Installation Instructions

This document details the steps necessary to build a copy of Pokémon Platinum (EN-US) using this repository.

0. Preliminaries

1. Setting Up Your Development Environment

Windows with MSYS2

  1. Download the MSYS2 installer from the official website and install it on your system.

  2. Once the installation is complete, a terminal should automatically pop up. To update your package registry, enter the following command:

    pacman -Syu

    Press 'Y' when prompted to confirm the update. This process may take a few minutes. Once completed, the terminal will automatically close.

  3. Re-open an MSYS terminal (the pink icon) from your Start Menu, then enter the following commands to install necessary build dependencies:

    echo 'export PATH=${PATH}:/mingw64/bin' >> ~/.bashrc
source ~/.bashrc
pacman -S git meson gcc flex bison mingw-w64-x86_64-arm-none-eabi-{binutils,gcc}

    Press 'Y' when prompted to confirm the installation.

  4. Download the repository.

Windows Subsystem for Linux

Important

If you intend to store your project on the Windows file system (or do not know what that means), then use these instructions, which will guide you through installing WSL version 1. If you intend to use WSL version 2, then instead follow the instructions for Linux.

New Installs

Follow these instructions if you do not have an existing install of WSL.

  1. Open Windows PowerShell as Administrator. Paste (Right Click or Shift+Insert) the following command:

    wsl --install -d Ubuntu

  2. Once the process finishes, you will be prompted to restart your machine. Accept.

  3. After rebooting, reopen PowerShell and run the following command to downgrade WSL to version 1:

    wsl --set-version Ubuntu 1

    WSL version 1 is preferred for most WSL users due to its increased performance when accessing files in the Windows file system.

  4. Open Ubuntu from your Start menu.

  5. Ubuntu will set up its own installation when it runs for the first time. Once finished, it will ask for a username and password as input.

    [!NOTE] When typing the password, there will be no visible response; this is normal, and the terminal is still reading your input.

  6. Update Ubuntu's package registry:

    sudo apt update && sudo apt upgrade

  7. Install build dependencies.

Existing Installs

Follow these instructions if you have an existing install of WSL, specifically Ubuntu.

Older versions of Ubuntu (e.g., 20.04) ship with an outdated version of Python, which is not supported. To remedy this, you can upgrade your existing install to a more recent version of Ubuntu:

  1. Run the following inside Ubuntu:

    sudo apt upgrade && sudo apt full-upgrade

  2. Open PowerShell and run the following commands to restart Ubuntu:

    wsl -t Ubuntu
wsl -d Ubuntu

  3. Re-open Ubuntu and run the following to start a system upgrade:

    sudo do-release-upgrade

    This process may take a long time.

  4. Once Ubuntu is done upgrading, update Ubuntu's package registry:

    sudo apt update && sudo apt upgrade

  5. Install build dependencies.

Install Build Dependencies

  1. Run the following to install build dependencies from the Ubuntu package registry:

    sudo apt install git flex bison build-essential binutils-arm-none-eabi gcc-arm-none-eabi ninja-build

  2. Run the following to install additional dependencies via pip:

    sudo apt install pip
pip install --user meson

    You may see pip respond with a warning saying "The script meson is installed in '/home/<YOUR_USER>/.local/bin', which is not on PATH. To resolve this issue, run the following commands, filling <path/to/install/directory> with the path reported by pip above:

    echo 'export PATH="<path/to/install/directory>:$PATH"' >> ~/.bashrc
source ~/.bashrc

  3. Download the repository.

MacOS

  1. Apple bundles a number of the requisite utilities into Xcode Command Line Tools; to install these, run:

    xcode-select --install

  2. Additional packages can be installed using Homebrew; if you do not already have Homebrew installed, do so. Once Homebrew is installed, run the following commands:

    brew update
brew install gcc@14 meson libpng pkg-config arm-none-eabi-binutils arm-none-eabi-gcc
brew install --cask wine-stable

  3. If your MacOS installation is Monterey (12) or earlier, then you may also need GNU coreutils installed to run the build scripts:

    brew install coreutils

  4. Download the repository.

Linux

Note

Precise packages to be installed will vary by Linux distribution and package registry. A handful of common distributions are listed below for convenience.

[!IMPORTANT] This project requires meson version 1.3.0 or higher. If the version of meson provided by your package manager is out of date, then follow these instructions to get the most recent version.

Once you have installed all the above dependencies, proceed to downloading the repository.

Ubuntu (and other Debian derivatives)

  1. Install wine:

    sudo dpkg --add-architecture i386
sudo mkdir -pm755 /etc/apt/keyrings
sudo wget -O /etc/apt/keyrings/winehq-archive.key https://dl.winehq.org/wine-builds/winehq.key
sudo apt update
sudo apt install --install-recommends winehq-stable

  2. Install the following packages via apt:

    sudo apt install git flex bison ninja-build build-essential binutils-arm-none-eabi gcc-arm-none-eabi pkg-config

  3. Install meson via pip:

    pip3 install --user meson
echo "export PATH=~/.local/bin:$PATH" >> ~/.bashrc
source ~/.bashrc

Arch Linux (and derivatives)

Install dependencies via pacman:

sudo pacman -S git flex bison build-essentials arm-none-eabi-binutils arm-none-eabi-gcc pkg-config wine meson

Fedora (and derivatives)

sudo yum install git flex bison gcc make arm-none-eabi-bintuils-cs arm-none-eabi-gcc-cs pkg-config wine meson ninja-build

Docker

A Dockerfile is provided with the repository should you choose to build the project as a container. If you do not have docker installed on your machine and wish to make use of this feature, follow the instructions here.

Once docker is installed, to the build environment, run:

make clean # only if you have an existing development environment
docker build . -t pret/pokeplatinum

Then, run the following to build the ROM:

docker run -u $USER -w /rom -v .:/rom pret/pokeplatinum make

If you wish to stop using the docker build feature and switch back to a native build environment, then run the following:

docker run -u $USER -w /rom -v .:/rom pret/pokeplatinum make clean

2. Downloading the Repository

From your terminal, navigate to the path in which you will store the repository. Users of WSL 1 should ensure that their target is on the Windows file drive.

git clone https://github.com/pret/pokeplatinum
cd pokeplatinum

3. Specifying a Compiler License

Before building the repository, some final setup is required for the compiler. Create an environment variable called LM_LICENSE_FILE with its value as the path to which you cloned the repository, plus /tools/cw/license.dat. For example, if you cloned your repository to C:\Users\myuser\Desktop\pokeplatinum, then the value would be C:\Users\myuser\Desktop\pokeplatinum\tools\cw\license.dat.

Windows (including WSL 1)

  1. Search for "environment variables" in the Start menu. Click the option which says "Edit the system environment variables".

  2. In the window that opens, click the button that says "Environment Variables..." in the lower right corner.

  3. In the window that opens, click "New..." in the lower right corner.

  4. Input the environment variable name and value as above, then click "OK".

  5. Restart your computer.

Unix Systems

Export the environment variable as above to your terminal profile:

echo 'export LM_LICENSE_FILE="/path/to/pokeplatinum/tools/cw/license.dat"' >> ~/.bashrc
source ~/.bashrc

Users of MacOS should replace ~/.bashrc above with ~/.zshrc.

4. Building the Repository

To build the ROM, run:

make

If everything works, then the following ROM should be built:

If you need further assistance, feel free to ask a question in the #pokeplatinum channel of the pret Discord (see README.md for contact information) or open an issue.

5. Debugger Support

This step is optional, but useful. pokeplatinum ships with support for GDB debugging and a target to build a debug-enabled ROM:

make debug

For convenience, a template launch.json configuration for VS Code is provided in the .vscode folder of the repository.

Due to the nature of the Nintendo DS, use of standard builds of GDB for debugging is insufficient. A fork of binutils-gdb which supports the overlay system employed by the console is available here.

For installation instructions, refer to the README.md.

Troubleshooting FAQ

My Build is Failing After Merging from Main

It is likely that your subprojects are out of date; update them with the following command:

make update

And then try rebuilding.
