This page is dedicated to guides on reverse engineering the game, to find helpful information about the internals and to assist in creating ASM patches for low level hacks.
Requirements[edit | edit source]
- Ghidra set up with the NSMBU RPX loaded (US v1.3.0 [6B6EF642] is recommended)
- Advanced Users Only! You can alternatively use IDA Pro 7.2+ if you prefer, but this guide will be optimized for Ghidra and you will be on your own to convert steps to IDA equivalents.
- At least a basic understanding of C++ and/or Assembly (preferably PowerPC Assembly)
