With this patch you can create a new « GT4.VOL » file by integrating four TT tracks instead four circuits of GT4:

 

 

This patch works only with the PAL and the NTSC/U/C versions of GT4.  It doesn’t work with the other NTSC versions (the Asian ones).

 

The common instructions are written in black.

The specific instructions for the PAL version are written in blue.

The specific instructions for the NTSC/U/C version are written in green.

 

Here is the procedure :

 

Step 0: Pre required

You must have a commercial version of GT4.

You must know how to build and how to run a GT4 backup game.

You must have enough free space on your hard disk to build the new « GT4.VOL » file:

- for the PAL version, at least 6.2 Gb of free space.

- for the NTSC/U/C version, at least 5.0 Gb of free space.

 

Step 1: Install 7-Zip

If you don’t have it, you must download and install the free software 7-zip : http://www.7-zip.org/

 

Step 2: Check the size of the « GT4.VOL » file

Insert the GT4 DVD in your DVD reader.

Check the size of the « GT4.VOL » file on the DVD:

- for the PAL version, you must find 3 084 849 152 bytes.

- for the NTSC/U/C version, you must find 2 459 506 688 bytes.

 

Step 3: Create the VOL parts

Create a temporary directory on your hard disk.

Launch 7-zip, go on the DVD and select the « GT4.VOL » file.

With a right click, select « Split file ... », then select the temporary directory, and in the field « Split to volumes, bytes: » put exactly the value: 4194304, then launch.

Wait for the end of the task (several minutes).

 

Step 4: Check the size of the VOL parts

For the PAL version:

When the task is finished, check that you have 736 files in the temporary directory, numbered from « GT4.VOL.001 » to « GT4.VOL.736 ».

Check the size of the files « GT4.VOL.001 » and « GT4.VOL.735 »: you must find 4 194 304 bytes.

Check the size of the file « GT4.VOL.736 »: you must find 2 035 712 bytes

For the NTSC/U/C version:

When the task is finished, check that you have 587 files in the temporary directory, numbered from « GT4.VOL.001 » to « GT4.VOL.587 ».

Check the size of the files « GT4.VOL.001 » and « GT4.VOL586 »: you must find 4 194 304 bytes.

Check the size of the file « GT4.VOL.587 »: you must find 1 644 544 bytes

 

Step 5: Get the new VOL parts

For the PAL version, download the 9 following files:

http://vrrroummm.free.fr/gt4/patch/pal_v1.0/GT4.VOL.pal.183.rar

For the NTSC/U/C version, download the 9 following files:

http://vrrroummm.free.fr/gt4/patch/ntscuc_v1.0/GT4.VOL.ntscuc.005.rar

http://vrrroummm.free.fr/gt4/patch/ntscuc_v1.0/GT4.VOL.ntscuc.115.rar

http://vrrroummm.free.fr/gt4/patch/ntscuc_v1.0/GT4.VOL.ntscuc.123.rar

http://vrrroummm.free.fr/gt4/patch/ntscuc_v1.0/GT4.VOL.ntscuc.124.rar

http://vrrroummm.free.fr/gt4/patch/ntscuc_v1.0/GT4.VOL.ntscuc.127.rar

http://vrrroummm.free.fr/gt4/patch/ntscuc_v1.0/GT4.VOL.ntscuc.128.rar

http://vrrroummm.free.fr/gt4/patch/ntscuc_v1.0/GT4.VOL.ntscuc.129.rar

http://vrrroummm.free.fr/gt4/patch/ntscuc_v1.0/GT4.VOL.ntscuc.130.rar

 

Step 6: Replace the old VOL parts with the new ones

Open each rar file (with 7-Zip for example), extract the « GT4.VOL.??? » file which is inside and put it instead the existing file in the temporary directory.

 

Step 7: Build the new « GT4.VOL » file

Launch 7-Zip, go in the temporary directory, and select the « GT4.VOL.001 » file.

With a right click, select « Combine files ... », select a different directory if needed, then launch.

Wait for the end of the task (several minutes).

 

Step 8: Check the size of the new « GT4.VOL » file

When the task is finished, check the size of the new « GT4.VOL » file:

- for the PAL version, you must find  3 084 849 152 bytes.

- for the NTSC/U/C version, you must find  2 459 506 688 bytes.

Delete the 736 part VOL files, numbered from « GT4.VOL.001 » to « GT4.VOL.736 ».

Delete the 587 part VOL files, numbered from « GT4.VOL.001 » to « GT4.VOL.587 ».

 

That’s all.

Now you can build a GT4 backup game with the new « GT4.VOL » file.

Have fun.

VV.

 

PS: please don’t ask me how to build a GT4 backup game and how to run it, it’s not my matter. I’ll not answer this kind of questions.
