Decompiler — Nds

: You can use specific loaders to import .nds files directly, allowing Ghidra to map out the ARM9 and ARM7 processors' memory spaces automatically. 2. ds-decomp (Automated Toolkit)

: The industry standard for professional reverse engineering. It features the highly accurate Hex-Rays Decompiler but requires a paid license for the full version.

There is no single "double-click" software that automatically spits out a perfect Nintendo DS game source code. Instead, reverse engineers rely on powerful, generalized interactive decompilers equipped with ARM-architecture support. nds decompiler

Demystifying the NDS Decompiler: A Guide to Nintendo DS Reverse Engineering

The long-standing industry standard for static binary analysis is IDA Pro. It features class-leading decompilation capabilities for ARM architectures but remains locked behind a restrictive commercial paywall, pushing most independent retro-gaming communities toward Ghidra. Decompiler vs. Asset Extractor : You can use specific loaders to import

Before you can decompile the code, you have to find it. Tools like allow you to open a .nds ROM file and browse its internal file system (the ROM File System). You can use them to extract the arm9.bin and arm7.bin files, which are the actual executables you feed into Ghidra or IDA. Step-by-Step: How to Decompile an NDS ROM

If you want to “decompile” an NDS game: It features the highly accurate Hex-Rays Decompiler but

The only way to get perfect source code is —a human reading the decompiler's output and rewriting it into clean C. This is exactly what the Decompilation Projects for Super Mario 64 or Ocarina of Time did. For NDS, similar efforts exist for New Super Mario Bros. and Pokémon Diamond/Pearl , but they are community-driven and take years.

Static code is hard to read because addresses are absolute. Dynamic analysis helps you understand when code runs.

The Hex-Rays decompiler generates exceptionally clean, structured C-like pseudocode.
