Transport Tycoon Deluxe file missing?
 

Hi,
I'm on xp, and I've done the registery and rebooted. When I run the game it says "dplay.dll does not exist" and stops.

Help would be appreciated thanks.

Copy a file called "dplayx.dll" from Windows\system32 directory in the game directory and renamed it to "dplay.dll" (or google & download dplay.dll).

Or you could try the open source clone instead:

Thank you. I copied the file and renamed it and am now hopelessly addicted to TTD again.
