit and therefore require 64-bit Windows.

[@CodexShow]

Thanks for the clarification James! A few people have brought this up, and it really just comes down to a miscommunication on my part. For the sake of time I glossed over the DOS stuff, but I'll keep all of this in mind for future videos.

[@quiltface83]

found it... now i don't have to say it.

[@henke37]

Based on and based on... It was far more complicated. Dos ran in a virtual machine even back in 3.1. Windows tried to avoid calling into dos code. If it could, it ditched the entire disk driver and used its own. If it couldn't, in case some funky dos driver was being used, it did, but it really didn't like to.

[@JamesLewis2]

The way I understood it was that DOS loaded first and then a special program called win.exe was launched to start Windows, even when it came to the limited "MS-DOS 8.00" that undergirded Windows ME.

[@DanSlotea]

@@JamesLewis2 Windows was an executable UI, not an OS. The OS was MsDOS. Another very useful UI was Norton Commander which saved a lot of command lines, the grandfather of Total Commander which nowadays saves a lot of clicks.

This video helped me remember the TV show “Cheat!” On G4 😂. Awesome video! I’m excited for more content. Funny thing is my first video game was Wolfenstein 3D but I didn’t play Doom till I was in high school or college. Definitely one of the best games ever.

[@monasteryfounder]

Cheat! was a special thing for us kids who were fascinated with the concept of cheat codes, secrets and Eggs, the culture of it all.

[@AXDOOMER]

If you had used the original Doom (in DOS) while no clipping, you would have seen the Hall Of Mirrors effect which is different under modern source ports. Modern source ports use double-buffering and Doom under DOS used page flipping. It's much more interesting to see in DOS.

[@CodexShow]

Thanks for bringing this up! I was going to mention the "shimmering" effect, but I'm saving the details of no-clipping for a future episode ;) PS your videos are rad, I don't know how you set up that 3-screen network setup, but gods bless you.

[@darsure3006]

haha i love the editing to match the music, people don't do that enough with skill like you did, good work =)

[@sc2thrashmetal]

wow, amazing video! just when i thought i knew just about everything about DOOM haha.

[@CodexShow]

Thanks dude! I was surprised to find out just how deep the rabbit hole went - I may do a second video on DOOM just to cover some extra stuff!

[@badnewsbruner]

After watching this video I was blown away that you only hve 3k subs, that is preposterous! This is high quality content, and you just earned yourself a new subscriber, great work my friend!! Keep it up, and thank you for your time and hard work! I can't wait to binge watch all of your videos :)

[@BrightArtWorkshops]

Fascinating video. 👍 A few years ago I met a guy and we went to a bookstore together where a book had the word “berserk” in the title. I told him that reminded me of Doom and he was really shocked and interested in the fact that I played Doom as a kid, and we talked about the game a lot that day. We got married this past spring and had IDKFA engraved inside his wedding band. I had asked him after he proposed if there was a moment he realized he wanted to get married, and he said it was in the book store talking about Doom. Lol 💕

[@CodexShow]

That's so nice, thank you for sharing Angie! It's really cool that such a specific thing brought you together. :)

[@darylallen2485]

Yeah, cool story!

[@lifes2good2]

Was expecting some basic rundown of codes. This was a very well produced documentary. Good stuff thanks. I played floppy disk doom as a kid and had no idea about the mods and death match scene. Cool!

[@Estupitastico]

If you haven't [played it], here's what you've been missing: *PIXELATION INTENSIFIES*

[@Kippykip]

Wow this is very high quality for someone with only 1K subscribers, nice work!

[@CodexShow]

Thank you! The response has been overwhelming, and I really appreciate it. :)

[@Argeaux2]

The no clip cheat code was changed to idclip for all other DOOM games after the original. Easier to remember.

[@blackflycanada4943]

Funny thing about that, I remembered that it changed in later Doom versions, but couldn't remember what it was. lol I played the crap outa shareware Doom forever as a kid. Always remembered IDSPISPOPD, was actually talkin to my buddy about it a couple days ago. Doom is legendary.

[@Ritley]

Wow I definetly didnt expect that kind of quality. Great video! Really enjoyed it and also learned something. Hope you'll grow bigger because you have a lot of potencial!

[@CodexShow]

Thank you for the nice comment! It's nice to discover other people are just as interested in this stuff as I am.

[@AmyraCarter]

BFG-9000. 'Nuff said. Well, that's until Unreal Tournament came along with the Redeemer... 😊 Can't go wrong either way. 💖

[@steviefranchize21]

Love the production value on the whole video from the narrating, the info and music! Keep it up

[@BOLL7708]

Subscriber #17 reporting! Honestly, with a video this good I thought you'd have subs in the gazillions! Well, it'll happen sooner or later 😗

[@CodexShow]

Thank you for the support, #17! Just happy to share my interests with internet strangers.

[@dirrt5011]

For anyone wondering what the song in the video is, it’s called Ottomatic by Oliver.

[@Kapin05]

You can play DOOM on your phone. I tried it, it's dope.

[@IsKor06]

I learned something watching this, and on a game I was thinking to know VERY well. Thank you, and kudos for making this enjoying to watch. I think you've got yourself a new sub!

[@jameswarner5878]

I alwyas remember IDSPISPOPD by saying "ID Smashing Pumpkins Into Small Pieces Of Putrid Debris"

[@producerevan88]

I'm friggin excited to see what you do after this man! awesome video!

[@Aerotactics]

IDFA probably means ID Full Arsenal

[@elijah7937]

God this game was my childhood .. My dad picked this game up in 1996 for 3 dollars and the cd is still kicking.. Its a must install even today.

[@krystoffersprague6100]

That's friggin aqesome, just goes to show ya they don't make em like they used to and old school still kicking it thanks to you taking care of that precious gem 😎👍

[@elijah7937]

Always will man. This game has a special place in my heart.

[@marscaleb]

Awww, you didn't mention how they changed the no-clip code in Doom II! Also, it would have been super awesome if you talked about the "cheat" codes in Heretic, if you try to use Doom's cheat codes in that game. It was relevant; it demonstrates part of the legacy that game had. And personally, I always thought of IDKFA as being "ID software Kicks Fat A**." Although it was more as a mnemonic device to remember the code, rather than a hidden meaning.

[@CodexShow]

I should have thrown that in for sure, that's my bad! As for Heretic, a video may be on its way sooner than you think ;)

[@marscaleb]

And here I was expecting the next video to be about the Konami code.

[@CarbonRollerCaco]

@@marscaleb Konami'd actually beaten Heretic to the cheat code troll party via SNES Gradius III; to enter the Konami Code right in THAT game, you have to replace the left and right pad directions with the L and R buttons or you Mega Crush yourself. Oh, the days when Konami was a good company…

[@GuiBiagioni]

Oh my F god, what a intro, what a simple yet complete way to explain. Good job.

[@Juanpopspacks]

Sick video bro. First video???

[@CodexShow]

Thanks bruh! Heckin' first video for sure, but it took me a while to polish. New episode coming soon!

[@josephbryant8790]

What an excellent video! From a production, editing, and research perspective. I wish you every success!!

[@dantoween6474]

I absolutely love your what you've missed edit at the start. really good editing with good flow :)

[@crispypeepohole69]

Nameless... erm, cough cough, Doom Guy cough cough. Also, I always interpreted (ID)FA as Full Armoury cos it makes as much sense as the others.

[@danielbain2921]

this video, is fantastic for such a small channel, this is really made extremely well. I can't imagine the amount of hours that went into this.

[@macos-brasil1814]

Too much of "there is a code, but, i will explain that after..."

[@noahg2]

Doom community and it's developers are simply the best

[@DoomMomDot]

I play doom on flash, and the cheat codes work. sometimes, I equip god mode, strap on my chainsaw, and just enjoy the carnage ...

[@CodexShow]

Keeping it casually badass, I like it!

[@krystoffersprague6100]

Awww yeaa!!!😎😈🔥 lol nice can't get that kinda satisfaction in today's FPS games sadly. I've got it on a psx emulator on my phone and occasionally test my longevity on nightmare to keep you on your toes, which gets you ready for now a days FPS games and you're almost untouchable 👍😎

[@ratykat]

How have I not found your channel sooner? This is amazing! Subbed!

[@CodexShow]

Thank you for the subscribe and the comment!

[@powdermnky007]

I see doom, I click like.

[@CodexShow]

This guy gets it.

[@powdermnky007]

I'm a simple man. ( ͡° ͜ʖ ͡°)

[@bub4886]

Wow, this is your first video? Incredible work! Loved DOOM so much as a kid so I just had to click on this video. Just subscribed and I hope to see more content!

[@buna-gf8ku]

0:55 nameless? his name is Doomguy

[@CodexShow]

Hahah fair enough, you got me there ;)

[@IngwiePhoenix_nb]

Awesome episode, well researched and...fancy effects! Your graphics-based elaboration underlined with embedded screencaps and the like really help the explanation by a lot for those that need an image to a word. Very well done! Subbed.

[@Certifiable]

"doom.exe" um, we only typed doom in the 90s.

[@xplinux22]

Just discovered your channel. This was a really cool and informative video! Thanks for making it. I'm watching the full interview too. Eagerly awaiting the next one!

[@watchmakerful]

Had anyone here ever played Heretic? Try to type IDDQD or IDKFA in Heretic...

[@CodexShow]

Ssh, you're spoiling the surprise! ;)

[@MarkVegaX]

Dang, this is one snappy video article. I love the flow of it all, how it marries what you see and hear with what you learn. Subscribed~

Thank you codex for the free games i downloaded on the pirate bay

Wow... found this by accident and now I'm subscribing! Good work dude... love the organization and flow of the script.

Request: Tomb Raider "nude" cheat

[@CodexShow]

Definitely something to consider, as it did have a big impact on the industry - at least from my perspective as a kid back then. Thanks for the suggestion!

[@darylallen2485]

Lol, not too much to think about here imo. Twenty-something boys and teen boys playing and making a game with a realistic female 3d avatar. A more riveting story would be how a young heterosexual male with testosterone coursing could refrain from imagining a naked Lara Croft!

[@ヴィンセントダモン]

This is an awesome video. You've done a great job with this. I assumed this was a well-established channel with tons of videos in the backlog because it is so well made and informative. I clicked over to the channel to find that it's the first one and it was just released! Wow! I'm subscribed for sure. Good luck with future videos! I'm left nostalgic and wanting a questionable IDDQD tattoo right now.

[@pyronophy]

Great video Kyle! This looks like it will become a great channel. Keep up the good work, fantastic production!

[@CodexShow]

Thank you for the kind words! I've got ideas for many future videos, so I look forward to sharing more interesting stories about beloved franchises!

[@zombievideomaniac]

Down the line I can say I was here since the very first video. great video man :)

[@creativecipher]

I thought this was some well known channel, because of the quality! But it turns out it will be in the future, good job.

[@Feuerartillerie]

Hey man, I loved your informative video, from the editing to the audio quality and the research. Subscribed and looking forward to more videos! Don't burn out though.

[@wallsag]

This took me back... Great job, please don't give up.
