OpenTTD

OpenTTD emulates Transport Tycoon Deluxe. It reads 37 files, none of them required: it starts games without them.

The app reads its files from this folder:

Technical notes

Open source reimplementation of Transport Tycoon Deluxe. RetroPie installs the distribution's openttd package (14.1 on Debian trixie, 13.0 on bookworm), whose recommends pull in the OpenGFX, OpenSFX and OpenMSX base sets, and moves the user's openttd folders under ~/.config, ~/.local/share and ~/.local into its ports configuration. This profile reads the 14.1 tag.

Graphics, sounds and music come from base sets. Each set is a .obg, .obs or .obm description found in the baseset folder of any search path, naming its files and their MD5. A file is looked up in the baseset folders under the path the description gives, with a lowercase retry. A set missing any file is neither listed nor picked automatically. A file whose MD5 differs keeps the set usable and is reported as corrupt at start. For a GRF the MD5 covers the data section, which is the whole file in the original container format. ref: src/base_media_func.h:84-158, src/base_media_func.h:345-372, src/gfxinit.cpp:475-495, src/fileio.cpp:215-230, src/gfxinit.cpp:125-136, src/newgrf_config.cpp:255-277

The descriptions of the original game's files ship with OpenTTD in media/baseset: orig_dos.obg, orig_dos_de.obg and orig_win.obg for the graphics, orig_dos.obs and orig_win.obs for SAMPLE.CAT, orig_dos.obm, orig_win.obm and orig_tto.obm for the music. ORIG_EXTRA.GRF, also named by the graphics sets, is built and installed with OpenTTD. The MD5 values below are the ones those descriptions carry.

Without any usable graphics set OpenTTD offers to download OpenGFX from its content service, and fails with no network. A missing sound or music set falls back to no_sound.obs and no_music.obm, which ship with it. ref: src/openttd.cpp:717-745, src/openttd.cpp:781-812, src/bootstrap_gui.cpp:362-371

Paths below are relative to an OpenTTD search path, the personal data folder named in the data folder being the usual one. Base set files sit in its baseset folder. ref: src/fileio.cpp:48
