Playstation Music and Unfinished Business expansion
By Xazuki
This guide covers:
  • Restoring the Playstation music that is absent from the Steam version of Tomb Raider.
  • Installing the expansion pack Tomb Raider: Unfinished Business.

Playstation Music
The Playstation version of Tomb Raider contained extra music that played at certain points during the game. These pieces of music added a lot to the ambience and setting of the game but are unfortunately not included in the PC version of Tomb Raider. This guide adds them to your Steam version of Tomb Raider so the extra music will play just like the Playstation version.

Tomb Raider: Unfinished Business expansion pack
A PC only expansion pack was released for free to owners of the PC version of Tomb Raider. The expansion pack itself is known as Tomb Raider: Unfinished Business or sometimes Tomb Raider Gold: The Shadow Of The Cat. The expansion contains four new levels of a higher difficulty then the regular game. This guide will let you install the expansion pack for your Steam version of Tomb Raider without breaking the original Tomb Raider.
Downloading the required file
Both the Playstation Music and the Unfinished Business expansion come from the same setup file created by Gidierre from the Tomb Raider Forums. The files we will use to add the Playstation music and the Unfinished Business expansion are created by this setup file.

Download the Tomb Raider 1 & Unfinished Business installer[www.tombraiderhub.com] which is hosted on the Tomb Raider Hub website. After downloading, extract everything from the zip file and run the Tomb Raider installer setup.

This setup file will create a duplicate Tomb Raider installation at "C:/tombraider" with working music and expansion pack. This installation can either be used directly or you can use its files to patch the Steam version of Tomb Raider (more on this later).

There are several options you can tick while installing:

  • Install nGlide - This adds some graphical enhancements. If you intend to patch your Steam version of Tomb Raider you will instead need to follow the Visual Improvements guide, which is located at the end of this guide, after you have finished getting the music and expansion working.
  • Install JoyToKey - JoyToKey is an extra program that lets you assign keyboard button presses to a joypad, allowing you control Tomb Raider with your joypad. It is up to you whether you want to install this or not.
Some users have also reported that after installation they needed to run the additional file Tomb Raider 1 installer Patch.

The files have now been created, however, the rest of this guide details how to instead use the files from that setup to patch your own Steam version of Tomb Raider. There are certain benefits to patching your Steam version of Tomb Raider such as:
  • You can run Tomb Raider directly from your Steam games list with the Playstation music included.
  • The Steam overlay is present and correctly identifies you are playing Tomb Raider, allowing you to take Steam screenshots, view Steam guides, etc.
  • Steam will correctly count your hours played in Tomb Raider.
  • You don't need the secondary duplicate installation of Tomb Raider at "C:/tombraider", which saves substantial space.
  • Unfinished Business can be added as a non-steam shortcut so it appears in your list of Steam games.
Patching the Steam version is a more complicated process that I will outline in the rest of this guide. If you don't feel comfortable copying and renaming files, then just use the version of Tomb Raider created at "C:/tombraider" and ignore the rest of this guide.
Adding the Playstation music
NOTE: During this part of the guide you will need to be able to see file extensions on your files to be able to rename them. If you can't see the file extensions (.exe for example) on the files in your folders, you need to toggle the Windows option Show or hide extension for known file types[windows.microsoft.com].
  • Go to the newly created folder "C:\tombraider" on your computer.
  • Select and copy the two files tombeng.bin and tombeng.cue.
  • Go to the location of your Steam Tomb Raider installation. By default this should be located somewhere similar to: "C:\Program Files\Steam\steamapps\common\Tomb Raider (I)\".
  • Paste the two files into this folder.
  • In the Steam Tomb Raider folder, delete the file GAME.DAT.
  • Rename the file tombeng.cue to GAME.DAT .
  • Return to the Tomb Raider installation at "C:\tombraider" and copy the file tomb3dfx.EXE.
  • Go back to your Steam Tomb Raider installation and this time go into the TOMBRAID folder.
  • Delete the existing tomb.EXE file.
  • Paste the tomb3dfx.EXE file in it's place and then rename it to tomb.EXE .
This will have enabled the Playstation music for the Steam version of Tomb Raider and you will be able to hear it at certain points in the game just like the Playstation version.

NOTE: If you want to revert to the default Tomb Raider files for any reason, such as the mods not working correctly, then right click Tomb Raider I in your Steam library and select Properties. Then click the Local Files tab and then Verify Integrity of Game Cache. This will force Steam to redownload any files that have been modified. You may need to delete the modified files (GAME.DAT and tomb.EXE) for this to take effect.
Installing Tomb Raider: Unfinished Business
  • Go to the folder "C:\tombraider" on your computer.
  • Select and copy the file tombub.exe and the folder named DATA.
  • Now go into the TOMBRAID folder located in your Steam Tomb Raider installation. By default this should be located somewhere similar to: "C:\Program Files\Steam\steamapps\common\Tomb Raider (I)\TOMBRAID\".
  • Paste both the tombub.exe file and the DATA folder here.
  • Go up a folder level back to the Steam Tomb Raider folder and find the file named dosboxTR.conf.
  • Create a duplicate of the file by copying and pasting to the same location. Rename this new file to dosboxTRUB.conf. You should now have the original file called dosboxTR.conf and a new file called dosboxTRUB.conf.
  • Edit the new file dosboxTRUB.conf with a text editor and scroll to the very bottom of the file. Look for a line that says tomb.exe. Edit this line so that it now says tombub.exe. Save and close the file.
  • Open Steam and in the bottom left corner click ADD A GAME... and then Add a Non-Steam Game.... Click the browse button and navigate to the Steam Tomb Raider folder.
  • Click dosbox.exe and then the open button, then the ADD SELECTED PROGRAMS button.
  • Go to you Steam Library and find the game in the list that is currently named dosbox. Right-click it and select Properties.
  • If you want to replace the dosbox icon with a different icon, here is an example icon you could use: Download this image to your computer and click the CHOOSE ICON... button. Then browse to where you downloaded the icon, select ".png" from the file type dropdown box and select the icon to apply it.
  • Back on the properties box, in the first entry box replace the word dosbox with Tomb Raider I: Unfinished Business.
  • In the second entry box leave the text but go to the end of the line. Now type in the following text after the existing text:
    -conf dosboxTRUB.conf
  • The screenshot below shows exactly where to place this text. After doing this click the close button.
Example screenshot of where to put the text.

Tomb Raider: Unfinished Business is now ready to launch from within Steam. You can run either Tomb Raider or the expansion pack from your game list and either should work correctly.

If you use Grid View or Big Picture Mode to view your Steam games list, you may also want a Steam Grid Image to use for Unfinished Business. Here is an example one:

Save this image to your computer and find Tomb Raider: Unfinished Business in your list of Steam games while in Grid View. Right click and select "Set Custom Image...". Browse to where you saved the image and apply it.
Cleaning up unused files
Now both the music files and expansion pack have been installed, it is best to clean up and remove the unused files that have been created along the way.
  • In your Steam Tomb Raider folder, you can delete all the .mp3 files and GAME.GOG as these files are no longer used. This recovers approximately 280mb of space.
  • Go to "C:\tombraider" and run the file called unins000.exe. This will only remove the temporary Tomb Raider installation, NOT your Steam Tomb Raider installation. This will recover approximately 630mb of space.

Congratulations! You have now restored the Playstation music to the original game and added the Tomb Raider: Unfinished Business expansion pack shortcut to your Steam list of games!

Thanks to the people who created all the fixes contained in the download. Thanks to the people at Tomb Raider Hub for hosting the files used in this guide. Thanks to the people at the GOG Tomb Raider forum for their help.

If you also want to improve the graphics of Tomb Raider, including changing your resolution and other fixes, then you can also use this additional guide:

The Unfinished Business expansion is essentially a separate four-level game, so you can only play those levels by launching the Unfinished Business shortcut. Your inventory (weapons/ammo etc) is seperate from the main Tomb Raider I game.

Does Unfinished Business add new levels to original game or I can play ONLY new levels launching through Unfinished Business shortcut?

The download link on Tombraiderhub isn't working today

Looks like a lot of people have picked up Tomb Raider 1 from the recent sale, I'm glad a lot of people are having success with the guide.

Thanks for your feedback GroundHound I've updated the image and some of the information.

Hat-tip to you, sir! The guide worked as advertised, and now I have the full Tomb Raider I experience! It's a shame that the game doesn't come direct from Steam with all these tweaks, but your guide is easy to follow and has pictures that clarify things.

One note, the Tomb Raider 1 & Unfinished Business Installer from Tomb Raider Hub has been updated to 1.7.2, and the install checkboxes seem to have changed a bit from your photo. Everything works fine for me, though!

this was incredible, I couldn't believe it worked! I'm the kind of person who usually tries this kind of thing once in a blue moon cuz i always screw it up, but this actually worked for me. feels good, feels really good.

Thanks man, this worked perfectly, shame there is no native widescreen support though.

At first when I followed this guide my game stopped working as well, but then I found out it was because I skipped a step in the guide (specifically renaming tomb3dfx.EXE to tomb.EXE). So make sure you read each step carefully.
