This download includes a modified runner file (UNDERTALE.exe) that fixes performance and graphical issues exclusive to 1.001 Linux on Windows, to make the game run more accurately to the Linux version. Also included are instructions for obtaining 1.001 Linux from Steam for running it on Windows. This runner file is legal for use in any runs on the Undertale leaderboard when used with 1.001 Linux on Windows.

1.001 Linux on Windows runner and installation instructions

51 saves before most skips where the punch card saves time, or otherwise before major points in the game. TPE route, but includes a lvl 4 save before Asgore (neutral).

All Punch Card saves

All saves needed for your Undertale speedrunning enjoyment!

This patch can be applied to the data.win of version 1.08 to downpatch it to 1.05. This patch is approved for official runs, as the resulting game is an exact match to the official 1.05 release of Undertale.

Downpatch 1.08 to 1.05

These are the files necessary for the Early Punch Card category. Use these files if you wish to run the category.

Early Punch Card Save Files

The function of this script is to open/close flowtimer with a hotkey, this can be useful in strats like mad dummy skip.

Flowtimer Script

The two hardest parts of the Genocide path, other than getting a decent time in Snowdin, are the Undyne and Sans fights. It would likely drive a lot of people away if the only chance they had to practice the fights was when they got to said fights, and even then they'd probably be behind the leading splits because of item use.

I'm providing this for common courtesy, though the other save file was found on Reddit since I didn't feel like going through the worst parts of the game to get to Undyne and then just stop there.

I'm not sure where Undertale's files are saved on non-windows platforms, but on Windows it's C:\Users\USERNAME\AppData\Local\UNDERTALE.

The only thing you can't fully replace just by altering appdata files is finishing the Genocide run, so you still have to wait ten minutes between complete runs as a minimum.

Genocide Bosses

This is the half-speed automash mod. Patches are included for versions 1.00, 1.001 Linux, 1.05, and 1.08. Please see the readme for instructions on how to install and use this mod. This mod is allowed in all categories.

Half-speed automash mod

This is a speedrun practice mod for Undertale v1.001 Linux, intended for IL practice. It includes a built-in savestate system, customizable RTA timer, and pre-defined Hotland IL splits.

*Note: This mod is no longer being updated. For general use I suggest downloading the [Neutral/TPE Practice Mod](https://www.speedrun.com/undertale/resources/nw7qn), which is currently in active development. For now this is the only mod legal for leaderboard-submitted IL runs.*

IGT Savestate Mod

This file contains approved save files for the Individual Levels board. Includes saves for all 3 categories, with the correct items and for each, and correct LV and Kill Counts for Genocide.

IL Approved Save Files

These save files are approved for ILs on v1.00 only as this is the only version known to have a setup to obtain the punchcard in a genocide run. Runs done with these saves on any other version will be rejected.

IL Hotland/New Home Genocide save files with punchcard (v1.00 ONLY)

This save is for the True Lab Any% IL category where the Endogeny switch is activated before entering True Lab. Since this glitch is only known to be possible on 1.001 Linux and 1.001 Mac, these are the only versions these saves can be used with in submitted runs.

IL True Lab Any% Endogeny skip skip (1.001 Linux/Mac only)

For use with KeysPerSecond (https://github.com/RoanH/KeysPerSecond). This is the layout I use, it's a nice alternative to NohBoard. The ZIP includes 2 versions, one with and one without the KPS display.

New Game+ Glitchless Save

This is a save file for the New Game+ category, which has already defeated Photoshop Flowey. This allows for Monstertale and Flowey to be skipped. Reset on the main menu of the game to start the run.

For Nohboard Rewrite v1.3.0. This one includes both right shift (+ctrl) and left shift (+ctrl) that appear as the same button on the layout.
Place in "NohBoard-ReWrite-v1.3.0\keyboards\Games" as its own folder, and change the style since this is the one I personally use. Made using already existing layouts (most likely from starsmiley + xandertje10)

Nohboard v1.3.0 Layout for Undertale

Use this to practice the Genocide Lab Skip.

Non-PCE (Genocide) Lab Skip Save

Thought I'd share a script which allows you to remap your keybinds from arrow keys to WASD. You can modify the script to ur liking as long as it doesn't break the rules.

In order to use the script you must download "AutoHotKey" first which you can find by searching it up on google.

Start the script and you're done, as long as it runs in the background minimized u won't need to reopen it each time you launch the game.

Important thing to note is that the script doesn't work when you reload the game for the very first time for flowey, it starts working again once u enter the flowey fight. This is due to the undertale window not being titled "UNDERTALE"

Remap Keybinds

Sans bossfight with ballet shoes, burnt pan, pie and noodles

Sans bossfight

This is a savestate mod that can be installed on any PC version of Undertale. Included is a .csx file that can be installed using UndertaleModTool as well as a .bps patch for 1.001 Linux that can be installed with Floating IPS. If you're using a version other than 1.001 Linux, you must install the mod with the .csx file in UndertaleModTool. Once the mod is installed, you can select a save slot with 0-9, save with S, and load with L. The savestates are saved in your normal save folder as savestate_#.

Savestate mod (for all versions)

This is a speedrun practice mod for Undertale v1.001 Linux, intended for practicing glitched Neutral and True Pacifist speedruns. It includes a built-in customizable timer, savestate system, a quad practice tool, and an MDS practice mode.

*Note: This is currently not permitted for IL leaderboard submissions. If you're looking for a convenient in-game timer for IL submissions, use the [RTA Savestate Mod](https://www.speedrun.com/undertale/resources/649bi) instead.*

This tool takes your textbox mashing as an input and gives you detailed statistics on how you did to help you improve. The tool continues to receive input even after losing focus, so you can mash in the Undertale game window and it will still be picked up by the tool.

NOTE: Your antivirus might pick up on this file because of the way it works. I can provide the source code on request, and I'll try to get a github page at some point.

Undertale Mash Practice Tool

a .kb file to display only the undertale relevant keys on NohBoard. Just put it in the folder with all the other .kb files and you can select it under the "Games" section in NohBoard settings.

Useful if you want to display your inputs on a stream but don't want 80 unnecessary keys.

Undertale NohBoard Config

A Nohboard Layout that includes Alt and Space for those who use Alt-Space buffering. If you don't Alt-Space buffer, I would recommend using the previous version because it is much cleaner

These are the basic splits for all of the main categories, to be used on LiveSplit. You can customize them to your liking.

Undertale Splits

This is an updated version of the old nohboard layout. The old one didn't have ctrl, so i added it.

Put this .kb file in your nohboard folder. Start up nohboard, right click, and click settings. This will bring up a menu. Set the keyboard category to "Games", and set the keyboard the name of the file. This will select the nohboard layout.

Updated Nohboard Layout

This mod makes it easier to practice weapon attack patterns. Apply the patch to version 1.001 Linux using Floating IPS.

See the included README.txt for more details

Weapon Practice Mod

You can improve your weapon handling skills on Endogeny with this save. Endogeny is the best to do this on because he does not attack once met his spareable condition and he is invincible.
