# SSX (2000) Decompilation
|
|
|
|
This repository contains a work-in-progress functional decompilation of SSX (2000) on the PlayStation 2.
|
|
|
|
The binary being used is the US game binary, original filename `SLUS_200.95`, however multiple game builds might be considered later.
|
|

# FAQ
|
|
|
|
## Why not a matching decompilation?
|
|
|
|
While this was briefly considered, the time it would take is far greater, let alone the fact that tooling for matching decompilations
|
|
for the PS2 is nearly nonexistant and would have to be written from scratch specifically for this project.
|
|
|
|
Later on, it might be worth considering again, however, for now, a functional decompilation will mean faster, more promising results.

## How can I help?
|
|
|
|
Contributions are greatly accepted, if not valued in the early stage of this project.

Documentation for the styleguide used in the project is below, and a Ghidra server for the project is also available.

# Building
|
|
|
|
You will need:
|
|
|
|
- A Linux machine
|
|
- CMake
|
|
- the SCE PS2 SDK (PS2SDK support may be considered later), 2.5.5 at least.
|
|
|
|
You'll need to export SCE to point to your SCE root. This is always /usr/local/sce, and some of the scripts assume so, but for posterity, I don't hardcode it.
|
|
|
|
The SCE EE and IOP tools will also need to be in your PATH.
|
|
|
|
## Build Hacks
|
|
|
|
The crt0.s needs to be built in $SCE/ee/lib, due to a weird issue (and CMake building binaries before the actual compilation stage).
|
|
|
|
This can be done like so (do not run this as root. You should have $SCE chowned to yourself.):
|
|
|
|
```bash
|
|
$ ee-gcc -c -xassembler-with-cpp crt0.s -o crt0.o
|
|
```
|
|
|
|
Finally, you'll need to then edit app.cmd (in the same directory) to replace all indirect mentions of `crt0.o` with the path to the crt0.o you just assembled. This is the final hack in the build process.
|
|
|
|
## Actually Building
|
|
|
|
Then, it's as easy as:
|
|
|
|
```bash
|
|
$ cmake -Bbuild --toolchain cmake/Toolchain/ps2.cmake
|
|
$ cd build
|
|
$ make
|
|
```
|
|
|
|
Note that the Ninja CMake generator does not work with the SCE SDK, and should not be used if using it.
