The Nintendo DS (NDS) remains one of the most beloved handheld consoles in gaming history. For developers, researchers, and hobbyists, peering into the inner workings of an NDS ROM – often for translation, modding, or educational purposes – is a challenging but rewarding endeavor. This article provides a comprehensive overview of NDS decompilation, detailing the essential tools, methodologies, and platforms used to analyze and potentially reconstruct the source code of Nintendo DS games.

Its Medium-Level Intermediate Language (MLIL) provides a incredibly readable abstraction of assembly code, bridging the gap between a pure disassembly and a full C decompilation. 4. Specialized NDS Rom Tools for free NDS reverse engineering
If you want to convert a raw binary into assembly code, you will need a disassembler. Several tools are dedicated to this task, each with a different focus.
The target binary (usually arm9.bin ) is loaded into the decompiler (e.g., Ghidra). Because the NDS has specific memory regions (like VRAM, Main RAM, and IO registers), the developer must use an NDS loader script to map the binary segments to their correct architectural memory addresses. Without this, pointer references will fail to resolve. Step 3: Signature Matching
