It is possible to load TTO/TTD/TTDPatch games in OpenTTD. Look in the list below for further details.

Transport Tycoon (Original) scenarios/savegames

Since SVN revision r15216 (2009-01-23) and officially since version 0.7.0 OpenTTD is able to load any savegame or scenario from TTO. The TTO loader code is based on SVXConverter by Roman Vetter. Possible extensions:

• *.sv1 - Transport Tycoon (Original) saved game
• *.sv2 - Transport Tycoon (Original) saved multiplayer game (2 players)

Transport Tycoon Deluxe savegames

You can load any TTD savegame into OpenTTD. Possible extensions:

• *.sv2 - Transport Tycoon Deluxe saved multiplayer game (2 players)
• *.ss1 - Transport Tycoon Deluxe preset game (included on TTDLX CD)

Transport Tycoon Deluxe scenarios

Most scenarios should work. Copy them into the /scenario directory using the following extensions:

• *.sv0 - Transport Tycoon Deluxe scenario
• *.ss0 - Transport Tycoon Deluxe preset scenario (included on TTDLX CD)

TTDPatch savegames

Warning
Not all TTDPatch savegames can be loaded into OpenTTD!

In particular, if you have used morevehicles, the game will not load. Certain other patches from TTDPatch are also incompatible with OpenTTD. Some patches, like Signals do work in OpenTTD, but others might not be loaded correctly in OpenTTD. Even if a feature is supported in both TTDPatch and OpenTTD, the savegame might not work.
