The source files are assembled into a rom using [**rgbds**](https://github.com/bentley/rgbds). These instructions explain how to set up the tools required to build. # Linux Python 2.7 is required. ```bash sudo apt-get install make gcc bison git python python-pip pip install pypng git clone https://github.com/bentley/rgbds cd rgbds sudo make install cd .. git clone --recursive https://github.com/pret/pokecrystal cd pokecrystal ``` To build **pokecrystal.gbc**: ```bash make ``` # Mac In **Terminal**, run: ```bash xcode-select --install sudo easy_install pypng git clone https://github.com/bentley/rgbds cd rgbds sudo make install cd .. git clone --recursive https://github.com/pret/pokecrystal cd pokecrystal ``` To build **pokecrystal.gbc**: ```bash make ``` # Windows To build on Windows, use [**Cygwin**](http://cygwin.com/install.html). Use the default settings. In the installer, select the following packages: `make` `git` `python` `python-setuptools` `gcc-core` `libsasl2-3` `ca-certificates` Then get the most recent version of [**rgbds**](https://github.com/bentley/rgbds/releases/). Extract the archive and put `rgbasm.exe`, `rgblink.exe` and `rgbfix.exe` in `C:\cygwin\usr\local\bin`. In the **Cygwin terminal**: ```bash lynx -source bootstrap.pypa.io/get-pip.py | python pip install pypng git clone --recursive https://github.com/pret/pokecrystal cd pokecrystal ``` To build **pokecrystal.gbc**: ```bash make ```
