Engines roar, tyres screech. Pulses pound as the drivers push their cars to the limit, all to be the first past the chequered flag.

Eight different race tracks all with stunning backdrops, eight frenzied competitors with you on the track, and at the end of the day, just one winner. Can you meet the GTS Racing Challenge?

And its 3, 2, 1... GO!!!!! GTS Racing Challenge gives you the adrenaline charged, motor sport experience that you been waiting for in a Palm OS game!

GTS Racing Challenge Turbo Edition features:

How To Install

Use an extractor program such as WinZip or Stuffit Expander to get at the GTS Racing Challenge files. Install the game by double-clicking the .prc file, which opens the Palm Install Tool program.

Use the HotSync button as usual to install the game onto your handheld. If you have a handheld with an expansion card, you can then move the game over to it. Do this before you register the game!

Now run GTS Racing Challenge and tap the screen to play the game!

If you've got any queries about GTS Racing Challenge or the registration process, first check out our knowledge base on our website (you must be connected to the internet to access this). If this doesn't help, get in touch with us at [email protected]. If you've got any questions (or suggestions, we love those) about the game itself, please get in touch with us at the email address at the top of this page.

Quick Start!

Follow these instructions to get into the game and get driving!:

Car Controls, or "Driving 101"

GTS Racing Challenge has two car control methods, Buttons (uses the buttons on the bottom of your Palm) and Graffiti (uses the stylus in the Graffiti area).
On installation, the game defaults to the "Button" system. If you want to change to use the Graffiti system instead, use the Car Controls menu (Options->Settings->Car Controls). You can also change in game, simply pause the game by tapping on the screen or the menu button and choose the Options menu

By default, GTS Racing Challenge will have a set of button controls pre-defined that will be comfortable on the majority of devices. However, if you wish to change the button controls, you have complete freedom to do so. From the Options Menu, select "Controls", and you can assign a different set of buttons to steering, acceleration and changing gears.

Each car can be driven with either an automatic or a manual transmission, selectable from the "Transmission" menu (Options->Settings->Transmission). There are three options here, "Automatic", "Manual" and the default, "Auto + Revs", "Auto + Revs" gives an automatic transmission but still displays the rev counter and currently selected gear.

Hints and Tips

Controls Revisited

If you get stuck against the edge of the track, you may find it helpful to use reverse gear. How you engage reverse gear depends on the control method and the transmission type:

The game camera and car are free to rotate, as this picture would show, if you were currently connected to the internet.
The camera and car are both free to rotate through 360 degrees: together with the photo-realistic track and horizon textures, this give GTS Racing Challenge even more freedom and realism.

Sound effects

Game sound can be adjusted from the sound options menu (Options->Settings->Sound Volume). The default setting is "100%", and you can change this by tapping on the bar or on the "+" and "-" icons either side of the bar. Tapping "Cancel" will return you to the Settings menu without saving your changes, and tapping on "Enter" accepts and stores the change.
Tapping on "Off" or "Max" sets the volume level to 0% or 100% respectively, allowing quick setting of the most common volume choices.

Technical Info - for the Curious!

Technical details

Palms don't have the kind of specialised display hardware that modern console or PC racing games like Mario Kart rely on, so GTS Racing Challenge has to use the CPU to create all elements of the display. This is a very tall order for the Palm's Dragonball processor, and required radical coding methods to get game-quality performance. The heart of the software renderer, the DDA (Differential Digital Analyzer) module, was built from over 30,000 lines of assembly language, mechanically generated by a special-purpose compiler.

The result is a game engine that can display a high-definition texture-mapped track with scaled car and tree sprites, scrolling background and onscreen instruments, at 18-20 frames per second on a Palm m130.


If you downloaded the game straight from the internet, from Astraware's web pages, or from one of the popular handheld download sites, then your copy is in 'Demo' form. Demo means that you can play free for a while, and then decide whether to register it or not.

In Demo form, you can play GTS Racing Challenge for free, as you decide whether you like it or not. After each time you play, the program will display a short message asking you to register or purchase a full version!

Registering Online:

For those that like the speed and convenience of buying of the internet, when you register for the game, you'll get a key which will unlock the game and remain valid for future upgrades. Go to the web page at for more details.

You'll need to know your HotSync ID which you can find by running GTS Racing Challenge, and selecting "Register" from the "Options" menu item. Your HotSync ID (or username) will be filled in for you. You can also find it by tapping on the "HotSync" icon of your Palm, and looking in the top right hand corner of the screen.

When you register, Astraware will generate a key based on your ID, which will normally be sent out by email within 48 hours of you registering. When you receive your key, go to the same register option, and enter the key into the space provided.
