openttd.cfg è il file di configurazione che OpenTTD usa per memorizzare tutte le sue impostazioni. Utilizza la struttura ini-file che è un archivio comune di dati di configurazione in molte applicazioni. Il file ha tutte le variabili organizzate in gruppi per facilitarne la modifica. Attualmente il giocatore interagisce con esso tramite la finestra delle Impostazioni o le Opzioni di gioco e solo in pochi casi deve modificarlo direttamente, per esempio se si vuole impostare un tipo o dimensione di font personalizzato. Anche se gestiscono le stesse impostazioni, non c'è sempre una diretta corrispondenza tra i gruppi del file openttd.cfg le sezioni della finestra delle impostazioni. Ad ogni riorganizzazione di quest'ultima non è coincisa una riorganizzazione dei gruppi nell openttd.cfg che ha quindi mantenuto l'assetto originario ereditato da TTD salvo per le implementazioni successive.

É situato in:

 Win XP : "C:\Documents and Settings\<username>\My Documents\OpenTTD" or "%UserName%\Documents\OpenTTD"
 Vista/7/8/10: "C:\Users\<username>\Documents\OpenTTD"
 Linux  : "~/.openttd" or "~/.config/openttd/openttd.cfg"
 Mac OS X  : "~/Documents/OpenTTD"
 Any OS  : OpenTTD installation folder (deve essere creato dopo l'installazione, prima della primo avvio di OpenTTD)

Puoi modificare il file utilizzando qualsiasi editor di testo (salvandolo come ANSI). Ogni volta che si esce da OpenTTD, tutte le modifiche al file openttd.cfg vengono automaticamente salvate.
