Decompiler | Nds

If you want to “decompile” an NDS game:

NDS decompilation is a semi-manual, expert-driven software archaeology process , not an automated decompiler task. The term “NDS decompiler” is a useful shorthand for the toolchain and methodology, not a standalone tool. nds decompiler

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.
