Editing OpenTTD (section)

===Prior modifications to ''Transport Tycoon Deluxe''===
There was a prior attempt to modify Transport Tycoon Deluxe to run on more modern operating systems. ''OpenTTD'' was preceded by a commercial conversion of ''Transport Tycoon Deluxe'' to run on [[Windows 95]]. It was created in 1996 by the FISH technology group, but Nola released in 1999 as part of a compilation of older ''Tycoon'' games. This release was still greatly restricted in operating systems and computer architectures it could run on.

Similarly, there was an earlier success aiming to open ''Transport Tycoon Deluxe'' to modification by users. ''[[TTDPatch]]'', initially created by Josef Drexler in 1996–97 and still being developed in 2010, changes the behaviour of ''Transport Tycoon Deluxe'' as it is running, to introduce many new features to the game, such as new graphics, vehicles, industries, etc. ''TTDPatch'' is restricted by the same operating system and computer architecture limits as ''Transport Tycoon Deluxe'' and has limited control over what features of the game can be altered.
