Help:i need someone to compile Undertale NDS fan project / .nds ROM for me plz

Nolanakm5073 · Jan 14, 2026

Hi, I’m trying to run Undertale on my DS and I want a precompiled .nds ROM or guidance to compile it myself. I saw the UndertaleNDS GitHub project, but I’m not sure how to compile it with devkitPro. Could someone guide me or point me to a precompiled version?

It's required the files from Steam version of the game.

You obviously need the game data from the Steam version to actually compile it. Of course, we're not going to tell you where to get it from.

I don´t think it is needed to compile.

Download the three .patch files, the patcher.exe and the source code zip.
https://github.com/C3RV1/UndertaleNDS/releases/tag/v0.1

Extract the source zip anywhere and copy the other files and a data.win into this directory.

Finally double click patcher.exe and select data.win and the three .patch files.

Now there´s a Undertale.nds file created --> the game.
(Which doesn´t run on some flash cards or emulators)
