Decompiling an NDS ROM isn't a one-click process. It typically follows these stages: How to reverse engineer your favourite game

This is a massive improvement over raw hex, but it lacks semantic meaning. What does FUN_0201b2e4 do? What does the return value represent? The human reverse engineer must rename functions and variables, creating a Symbol Map. Decompiling an NDS ROM isn't a one-click process

However, true full-decompilation of arbitrary NDS ROMs remains an unsolved automation problem. Most successful efforts are and game-specific (e.g., Pokémon Diamond , Super Mario 64 DS ).
The true decompiler (e.g., Ghidra’s built-in decompiler or the now-commercial Hex-Rays for IDA) attempts to lift assembly into a pseudo-C representation. For the NDS, this process is fraught with difficulty. The decompiler must identify function prologues and epilogues, reconstruct loops, infer data types, and recognize compiler idioms.
