Opensource clone/remake of "Transport Tycoon Deluxe" (TTD) a PC game
circa 1995.

dL 1 is the new opensource gamedata (2020 release).
dL 2 is version 1.3.1 from 2013, highest working in PowerPC
Tiger/Leopard.
dL 3 is version 1.3.2 from 2013, highest working in Tiger on intel.
dL 4 is version 1.8.0 from 2018, highest for Snow Leopard and Leopard
(intel).

Project began in 2004. Version numbers seems to correlate with its
year, so that roughly in 2009 the versions were 0.9.x and now in 2020
the latest versions are 1.10.x. Project is still going strong at
openttd dot org and each build contains readme files describing
numerous known bugs and other issues, the latest versions have left
PowerPC Mac behind long ago, and so these older versions certainly
meet the criteria for 'abandonware'.

Builds are distributed without the game data. One could import the
data (graphics, sound, music) from any genuine 1990's CD on the game's
PeeCee version, or alternatively, the datasets have also been remade.
The latest (2020) edition of recreated datasets seem to run fine when
plugged into these older executable versions. Copy the data "baseset"
named folder into the folder that has the app file.
