# Jet Set Radio Future: early matching Xbox decompilation

> An early matching decompilation of the North American standalone Xbox release of Jet Set Radio Future, hosted on Codeberg. Contributors delink default.xbe into per-source object files in Ghidra, then write C++ that compiles to matching objects with Visual C++ 7.0, compared with objdiff. Its README reports 1.50% of the XBE decompiled so far and disallows contributions made with large language models.

## Requirements & limits

- **Prerequisites:** Contributors need default.xbe from the NTSC-U standalone Jet Set Radio Future disc. The repository supplies reconstructed sources and Ghidra import listings, without the game executable or assets.
- **Prerequisites:** Use Microsoft Visual C++ 7.0 (Visual C++ .NET 2002), Git, Java 21 or newer, Ghidra 12.0.3 with XboxDev XBE and ghidra-delinker-extension v0.8.0, and objdiff 3.8.1 with objdiff-cli on PATH. Outside Windows, run the compiler through Wine. The Microsoft compiler is separately licensed.
- **Limits:** The project reports 1.50% of the XBE decompiled; linking a Windows executable and repackaging it for Xbox remain planned steps. No rebuilt executable or playable build is available yet. The Ghidra getting-started guide has TODO import instructions.
- **License:** The repository is CC0 1.0; its Ghidra scripts directory includes GPL-3.0 text. Game and toolchain rights remain separate. The README prohibits contributions made with large language models or generative AI and merge requests from agent-driven forks.
