Finding a way to play Undertale on the Nintendo DS is a popular quest for fans of both the game and retro handhelds. While Toby Fox officially released Undertale on various consoles, the original Nintendo DS and 3DS were famously excluded because GameMaker (the game’s engine) did not support them.

However, the homebrew community has stepped in with a dedicated project that allows you to run a version of the game on your DS. Here is everything you need to know about finding and setting up the best "Undertale DS ROM" experience. The Best Current Version: UndertaleNDS by Cervi

The most functional way to play is through the UndertaleNDS project on GitHub. This is a fan-made port specifically designed for the Nintendo DS hardware.

Status: It is currently considered a prototype or demo. While it successfully recreates the core mechanics and the beginning of the game, it is not a full 1:1 port of the entire Steam experience.

Unique Feature: To avoid piracy and respect the original creator, this homebrew requires you to provide your own legally purchased copy of Undertale from Steam to "compile" the ROM. How to "Download" and Install

Because the project uses your own game files to build the ROM, you won't find a legitimate pre-compiled .nds file on standard ROM sites. Instead, follow these steps to create your own:

Download the Patcher: Visit the C3RV1 GitHub repository and download the latest release files, including Undertale.nds.patch and the patcher tool.

Locate your data.win: In your Steam library, find your Undertale installation folder and locate the data.win file (usually under C:\Program Files (x86)\Steam\steamapps\common\Undertale\).

Run the Patch: Use the patcher tool to combine the data.win file with the DS patch. This will generate your personal Undertale.nds ROM file. Hardware/Emulator Setup:

On Hardware: Move the .nds file to your R4 card or flashcart's microSD card.

On Emulator: Use NooDS or MelonDS for the best performance and audio quality. Are there 3DS Options? If you are using a 3DS, you have a few additional choices:

Undertale-3DS Demake: A newer project on GitHub by CooingMaxito aims to bring a "demake" version to the 3DS, though it is currently in very early development.

LOVE Homebrew: Another project called LOVE provides an Undertale-inspired experience on the 3DS without using the original game's code.

C3RV1/UndertaleNDS: Undertale port for Nintendo ... - GitHub

To play on a Nintendo DS, you generally need to use a homebrew port, as there is no official release for that console. The most stable method involves using the UndertaleNDS project, which requires you to provide your own legal game files to create a playable ROM. 1. Requirements A PC (Windows or Linux) to run the patching tools.

Legal Copy of Undertale: You must own the game on Steam or GOG to get the data.win file.

UndertaleNDS Files: Download the latest release (including the patcher and .patch files) from the C3RV1/UndertaleNDS GitHub.

Hardware: A Nintendo DS/DSi/3DS with an R4 Flashcard or a console running TWiLight Menu++. 2. Creating the .nds ROM

Because of copyright, the homebrew creator cannot distribute the full game. You must "patch" your own files:

Locate data.win: On Steam, go to your library, right-click Undertale > Manage > Browse local files. Copy the data.win file to a new folder on your desktop.

Prepare Patcher: Place patcher.exe and Undertale.nds.patch in that same folder.

Run the Patcher: Open patcher.exe. When prompted, select your data.win file, then select the Undertale.nds.patch file.

Wait for Completion: The tool will generate a new file named Undertale.nds. 3. Installing on Your DS

For R4 Cards: Connect your microSD card to your PC. Copy the Undertale.nds file into your Games or ROMs folder. Safely eject, put it back in the R4, and launch it from the menu.

For 3DS (Homebrew): If you use TWiLight Menu++, place the ROM in /_nds/ or your standard ROMs folder on the SD card.

For Emulators: The creator recommends MelonDS for the best audio and performance on PC. Important Notes

Development Status: Most DS ports are currently demos or "work in progress" prototypes. They may only include the first few areas, such as the Ruins.

3DS Alternative: If you have a 3DS, there is a more complete "True Port" available on hShop or via Project Sunshine that offers better performance and full game features.

There is no official Undertale DS version released by Toby Fox. Any “Undertale DS ROM” circulating online would be a fan-made port or a hacked reproduction, not a legitimate Nintendo DS game.

Downloading ROMs of copyrighted games — even modified fan versions — generally violates copyright law, unless you own the original game and are creating a backup for personal use (which doesn’t apply to a non-existent official DS version). Additionally, sharing or downloading such files can expose you to malware or legal risks.

Undertale Red & Yellow Port: A recently updated fan project found on platforms like PortMaster, though this is often intended for Linux-based handhelds rather than native DS hardware. How to Install Fan Ports

Obtain Original Files: You typically need the data.win file from a legitimate Steam or GOG installation of Undertale.

Use a Patcher: Projects like UndertaleNDS on GitHub provide .patch files. You must run a patching tool (like patch_all.sh or a Windows-based .exe) to merge the fan code with your legal game assets to create the playable .nds file.

Hardware/Emulation: Once patched, you can run the ROM on a DS flashcart (like an R4 card) or via an emulator like MelonDS for the best audio and performance results. Important Safety Note
