If you are looking to reverse engineer a specific title, the standard workflow follows these steps: AetiasHax/ds-decomp: Toolkit for decompiling DS games 3 Apr 2026 —
for recovering original source code. The best you can get is disassembly (ARM/Thumb) with some help from decompiler-like features in tools like Ghidra or IDA Pro .
: A utility that helps organize decompilation projects by generating symbol files and identifying ARM9 sections. The NDS Reverse Engineering Workflow
An attempts to reverse this process. It takes the compiled binary from an NDS ROM and analyzes the machine instructions to reconstruct the original C/C++ logic, variable structures, and control flows. Decompiler vs. Disassembler It is vital to distinguish between these two tools: nds decompiler
Decompiling a Nintendo DS (NDS) game is a multi-step process that has become significantly more accessible with modern tools. Unlike simple "one-click" decompilers for high-level languages, NDS decompilation involves unpacking the ROM, decrypting its contents, and then using a reverse engineering suite to turn binary code back into readable C or assembly. 1. Essential Tools for Your Toolkit
are used to unpack the ROM, separating the header, the ARM9/ARM7 binaries, and the file system (SDAT for sound, NARC for archives). Disassembly:
Created by the NSA and released as open-source software, has become the go-to platform for Nintendo DS reverse engineering. If you are looking to reverse engineer a
Modern and legacy compilers rearrange instructions, inline functions, and optimize loops to save space and performance. This makes the resulting decompiled C code look vastly different from what the original developers wrote.
Decompiling a Nintendo DS game is the process of converting the machine code (binary) stored on the cartridge back into a human-readable format (such as C or C++ source code). This is a reverse engineering process used for game preservation, creating fan translations, or fixing bugs in old games.
An open-source, cross-platform utility specifically for packing and unpacking NDS ROMs. The NDS Reverse Engineering Workflow An attempts to
Some games (mostly first-party Nintendo titles or debug builds) contain .
If you want to decompile an NDS ROM yourself using modern tools like Ghidra, the typical workflow follows these steps: Step 1: ROM Unpacking
