jeff Project Template

If starting a new Xbox 360 decompilation project, this repository can be used as a scaffold.

See jeff for background on the concept and more information on the tooling used.

References

• Discord: GC/Wii Decompilation (While not for Xbox 360, GC/Wii also uses PPC)
• objdiff (Local diffing tool)

Although this template is meant for Xbox 360 projects, it has been forked from a GC/Wii template, and intentionally follows the same structure. Nearly all active GC/Wii decompilation projects use this structure, and will be useful for reference. A list of active GC/Wii projects can be found on decomp.dev.

Features

• Few external dependencies: Just python for the generator and ninja for the build system. See Dependencies.
• Simple configuration: Everything lives in config.yml, symbols.txt, and splits.txt.
• Multi-version support: Separate configurations for each game version, and a configure.py --version flag to switch between them.
• Feature-rich analyzer: Many time-consuming tasks are automated, allowing you to focus on the decompilation itself.
• No manual assembly: decomp-toolkit handles splitting the XEX into relocatable objects based on the configuration. No game assets are committed to the repository.
• Integration with objdiff for a diffing workflow.

COMING SOON(TM):

• Progress calculation and integration with decomp.dev.
• CI workflow template for GitHub Actions.
