Project Setup

Note: This guide assumes the use of the recommended Docker setup for building and testing. If you are an advanced user and prefer to set up your own environment, you can refer to the Dockerfile for guidance. A detailed guide for manual setup will be provided in the future.

General Requirements

  • Docker.
  • Dreamcast SDK (Sega Library) Ver.1.55J (Google is your friend).

Setup

SDK Structure

Ensure your SDK files are organized as follows:

├── bin (From disc Vol.1 dc_sdk/bin)
│   ├── binadj.exe
│   └── ...
├── shc (From disc Vol.2)
│   ├── bin
│   ├── include
│   └── lib
└── shinobi (From disc Vol.2)
   ├── driver
   ├── include
   ├── lib
   └── sample

Environment Setup with Docker

  1. Duplicate the .env.example file to create .env:

    cp .env.example .env

  2. Edit the .env file to update the SDK_PATH variable with the absolute path of the SDK files and save the changes.

  3. (Optional) If rebuilding the disc image, uncomment and set the TBG_DISC_PATH variable in .env with the absolute path of the extracted disc image files.

  4. Start a bash shell inside the /app folder:

    ./docker_shell.sh

Build and Test

Building the Binary

Run the following command in the Docker shell:

make

Upon success, the output will include:

Project built :)

Running Unit Tests

After building, run the test suite to validate the code:

./scripts/run_tests.sh

This uses the custom Hitachi SH4 emulator and PHP-based testing framework to ensure decompiled code behaves as expected.

(Optional) Rebuilding the Docker Image

If the Docker image is outdated or causing issues, rebuild it using the docker folder:

docker build -t lhsazevedo/tbg-decomp ./docker
