Since version 1.0.0 OpenTTD, installation is simplified enough, the game is completely (play and graphics) open source; everything is included in the installer. To download the latest version of OpenTTD click here.
Installation can be a little complicated, as the Base graphics are not distributed with the game. So beside downloading the game, you need to obtain a set of base graphics as well.
Currently, there are two sets of base graphics that OpenTTD can use:
- OpenGFX, the official open source graphics set made by the OpenTTD team.
- The original base graphics from the Transport Tycoon Deluxe (TTD) CD. As opposed to OpenTTD, TTD is not free software.
InstallationSelect the installation instructions for the base graphics set you chose and your operating system:
(If you have access to the TTD base graphics and can't decide what base graphics to use, install the game using the TTD base graphics. OpenGFX can easily be installed afterwards. However, the easiest way is to install the game with all files from the start: TTD base graphics, OpenGFX, OpenMSX and OpenSFX files.)
Installation on Windows
Using TTD base graphics
1. Get Transport Tycoon Deluxe for Windows. If you don't have your CD, see Google. Note: The original graphics are copyrighted, it may be illegal (in some countries) to download them.
2. Download the Windows installer for OpenTTD from the downloads page.
3. Install OpenTTD. Chose the components OpenTTD and Copy data from TTD CD-ROM.
4. Tell OpenTTD where to find your TTD files; it should find them automatically if you used the TTD Windows installer, if not point it to the TTD CD in the drive.
5. Chose the folder in which to install OpenTTD.
6. Select the Start Menu folder in which you would like to create the program's shortcuts.

Using OpenGFX base graphics

4.4. Save the changes you made and run OpenTTD.

Files from TTD
If you're installing OpenTTD with the TTD base graphics, OpenTTD requires several original game files from your Transport Tycoon Deluxe installation CD.
The following files are mandatory. You need to copy them to the /baseset directory, which is in your personal OpenTTD directory. These files contain the graphics and the sound effects:
Additionally, you may want to copy the original game music. To accomplish that, you need to copy the /gm/ folder from the TTD CD to the /baseset in your personal OpenTTD directory.
There are a few ways to get these files:
- Copy the folder and files from the TTD game CD to your OpenTTD /data folder.
- Unzip a TTD installation zip file, and copy the folders.
- Install TTD for Windows in another directory and then copy the folders.
Installing sound and music
Chances are, your OpenTTD installation already has sound and music. If it doesn't, we recommend to install OpenSFX and OpenMSX from the in-game content downloader. You need an Internet connection for this. After the download, go to “Game Settings” and select these base sets for sounds and music.
For music to work, your system needs to have MIDI playback support. Most systems should support it out of the box, but if not, consult the manual of your operating system to learn how to get MIDI support.
You can control music and sound playback in-game with the Sound/Music menu. Click the “Play” button to start music playback.
AI is neccessary in order to get competing companies in singleplayer. Without AI, the computer won't launch any competing companies, and your company will be alone.
In the main menu, click on the “AI” button, and then on “Download extensions”. Again, you need an Internet connection for this to work. There are a lot of AIs to choose from. We recommend SimpleAI for a start, as it is the most stable one. In the AI menu, you can choose how many computer players there will be in your game.
