Using Ghidra

Ghidra gets a lot of flak in N64 Decomp circles; it was not designed to create matching MIPS code (in the way that mips2c was), but it can still be useful to get an idea of what is going on in a function - especially when loops are involved.

NOTE: This page will not cover installing/setting up Ghidra - Google is your friend.

Install the N64 ROM Loader Extension (File -> Install Extension...)

In order to reverse engineer game code, you want to load in the extracted code:

make decompress
cd game/rzip/code
cat 0*.bin > game.decompressed.bin

N64 ROMs are loaded in with MIPS:BE:64:64-32addr:default, when loading in this file pick the following language: MIPS | 64-32addr | 32 | big | o32
