FFXIV Opcodes

A shared effort to maintain FFXIV opcode mappings

Automated Opcode Correction

This repo contains some (wip) tooling to automate the opcode updating process. How it works and more detailed instructions can be found on the blog post.

Relevant files:

• xiv-opcode-parser.py - IDA script to output a schema generated from the client exe
• schema-diff.py - Python script which takes 2 schemas and attempts to resolve opcode changes automagically.

Proposed Format for Opcode Lists
