The world of NDS reverse engineering is rich with possibilities, from creating custom patches and translation mods to uncovering the secrets of classic game design. What will you discover first?
The "Gold Standard" of NDS decompilation is creating a "Matching Build." This involves writing C code that, when compiled, produces the exact same binary as the original rom.
This is where the actual "decompilation" happens. nds decompiler
CrystalTile2 is arguably the most versatile Swiss Army knife for NDS ROM hacking. It's a single application that combines a hex editor, tile editor, and, crucially, a disassembler. Its disassembler is designed to work seamlessly with other features, allowing users to jump from a specific address in the tile viewer to the corresponding disassembly. It is also noted for its ability to handle the NDS file system natively, letting you browse, extract, and disassemble individual files without needing external tools.
Install Ghidra and download a community-made (e.g., Ghidra-NDS-Loader ). Install the plugin via File -> Extension inside Ghidra. The world of NDS reverse engineering is rich
It features a robust, built-in decompiler that translates ARM machine code into highly readable C code.
It offers the most accurate decompilation, superior analysis, and an extensive plugin ecosystem. Drawback: It is very expensive. 3. AetiasHax/ds-decomp This is where the actual "decompilation" happens
Begin with a specific, narrow goal: locate a piece of text, understand a game mechanic, or find where a particular variable is stored. Use No$GBA breakpoints to halt execution when a value changes, then trace back to the code responsible. Follow tutorials like "Reverse Engineering a DS Game" from StarCube Labs, which provides a primer on loading DS ROMs into Ghidra and setting breakpoints.
