This FAQ covers questions about installing OpenTTD.
What do I need to run OpenTTD?
You will need to be running one of the supported operating systems. Then check that your system meets the System Requirements.
How do I install OpenTTD?
Can I use the original TTD files?
In short: No TTD files are needed, free base graphics, sounds and music do exist. But you can still use the base files from TTD:
If you are not using the installer to install OpenTTD, (or are just curious) you need to copy certain files by hand.
Required files; put these in the baseset/ folder:
- Graphic files: trg1r.grf, trgcr.grf, trghr.grf, trgir.grf, trgtr.grf
If you are using the DOS version of TTD to copy the files from, you need the files which are named above but without the "R" on the end, e.g. trg1.grf etc.
- Sound files: sample.cat
- Music files: *.gm
If there is no gm folder, just create it in the main openttd folder, and put the files there. Note that DOS version of TTD does not have *.gm files.
On *nix computers, you need make sure you have permission to view the above files as a normal user, otherwise, you will only be able to run OpenTTD as root.
Why can't I hear sound effects?
You might not have a sound base set installed. See in the Game Options menu if at “Base sounds set” it says “NoSound”. If it does, switch to a different sound set (preferably OpenSFX). If the list does not show anything besides “NoSound”, you need to download a sound base set from the main menu (“Check Online Content”). We recommend OpenSFX.
After you have downloaded a sound base set and enabled it in the game options, you should hear sounds now.
If you still don't hear anything, open the Sound/Music menu in the game and check the sound volume.
Why can't I hear the music?
You might not have a music base set installed. See in the Game Options menu if at “Base music set” it says “NoMusic”. If it does, switch to a different music set (preferably OpenMSX). If the list does not show anything besides “NoMusic”, you need to download a music base set from the main menu (“Check Online Content”). We recommend OpenMSX.
After you have downloaded a music base set and enabled it in the game options, start a game, open the Sound/Music menu, check the music volume and click on the “Play” button.
If that didn't work, your operating system might not support MIDI playback. Consult the manual of your operating system to learn how to support MIDI playback working. If you have done so, restart OpenTTD and try again.
What about nightly builds?
The nightly builds can be used parallel to stable build. Download the latest nightly build archive, then extract it into a new folder without installation required. Just run the binary.
To always play the latest nightly you can use an updater to update to latest Nightly build when you start the OpenTTD.
