Here is what you have to do:

1. Download TC.zip (see downloads section) and extract it to C:\TC
2. Download wolfsrc.zip (see downloads section) and extract it to C:\SOURCE\WOLF and also to C:\TC\BIN
3. Download wolfobj.zip (see downloads section) and extract it to C:\SOURCE\WOLF
4. Unzip another copy of wolfobj.zip to a separate directory (preferably in a subfolder on your desktop) and copy the files ID_CA.OBJ and ID_SD.OBJ to the directory C:\TC\BIN\OBJ (overwrite.)
5. Go to C:\TC\BIN\OBJ and make sure the attribute "Read Only" is on ID_CA.OBJ and ID_SD.OBJ
6. Go to the directory C:\TC\BIN and start TC.EXE
7. Click on Project | Open Project.
8. With your mouse, locate the file C:\TC\BIN\WOLF3D.PRJ and click OK.
9. Click on Options | Directories.
10. Make sure that the "Include Directory" reads C:\TC\INCLUDE, the "Library Directory" reads C:\TC\LIB, the "Output Directory" reads either OBJ or C:\SOURCE\WOLF, (actually, I think it can be any directory you want, that is the directory where the executable is made you when compile the code successfully) and the "Source Directory" reads C:\SOURCE\WOLF
11. Click Compile | Link
12. Click Compile | Make
13. Click Compile | Compile

What ever you do, DO NOT click Compile | Build All because it will miscompile a few obj files and in resault mess up the graphics in the game. But if you did click Compile | Build All, then go to the troubleshooting section and look for the appropriate question.

Other notes:

One more thing that you need to make sure of is that you set the following parameter in your AUTOEXEC.BAT file:

PATH C:\TC\BIN

If my current AUTOEXEC.BAT file contains the following code:

@ECHO OFF
PROMPT $P$G
PATH C:\WINDOWS;C:\DOS

Then I would change the code so the path line reads:

PATH C:\WINDOWS;C:\DOS;C:\TC\BIN

Hence the code for my AUTOEXEC.BAT file would look like this:

@ECHO OFF
PROMPT $P$G
PATH C:\WINDOWS;C:\DOS;C:\TC\BIN

Another thing to remember is that the AUTOEXEC.BAT file is located in the root directory of drive C.

You will need to restart your computer after this, or just run AUTOEXEC.BAT

WinZip VS. PkUnzip

If you are using WinZip for Windows to unzip Wolfobj.zip Wolfsrc.zip and TC.zip then do as you normally do with unzipping them, you shouldn't have any problems with it. But if you are using PkUnzip, you are going to have to do things a little differently. To unzip these particular files, you are going to have to use the -d parameter. For example, if you wanted to unzip TC.zip to C:\TC then you would type in the following at the DOS Prompt:

pkunzip -d tc.zip c:\tc

By doing this, PkUnzip will make sure to include all the subdirectories located in the zipped file. The same thing goes for the other two zip files I mentioned above.

When you are ready to run your new Wolf3D.exe

Unzip a fresh copy of the full version of Wolfenstein 3D to a new directory. Go to the directory you specified for the "Output Directory" (see above), click View | Refresh. Then copy your new Wolf3D.exe to the directory you just unzipped Wolfenstein 3D to. Then download vgafiles.zip (see downloads section) and unzip it to the same directory as the fresh copy of Wolfenstein 3D (overwrite.) Then, of course, use your new executable.

PLEASE ALSO NOTE THAT ALL YOUR WOLF3D FILES MUST BE V1.4
