You need to make a folder in your TTD folder (the one with ttdpatch.exe and gamegfx.exe or ttdx.exe) with the name 'newgrf' (without the quotes). Then put all the grf files into that folder.
Now, in your TTD folder (
not the newgrf folder), create a text file called newgrfw.txt. In that folder put lines relating to all the grf files you have put in the 'newgrf' folder like this:
Code: Select all
newgrf/signalsw.grf
newgrf/elrailsw.grf
and so on (you will only need the signalsw.grf file for the presignals).
Now try running TTDPatch.
(By the way, you're missing out on some of the great new features like electrified railways and other new graphics. Post here if you want more information.)
