Use the following steps to build Tuxemon on Ubuntu for the GCW-Zero from source:
1. Install git and squashfs tools with the following command: sudo apt-get install git squashfs-tools
2. Clone the latest development version of Tuxemon with Git: git clone -b development https://github.com/Tuxemon/Tuxemon.git
3. Modify the Tuxemon configuration file to set the resolution for the GCW-Zero: sed -i 's/resolution_x.*/resolution_x = 320/g' Tuxemon/tuxemon/tuxemon.cfg
sed -i 's/resolution_y.*/resolution_y = 240/g' Tuxemon/tuxemon/tuxemon.cfg
sed -i 's/fullscreen.*/fullscreen = 1/g' Tuxemon/tuxemon/tuxemon.cfg
4. Copy the correctly sized icon file for the GCW-Zero to the correct location: cp Tuxemon/tuxemon/resources/gfx/icon_32.png Tuxemon/tuxemon/resources/gfx/icon.png
5. Fetch all of Tuxemon's dependencies and copy them into the tuxemon directory:
# Clone the latest version of PyTMX
git clone https://github.com/bitcraft/PyTMX.git
cp -r PyTMX/pytmx Tuxemon/tuxemon/
# Download PyTMX's dependencies
wget "https://pypi.python.org/packages/source/s/six/six-1.9.0.tar.gz#md5=476881ef4012262dfc8adc645ee786c4"
