(svn r14563) -Fix [FS#2395]: in the case that an industry NewGRF, a shared TTDPatch and
OpenTTD feature with it's origin in TTDPatch to replace/add/change vehicles
(including e.g. maximum speed, graphics and introduction year), stations,
bridges, industries, town houses or any other graphics used by either
TTDPatch or OpenTTD, would tell that building an industry is okay, which
is queried using a so-called callback that allows the NewGRF author to
test all kinds of information about the neighbourhood where the industry
might get build, it would corrupt, i.e. overwrite with invalid data, the
structure that is used to build up an error message. This then might result
in trying to resolve an invalid StringID, an internal numeric representation
of all translateable strings, which would in it's turn trigger a safety
check that is added to ensure invalid StringIDs are never resolved.
To install OpenTTD, you should drag the game to any location you want and in that folder, you should create a folder called "data". It should contain:
sample.cat
trg1r.grf
trgcr.grf
trghr.grf
trgir.grf
trgtr.grf
(Alternatively you can use the TTD GRF files from the DOS version: TRG1.GRF, TRGC.GRF, TRGH.GRF, TRGI.GRF, TRGT.GRF. A few minor graphical glitches with the DOS graphics remain. E.g. the autorail button in the rail toolbar doesn't look as nice as with the Windows graphics.)
You should also use the data folder to add any custom grf files if you like
if you want music, you can add a GM folder and add all .gm files from TTD inside it
If you want to use the scenarios, you can copy the scenario folder as well. If you already have one, just copy the content so you don't overwrite old ones that have been removed.
In the end, you should have a folder containing:
OpenTTD (the actual game)
data (containing the grf files)
GM (optional for music)
scenario (optional pregenerated maps)
The game adds some items by itself when it runs, like a save folder and a setting file
