The World of NDS Decompilation: Understanding the Tools and Techniques
1. Introduction
10. Conclusion
- Decompilation quality: Output pseudo-C is often incomplete, with incorrect or missing types, crude control-flow reconstruction, and many helper stubs — typical for decompilers on embedded ARM code.
- ARM7/ARM9 interactions: Correctly attributing shared resources or inter-processor comms can be brittle; some function calls across processors require manual verification.
- Library/function recognition: Custom or heavily optimized code reduces automatic recognition; standard library functions are identified more reliably than game-specific routines.
- Data vs. code ambiguity: False positives (interpreting data as code) can appear, especially in overlay or packed sections.
- User interface (varies): Some implementations focus on CLI; GUIs may be minimal compared with mature reverse-engineering suites.
- Legal and ethical considerations: Reverse-engineering commercial ROMs can breach copyrights or EULAs depending on jurisdiction and purpose — proceed only for legitimate research, homebrew, compatibility, or preservation where allowed.

Example:
Ghidra requires you to create a custom memory map for the NDS. Without it, the decompiler will produce nonsense like:
