Getting started

Introduction to decomp

• What we are doing
• Structure of the code

Pre-decompilation

• Introduction to git
• Building the repo (follow the instructions in the README.md)
• Most of us use VSCode. Some useful information is here.

• Choosing a first actor (You want something small that has simple interactions with the environment. A simple NPC can also work, and is what we will use as an illustration for most of the tutorial. There is a collection of actors we think are suitable for beginners on the spreadsheet or Trello)

Decompilation

• Begining decompilation: order, Init and the actor struct

  • Order of decompilation
  • Init and common actor features
    • Initchains
    • Actors and dynapoly actors
    • Colliders
    • Skelanime

• The rest of the functions in the actor

  • Order of decompilation
  • Action Functions and other functions

• Draw functions

• Data, migration and non-migration

  • Importing the data: early and late
  • Segmented pointers
  • Fake symbols
  • Inlining

• Documenting a decompiled file

Object Decompilation

• Object files
• How we decompile objects

After Decompilation

• See the CONTRIBUTING.md for most of the details for submitting PRs. Remember to format again after making adjustments from reviews!
• More information about specific preparations is in this document.

Appendices

• Types, Structs and Padding (a miscellany of useful stuff)
• Advanced control flow (an example of a more complex function which mips2c is not so good at)
• Using the diff script and the permuter (using the diff script and the permuter to match something)
  • control flow (branches) -> instruction ordering -> register allocation -> stack
• [Helper scripts] TODO: link when merged

To be written, maybe

• How we use git and GitHub
• Some notes on the basic structure of N64 MIPS
• Glossary
• Conventions
