User Files for Undertale

Requirements

- Ubuntu 20.04
- libTAS 1.4.2
- Undertale v1.0


Port Windows Undertale v1.0 to Linux

1. Download Windows Undertale v1.0 on a Windows machine in Steam by right-clicking on Undertale in your games library -> Properties -> Betas, then selecting old_version_100 in the list.
2. Once downloaded, the game can be found in C:\Program Files (x86)\Steam\steamapps\common\UNDERTALE. It comes as a packed .exe file, so unpack it using 7zip, WinRAR, or similar programs. You should get the .ogg music files, UNDERTALE.exe, data.win, and a few other files.
3. From the extracted files, rename data.win to game.unx
4. Create a folder to put the game files into. You can call it whatever you want, for example "Undertale v1.0 Linux". Inside this folder, create a folder named "assets" (without the quotes) and move all the extracted files into this folder.
5. Unzip https://files.tasvideos.org/emulatordownloads/linux/runner-linux-GameMakerStudio-1.4.1567.7z and copy it into the "Undertale v1.0 Linux" folder. This file is the "runner" file, essentially the Linux version of the UNDERTALE.exe file found on the Windows version. It executes the code found in the data.win (or game.unx) file.
6. You should now have the following folder structure: the "Undertale v1.0 Linux" folder, which contains the runner file and the assets folder, which contains all the extracted files (most importantly game.unx and the .ogg files).
7. Copy the "Undertale v1.0 Linux" folder to your Linux machine and start the game by executing the "runner" file via the command "/path/to/runner" (no quotes, and use the actual path). You may need to make it executable first via the command "sudo chmod +x /path/to/runner" (no quotes, and use the actual path).
8. You may also need to install extra dependencies by entering this command into a terminal:

 sudo apt-get install libopenal1:i386 libssl1.0.0:i386 libglu1-mesa:i386 libxrandr2:i386 libfreetype6:i386 libfontconfig1:i386


Force Debug mode to ON

1. You will need a hex value editor, like HxD.
2. Find game.unx in your Undertale folder. Hashes should be
- MD5:   D0822E279464DB858682CA99EC4CBBFF
- SHA-1: 0A6586B621A1E7535E8391326145B89D01E9DDA1
3. Open it up with your hex editor, and go to address 725B24
4. Change the value from 00 to 01.
5. Save the file. Hashes should become
- MD5:   92B63516FA8410F72AD42459F0EA5E59
- SHA-1: FD0EC68FB47875805A8D7C5C546E236AEB74772E


Setup the save files for verification

1. Go to ~/.config/UNDERTALE and ensure it's empty.
2. In libTAS, uncheck Runtime -> Prevent writing to disk.
3. Replay this movie and stop the game after it ends.
4. Open ~/.config/UNDERTALE/file0 in a text editor
5. On line 1 (character name) change H to this text (it contains various control characters to change font and color):
\TF \RB\F0U\F1T \E1HE\E2Y!\E3!\Ts \WT\E4od\E6ay\E7's\E8 T\E9AS\E5 i\F0s \F2sp\E3on\E2se\E1re\E0d \F0by\TF \RR\F3AI\E2D:\E3 \OS\E4H\YA\F0D\OO\F4W \YL\E1E\OG\E2E\YN\E3D\OS\E5,\Ts \Wo\E6ne\E7 o\E8f \E9th\F0e \F5bi\E7gg\E6es\E5t \E4mo\E3bi\E2le\E1 R\E0PG\F0s \F6of\E2 2\E302\E42!^1 \R1\E90 \Om\E6i\Yl\E7l\Gi\E8o\Bn\E5 u\Ps\F0e\Rr\F7s \Wh\E3av\E2e \E1jo\E0in\F0ed\F8 R\E2ai\E3d \E4ov\E5er\E6 t\E7he\E8 l\E9as\F0t \F96 \E7mo\E6nt\E5hs\E4, \E3an\E2d \E1it\E0 h\F0as\F3 a\E3n \E2al\E0mo\E2st\TF \RP\E3E\OR\E2F\YE\E0C\GT\E2 S\BC\E3O\PR\E2E\Ts \Wo\E0n \E2th\E3e \E2Pl\E0ay\E2 S\E3to\E2re\E0!!\E2!^2 %%
6. On line 13 (first inventory slot) change 0 to 26 (Punch Card item ID).
7. Save the file.
8. Open ~/.config/UNDERTALE/...

The TAS was made on version 1.0 of Undertale, which doesn't have a Linux release, meaning it can't be TASed in libTAS by default. Fortunately, Undertale is a GameMaker game, which can relatively easily be ported to Linux with the following steps:
*Download Windows Undertale v1.0 on a Windows machine in Steam by right-clicking on Undertale in your games library -> Properties -> Betas, then selecting old_version_100 in the list.
*Once downloaded, the game can be found in C:\Program Files (x86)\Steam\steamapps\common\UNDERTALE. It comes as a packed .exe file, so unpack it using 7zip, WinRAR, or similar programs. You should get the .ogg music files, UNDERTALE.exe, data.win, and a few other files.
*From the extracted files, rename data.win to game.unx
*Create a folder to put the game files into. You can call it whatever you want, for example "Undertale v1.0 Linux". Inside this folder, create a folder named "assets" (without the quotes) and move all the extracted files into this folder.
*Copy [https://cdn.discordapp.com/attachments/273954449721131028/837024631776739409/runner|this file] ([https://files.tasvideos.org/emulatordownloads/linux/runner-linux-GameMakerStudio-1.4.1567.7z|TASVideos mirror]) into the "Undertale v1.0 Linux" folder. This file is the "runner" file, essentially the Linux version of the UNDERTALE.exe file found on the Windows version. It executes the code found in the data.win (or game.unx) file.
*You should now have the following folder structure: the "Undertale v1.0 Linux" folder, which contains the runner file and the assets folder, which contains all the extracted files (most importantly game.unx and the .ogg files). Copy the "Undertale v1.0 Linux" folder to your Linux machine and start the game by executing the "runner" file via the command "/path/to/runner" (no quotes, and use the actual path). You may need to make it executable first via the command "sudo chmod +x /path/to/runner" (no quotes, and use the actual path).

You may also need to install extra dependencies by entering this command into a terminal:

 sudo apt-get install libopenal1:i386 libssl1.0.0:i386 libglu1-mesa:i386

A zip archive containing all the files needed to sync the tas can be found [https://drive.google.com/file/d/1MJoXNoMpKjtipomc3WQtiytXjDAx20lY/view?usp=sharing|here].

To mod the game to sync with the TAS, do the following:
*Replace assets/credits.txt with the modified version from the archive.
*Apply the noclip.bps patch from the archive to the assets/game.unx file using Floating IPS (Flips). A version of Flips is also included from the archive, or the original can be downloaded fom [https://www.smwcentral.net/?a=details&id=11474&p=section|here]. This patch modifies the game to allow pressing F10 to toggle noclip. This functionality is only used for a single frame of the TAS.

To start with the correct save file, copy all the files from the "start_save_files" folder from the archive into {{/home/<Your Username>/.config/UNDERTALE}}. If you've run this movie past the first few hundred frames, you'll have to copy the files into {{/home/<Your Username>/.config/UNDERTALE}} again, every time.

For the TAS to sync, you must check ''Runtime > Time tracking > clock_gettime()'' and disable ''Runtime > Prevent writing to disk''. You must also avoid fast-forwarding through frame 72389 of the TAS. I think this is some sort of libTAS bug where fast-forwarding may incorrectly emulate audio volume, since in that area of the TAS there is a cutscene that ...

Game summary: Undertale

Undertale is a game about subverting the player's expectations. The game never explictly lies to the player, but it frequently gives the player incomplete information and allows the player to lie to themself.

[WARNING: The remainder of this summary includes very important story spoilers. I've rot13'd it to avoid anyone reading it by accident.]

Game summary: Deltarune

Although the name of "Deltarune" could be considered a spoiler, I'm going to assume it's known widely enough that I shouldn't bother trying to be mysterious about this.

Deltarune is the mysterious sequel to Undertale. It takes place in a universe different, but not quite separate from the one in which Undertale takes place. It was released on October 31st 2018 via a series of mysterious tweets from the Undertale Twitter account.

The original website on that day can be seen in the Internet Archive: <https://web.archive.org/web/20181031130251/https://www.deltarune.com/>

Once again, the game never explicitly lies to the player, but it does take every opportunity it can to make the player lie to themself. The player thinks they're taking a survey (which is technically true), but the result is discarded and the true game begins once the survey is completed.

Gameplay follows a similar format to Undertale, but combat is done in a party of one or two additional characters, and running exists as a movement mechanic. Also, instead of random battles, the game shows all encounters in the overworld as characters that chase the player.

Footnotes:

¹ no-hit refers to no damage dealt or taken. These rules are violated in cases where gameplay makes it impossible to do otherwise.
