We now have generation of an import library for linking against the Xbox kernel, linking together an .exe, and converting it to an .xbe via cxbe. Some further development of tooling aside (including filling in some features in cxbe to better match the original JSRF executable), all that remains now is to write decompiled code.

# Jet Set Radio Future North American Standalone Decompilation
|
|
A matching decompilation of the Xbox game Jet Set Radio Future.
|
|
|
|
## Progress
|
|
- Delinking progress: 1.02% (26359 out of 2574172 bytes in XBE address space)
|
|
- Decompilation progress: 18.7% (31 out of the 166 functions delinked so far)
|
|
- **Estimated total progress: 0.19%** (previous two multiplied together)
|
|
|
|
## Roadmap
|
|
The approach of this decompilation is to:
|
|
1. Delink the JSRF executable (`default.xbe`) into object files, each
|
|
representing a single C++ source file
|
|
2. Decompile the object files into C++ code that produces matching object files
|
|
3. Link the object files into a Windows executable (n.b. this would not be
|
|
runnable on Windows)
|
|
4. Repackage the Windows executable into a working Xbox executable
|
|
|
|
We are currently engaging in the first two steps simultaneously, decompiling
|
|
code as it's delinked. Further details on these steps can be found in the
|
|
[contribution guide](documentation/gettingstarted.md). Step 3 uses the linker
|
|
from the same Visual C++ 7.0 already used to compile object files. Step 4 uses
|
|
the `cxbe` tool found in e.g. [nxdk](https://github.com/XboxDev/nxdk).
