as a modder for this game, i can confirm its made from hopes and duct tape

[@Undertalenjoyer]

basically walls of if statements

[@abdillahahmad7025]

hopes and dreams and a large switch statement

[@fujiwaranonekobiodrando1257]

Homes and ducks

[@Fox-p3w]

Hopes, dreams and duct tape

[@tomas_iss7469]

Reminded me of the running joke along Gamerchamp3000’s minimalist pacifist metroid 1 run video. Basically saying the game was made on various kinds of increasingly weird, ridiculous and funny kinds of duct tapes

[@ninjaneb1]

Honestly, finding a slice of butterscotch cinnamon pie circled in Toriel's diary feels like something that would actually be in the game

[@Isakube]

BRO I JUST REALIZED I COULD DRAW A RED CIRCLE AROUND MY BUTTERSCOTCH CINNAMON PIE

[@intangiblematter_misc]

Toby Fox made a game that rival the games of his childhood, both in quality and the absolutely bizarre bugs that are created because of quirky ways of doing things under the hood

[@sansyusuf]

Toby fox: yeah i conected musics and names and all the stuff so i tought it would be cool to conect all the code together!

[@Undertalenjoyer]

FR

[@quiet_nightz]

considering the fact a dog canonically just barked into a computer translating it to code, no wonder theres overflow in texts

[@Donobodude]

It’s a little funny, you can kinda see what order things came in development i.e. toby thought about pink names while working on Muffet

[@Lolek14-vk8rf]

Ngl that would be fire

[@sophiez96]

you can get pink names by talking to a specific froggit to tell you about the yellow names I don’t remember to what the specific dialogues are but pink names are obtainable by telling the froggit that yellow names are lame so they switch to pink names

[@SUPERNTORB]

​@sophiez96And then you can find some yellow names in a garbage pile near a save point in waterfall

[@U23rN4Me]

Tbh the pink is a little too pale imo

[@LazerGUN-ep8rm]

[@Cr_nch]

0:19 I program as a hobby and when I reached this I started sobbing uncontrollably

[@Liploof]

the monsters may have hopes and dreams, but the code is powered by it.

[@cq.cumber_offishial]

this is what happens after you put all your dialogue in a single if statement

[@ShaneBarton2005]

And yet, Undertale is somehow more stable than Yandere Simulator.

[@opagel]

*switch

[@cq.cumber_offishial]

@ what about bottom

[@rorucopexperements]

​@ShaneBarton2005 that's because it is a case statement not 500 million nested if loops

[@maximized_1]

someone should animate characters in undertale reacting to frisk materializing a frying pan out of a bag of dog food or frisk walking past mad dummy by looking at a piece of paper

[@Undertalenjoyer]

True that would be canon tho

[@Lucas264]

7:54 Turns out after all these years, you actually can get the ancient artifact - instant noodles!

[@NutBreadMSMC]

I think there’s an overflow in True Lab where if you overflow the chisps dispenser you can get Toriel’s call asking you about butterscotch cinnamon pie (for some reason)

[@Undertalenjoyer]

Yeah it's true

[@sussdood]

i like how napstablook wants your soul

[@Cloudy-creator1]

It’s not a glitch, it was made so if someone was lazy they could farm pie.

[@ticolinoticole4337]

Reminds of the infinite lifes glitch using the Koopa in NES Super Mario Bros

[@GoofySlugpup]

toby should add and extra line between those that makes everything you have butterscotch pie. Armor: pie. Weapon: pie. Health: 3.14 Attack an enemy? 3.14 damage by throwing a pie at them. Would be really funny

[@WafflingArc]

I’ve been able to do this with a punch card on the original version it can be quite funny!

[@Undertalenjoyer]

I didn't check that with punch cards, interesting. But yeah it's pretty neat

[@spark_two]

Ah yes the punch card, truly an unintended game-breaking item.

[@baldi_real_no_fake]

​@@spark_twoi feel like its punching the game itself

Thanks for the free Rock Candy, Napstablook!

[@temmie5764]

i love how badly coded this game is

[@shinshi1972]

And for some reason it's more stable than YanDev coding

[@amogus_definitivo]

Yeah man your games have so much better code like bro u put much more effort in ur games Even more than Toby Fox man they are so good like ur dad (because u don't have one)

Great video, didnt think i'd watch the whole thing but here we are:)

[@yurab1834]

Not gonna lie, I have no idea why Undertale would use a monster switch statement for *all* its dialogue and at this point I'm too scared to ask I should just go find a way to read the source code and look at it myself

[@MemeLad147]

9:04 I’m pretty sure this dialogue is related to an unused horse stable object in the game, not sure why it’s there though.

[@Undertalenjoyer]

Exactly. [redacted] is a weird character hidden in the room_redacted, however at the snail farm room in waterfall (which is connected to the snail race room btw) a poorly drawn horse stable existed, and [redacted] appeared inside. I think it was possibly for testing the fade effect when you get close to napstablook, and the closer you get, the more he appears, ([redacted] also shares the same fade effect) which could be true considering it's the same room where napstablook exists. Just my rough speculation.

[@DaVince21]

Okay, I can't say I expected the entirety of the text logic to be an absolutely massive switch-case statement. That, uh, sure is some coding. 😅

[@ShadowEclipse777]

Still an order of magnitude or two better than Yandre Dev's abomination of an if-else statement

[@lev7509]

He's using case numbers like line numbers in BASIC... it's a miracle how such code is behind a masterpiece.

[@SpringySpring04]

The first 10 seconds feels oddly in-character for Undertale's sense of humor

[@colonelclev4500]

7:50 is the moment we learned that the legendary artifact, is in fact: a refrigerator.

[@mrowlsss]

So, theoretically, could you freeze the game and press Z so many times that it overflows to a switch case hundreds away from the start?

[@Undertalenjoyer]

Well not exactly, cause of the gaps that are between cases. It picks the next case in order, and if the next case is nonexistent, it will default to the 1st one, which just has a break statement. However it will start to overflow from the 1st case and then it will go to the next cases like 1, 2, 3 etc. Till it finds a gap to start the whole loop again or results in a crash before you could even get to a gap

[@vencedor1774]

Why the hell undertale has as many bugs as an old nintendo game?

[@sussdood]

Because why not

[@KingNoahCraft5]

cause toby used to be a rom hacker for old nintendo games

[@callmedeltah]

It's basically coded like an old Nintendo game. Which makes sense considering Toby's background.

[@kids9699]

The reason the part at the start happens is bc you find a butterscotch-cinnamon pie before reading the passage

[@DudegamerW]

yayyy finally, a new glitch found after undertale's 9th anniversary that is very, very interesting i love this kind of stuff wait, what do you mean this has been used in speedruns whaaaaa

[@Undertalenjoyer]

Honestly the fact that people still find this kind of things interesting after 9 years of the game's release is amazing. and yeah it is used in speedrunning to get an early burnt pan.

[@SapphicAllie]

for anyone curious, overflows are possible in early versions using the punch card, and are a common speedrun strategy. so no, you don't need debug mode

[@Undertalenjoyer]

this was carried out on version 1.08 so it's possible some stuff was fixed. Is there an instance where players use this glitch beyond getting an early burnt pan though?

[@Blackfromstickworld]

This will definitely become a apeedrunning tactic

[@eldis_the_lifeform]

@Undertalenjoyer ikr?

[@emre_ez]

A dog barking with Speech to Text would have made a game thats better coded tbh

[@jodohe]

In Deltarune on the Switch there is a bug which appears when you buy 400 Bagles and you go to the Switch Menu after the screen became black and you go back in the game and you interact with K_K again than you get nearly all the dialogs in the game which have choices. (If you done everything right you need to answer every choice twice and I think the text is smaller than useally) Is this glitch the same like here or is this something else? Also, Through this glitch you can get the Thorn Ring and the Egg in any route.

[@Undertalenjoyer]

I believe this glitch is also used for early castle travel, which is also a speedrunning strat. I have no idea if its the same, because I didnt investigate deltarune's code yet.

[@ItsAubreeyy]

9:03 i think this is from an unused room

[@Arsenniy]

man thats cool

[@emre_ez]

Undertale Powered by GameMaker, Hopes and Dreams

[@Rodrigo-kq3js]

"but if a choice is made twice it will go to the next case twice" What the fuck is wrong with this game. what. why would you do this.

[@Lord_Arcane]

And how do I turn on debug mode?

[@Undertalenjoyer]

Depends on version and OS but here you have it: A debug mode can be activated by using a hex editor: change 00725B24 (in version 1.0), 00725D8C (in version 1.001), 00725DDC (in version 1.001 Linux), 007748C4 (in 1.08) to 01 in data.win (Windows versions), game.unx (Linux), or game.ios (Mac OS X).

@@Undertalenjoyer I see. I am on Windows and I don't know witch version I am, its problably the latest one, but thanks, I will try it later

@@Lord_Arcane after you open the game in main menu you should see before continuing the version of Undertale you have. You're welcome 👍

[@UpClear13]

@Undertalenjoyer what version would my switch Undertale copy be if downloaded? (Edit: I meant to ask how to to debug on Switch, whoops!)

[@Lord_Arcane]

@UpClear13 I don't know if its possible to do this on switch, since you would have to enter the game files, but I might be wrong since I don't have a Switch

@therandomuseronyoutube hi

[@JasonCharlton-n9p]

Toriels played these games before..

[@bluemycool]

Why do you need debug mode for this though?

[@Undertalenjoyer]

while interacting with something, a text box appears and you can't move, so you need to hit F10 to be able to move again, which also allows you to interact with something again.

[@crusher9z9]

just punch card glitch

Thanks for making utdr content! Just wanted to share this info in case it's helpful for you - feel free to disregard if not! Adding audio of your script read aloud (even if by AI) can make your video accessible to background-listeners, visually impaired listeners, ESL viewers, and viewers who struggle with reading speed whether from proficiency level or physical impairment (like my learning disability). This is not criticism! Your video is great and you should make content in the way that feels good to you. This is just additional info if you're looking to grow your audience to these sections of the userbase. Thanks again for making utdr content! Have fun. ❤

[@Undertalenjoyer]

I considered that but I'll stick to that form. I maybe losing some viewers but undertale fans are usually people who are capable at reading comics, theories, AUs (based on text), toby's tweets, dialogues, lore, maybe even wattpad fanfics. They are as a matter of fact fans of reading. (And also I think AI is kind of unnatural. As for making a real voiceover, I'm not really confident with that. Please understand.)
