Running
OpenTTD will attempt to load everything from ux0:/data/openttd/
The easiest way to populate this is to install the PC version and copy the files across. In the future when network support is re-enabled the content downloader should be functional and this step will be skippable.
For OpenTTD you can use the original Transport Tycoon Deluxe data files (you need to own a Transport Tycoon Deluxe CD). There are also the free alternatives: OpenGFX (graphics), OpenSFX (sound) and OpenMSX (music). These can be installed automatically by the Windows and OS/2 installers. Please refer to the readme for more information.
You can download the free alternatives here: download OpenGFX, download OpenSFX and download OpenMSX.

Controls: The touch screen is currently the only input. The plan is to implement d-pad or rear touch panel for panning and shoulder buttons for zoom level.

The game is set to run at 480x272 scaled to the screen size for the sake of speed. It will run at 960x544 but don't expect more than ~10-15 FPS
