DaleStan: /* Compiling the grf */ 1) -f is poorly documented for a reason. Please keep it that way. 2) You encode a grf, not an nfo.

‎Compiling the grf

PikkaWiki: /* Getting set up */ why would you create a batch file just to run a single command that you're never going to want to run again? ;) I will add a section on batch files, though... good idea :o

Bennythen00b: I added a better description of how to decompile a .grf file.

 Hopefully you can work out how to do this yourself.  However, here's a few tips:

 ==Getting set up==
 *Install grfcodec into a directory under/near your TTD directory.
-*Copy trg1r.grf to this directory (and, if you like, the other default grfs) and decompile them with grfcodec. (Open a new document in Notepad and copy paste this line into it: '''grfcodec -d trg1r.grf -p2'''. Save the document as *Whatever you want*.bat. The name isn't important, but remember the ".bat" Now double click the document you just made.).

 **Resist the temptation to decode any other grf and have a look at what comes out.  It will not be useful to you at this point.  Believe me.
 *Install NFOrenum into <grfcodec directory>/SPRITES, which should have been created when you decoded trg1r.grf.
