These instructions are for those who have bought Tombraider from GOG but find that the default "Tomb Raider (GOG)" settings don't work because of some oddity in their set up.

Here's what you need to do. If you run into any problems try the support page.

Download and install Glidos

Go to the download page and click the link to the latest Glidos_vXX.exe file, save it to disc and double-click it to start the install process.  The installer will put a shortcut on your desktop, unless you tell it not to. 

Configure Glidos

When using the GOG version of Tombraider, you need to tell Glidos two things: where the CD image is and where the program is. Both settings are made from the "Adjust" button.

To set the CD image path, click the "CD Source" tab, select "ISO" under "Drive or ISO" and browse for the file.

The file will be in "C:\Program Files (x86)\GOG.com\Tomb Raider 1 2 3\Tomb Raider 1\"

and will be called "GAME.GOG"

To set the program path, click the "Executable" tab and browse for the file

The file will be in "C:\Program Files (x86)\GOG.com\Tomb Raider 1 2 3\TombRaider 1\TOMBRAIDER\"

and will be called "tomb.exe"

Run Glidos and play Tombraider

We're there!  Just double-click the Glidos shortcut on your Desktop, select Tomb Raider and click the "Start game" button.  You can use the "Adjust" button to select full-screen mode and change the resolution.

Install high resolution textures, enhanced audio and enhanced movies

Glidos provides three enhencements to Tombraider.  There's an audio pack that is useful in two ways.  It provides the background music that is missing on some versions of the Tombraider CD, and it adds extra effect sounds at key points in the game to match the Playstation version.  To use the audio pack, download it from here, install it and use Glidos's "Adjust" button to set the Redbook setting under "Audio & Movies" to "Use Audio pack".

Similarly there is a FMV pack, which provide higher quality Movies. To use the FMV pack, download it from here, install it and use Glidos's "Adjust" button to select "Use FMV pack" under "Audio & Movies".

There are also texture packs available from the Tombraider Xtra site.  These vastly improve the look of the game.  There are various versions, created by different authors. To use a texture pack, just download it, install it and use Glidos's "Adjust" button to select it (Make sure you don't have "Use old-style texture pack" checked.

Buy Glidos to get rid of the spinning logo

You shouldn't run into any problems with Glidos when playing the first two levels of Tombraider, but as you start the third an annoying, spinning logo will appear.  The hope is that you like Glidos enough that you would like to contribute $10 to its further development, and that the spinning logo is sufficiently annoying to make you get around to doing so.  For details of how to get rid of the logo, take a look at the purchasing page.
