Decompiler: Nds

The community has developed open-source plugins (such as ghidra-nds-loader ) that automatically recognize .nds files, map the correct memory regions for the ARM7 and ARM9 processors, and parse game overlays cleanly. Cost: 100% Free. 2. IDA Pro & IDA Free

As of April 2026, several high-profile "matching" decompilation projects (where the goal is bit-for-bit accuracy) are active:

If you want to “decompile” an NDS game: nds decompiler

Since the NDS uses the architecture, you need a tool capable of translating this specific instruction set. 1. Ghidra (Free & Open Source)

: A utility that helps organize decompilation projects by generating symbol files and identifying ARM9 sections. The NDS Reverse Engineering Workflow

Because the Nintendo DS uses standard ARM architecture processors (ARM946E-S and ARM7TDMI), you do not necessarily need a specialized "DS-only" decompiler. Instead, the community relies on industry-standard binary analysis frameworks equipped with ARM architecture plugins, alongside dedicated asset extractors. 1.

The game code is compiled into machine code for these two distinct instruction set architectures. When a developer compiled a game using tools like the official Nintendo SDK (often based on Green Hills or ARM compilers), the human-readable source code was transformed into raw ARM and Thumb instructions, stripped of variable names, comments, and high-level structure. The NDS decompiler’s job is to reverse this process, recovering as much abstraction as possible from this binary wasteland.
