The classic 1990 Stunts, also known as 4D Sports Driving, has received a new experimental version that runs directly in the browser. The project allows the game to run with high-definition graphics, widescreen support, and animations adapted for 60, 120, and 144 Hz monitors.

The developer showcased the demonstration on October 10, 2026, in a post on the r/decomps community. In addition, they made available a page where players can upload the files from their own copy of the original title.

Stunts from 1990 runs in the browser with modern graphics

The proposal is to preserve the behavior of the classic racing game while modernizing its presentation. Thus, the new renderer draws tracks and vehicles at screen resolution, rather than simply upscaling the original 320 × 200 pixel image. Another project that adapts a classic to browsers is 2003's Crimsonland, although it follows a different technical path.

According to the creator, the experimental version also removes the traditional render distance limit. In addition, it adds polygonal shadows for cars, buildings, bridges, and obstacles.

The environments also gain water with reflections and ripples, skid marks, and three-dimensional crash effects. However, these improvements do not necessarily alter the original racing physics.

In addition, the player can switch between the modern appearance and the original visual during a race. According to the developer, simply press the H key to compare the two presentations.

How does 1990's Stunts work without installing a traditional emulator?

Despite running in the browser, the project is not a conventional native port. Instead, the page uses a technique that dynamically translates the original DOS executable into JavaScript.

Then, this code runs on top of a layer that recreates components of the old PC, including VGA video, keyboard, timer, and AdLib audio. Meanwhile, a modern renderer redraws the game's three-dimensional objects.

Thus, the project preserves the logic of the original title, including handling, collisions, opponents, and replays. However, there is a partial recreation of old hardware. Therefore, it would be incorrect to claim that the version completely dispenses with any emulation technology.

1990's Stunts runs smoother on monitors up to 144 Hz

Another new feature involves fluidity. According to the creator, the browser interpolates movement between the frames produced by Stunts' original logic.

As a result, the visual presentation can support 60, 120, or 144 Hz monitors without artificially speeding up the race. This way, the game maintains its physics timing while the renderer presents intermediate movements.

The developer also implemented widescreen support during races, including in the cockpit view. On the other hand, the menus continue to respect the classic 4:3 aspect ratio.

However, there is not yet an independent performance measurement confirming 144 frames per second on different computers. These features represent the capabilities reported by the author.

Stunts from 1990 adds best lap ghost and shared tracks

In addition to graphic improvements, the project adds features that were not part of the original version. One of them is the best lap ghost, which allows racing against your own previous time.

Another function allows sharing tracks using short codes. Thus, players can exchange custom circuits without having to manually send all game files.

The browser also accepts track files in TRK format. In addition, the developer created a three-dimensional layout preview, which the user can rotate and zoom in on before starting the race.

How to play 1990's Stunts in the browser?

The project maintains a experimental public demonstration. However, the page does not offer a commercial copy of Stunts.

Therefore, the player needs to provide the files of their own version 1.1. According to the developer, the browser reads the ZIP file locally, without uploading the game to the server.

1. Access the official demo via the button below.
2. Prepare a ZIP file of your own copy of Stunts 1.1 for DOS.
3. Upload the ZIP to the page's interface.
4. Wait for the browser to prepare the game execution.
5. Start a race and check the available graphic options.
6. During the match, press H to compare the original visuals with the modern renderer.

The button opens the creator's web application. It does not provide the commercial game files or install an executable on your computer.

What has changed compared to the original Stunts?

Released in 1990 by Distinctive Software and published by Brøderbund, Stunts stood out for its track editor and obstacles that allowed players to perform jumps, banked turns, and loops.

The game also offered different cars, computer-controlled opponents, and a replay system. In addition, players could create their own circuits and try to set better times.

Now, the experimental reconstruction adds higher-resolution graphics, greater visual fluidity, and tools for sharing tracks. However, it preserves the stunt and racing concept of the old game.

Offline version is still in development

In the presentation's comments, the creator stated that he is also working on an executable version outside the browser. On October 11, he mentioned this development again.

However, this does not yet confirm the release of packages for Windows, Linux, or Android. Therefore, the web demo remains the public option identified in this investigation.

The project should also not be confused with a full static recompilation. In that case, the browser dynamically translates the DOS executable and uses its own layer to reproduce components of the original hardware.

Finally, it is worth remembering that video and performance features still depend on independent testing. Interested players can follow the creator's publication and report issues directly to the community.
