The game

The original game. A new, native engine.

Stunt GP is a radio-controlled car racer on tracks full of ramps, jumps and steeply banked corners. StuntGP NEW rebuilds the whole path through the game: language selection, title screen, menus, name entry, choice of mode, vehicle and track, the race, the results and the return to the menu — all in one consistent game world.

It is neither an emulator nor a wrapper around the old EXE file. Driving mechanics, track contact, rival AI and the camera are new native code rebuilt from the instructions of the original program. The game uses the original data: models, textures, fonts, music and effects.

Where the original behaviour has not been rebuilt yet, the game reports an explicit error naming the function — instead of substituting an invented “toy” driving model.

Single Player

Quick Race Action.

Modes from the original game menu. Labels and help texts come straight from the game files.

Features

Faithful to the original, comfortable on a modern PC

  • Original menus

    Language selection, title screen, main menu, name entry, vehicle selection and track preview run on the game's original graphics, fonts and texts.

  • One seamless game

    Menu → track and mode → race → results → menu. Everything happens in one game world, with no separate preview mode.

  • 60 steps per second

    The simulation runs at the original pace: 60 steps per second, regardless of the monitor's refresh rate. A game step including rendering takes about 3–5 ms.

  • Any monitor

    The picture fills the window at native resolution, with no bars and no stretching. Races use Hor+ — a wider view to the sides with the original vertical field of view. The HUD sticks to the screen edges.

  • 120, 144, 240 Hz

    Frame interpolation shows smooth motion up to your monitor's refresh rate, with pacing locked to the display. The game itself keeps 60 steps per second, so no key presses get lost and music and loading screens keep the original pace.

  • Original assets

    Vehicle and track models, textures, fonts, music and sound effects all come from the original game files.

  • Rebuilt, not invented

    Every rebuilt behaviour must point to specific instructions in the pinned original EXE file. Decompiler pseudocode alone is not accepted as proof.

  • Original bugs fixed

    11 documented fixes, described separately from the recovered behaviour — for example a half-second pause every 7 minutes or so, caused by a 32-bit clock counter overflowing.

Gallery

Real screenshots from the game

Every image is a screenshot of version R1, taken from a gameplay recording of 30 Sep 2026 — no retouching, no mock-ups. The game runs in widescreen: races, menus and results fill the whole 16:9 picture.

    Launch

    Double-click START.cmd. If a SmartScreen warning appears, choose “More info” → “Run anyway”.

  4. GO

    Play!

    On first launch, pick the menu language. On the title screen press ENTER, choose SINGLE PLAYER, a mode and a vehicle — and hit the track.

Controls

Keys and launch options

On the track

  • ↑Accelerate
  • ↓Brake
  • ←→Steer
  • ESCPause during a race

In menus

  • ↑↓←→Select an option
  • ENTERConfirm
  • A–ZEnter the player name

The default keyboard layout comes from the original game data. SPACE, SHIFT and CTRL handle the original layout's extra actions.

Launch options StuntGP_NEW.exe

OptionEffect
--interpolationTurns frame interpolation on for this session (--no-interpolation turns it off). Normally you set it in Options → GRAPHICS → INTERPOLATE.
--aspect-4x3Original 4:3 picture with bars, like ASPECT → ORIGINAL in the graphics options. The SGN_ASPECT=4x3 environment variable does the same.
--width 1280 --height 720Window size (1440×900 by default).
SGN_GPU_WORLD=1Environment variable: track geometry computed on the GPU. Optional, off by default.

Most settings no longer need launch options: display mode (window, borderless or exclusive fullscreen), interpolation, VSync, frame limit, anti-aliasing, texture filtering and more are in Options → GRAPHICS, and during a race under ADVANCED in the pause menu.

StuntGP_NEW.exe --interpolation --aspect-4x3

Project status

An honest look at what's ready

Working in R1

  • The complete single-player game: Arcade, Exhibition, Time Trial, Stunt Challenge and Championship
  • Language selection, title screen, menus, name entry, vehicle and track selection
  • Races against five AI rivals: start, laps, stunts and bonuses, finish, results, rankings and unlocks
  • Music and all sound effects, HUD, camera, pause menu, particles, trails and shadows
  • Widescreen, graphics options, display modes and frame interpolation up to the monitor's refresh rate

In progress

  • Multiplayer is not in R1 — it will be designed from scratch as a separate, networked mode
  • Full visual and game-state parity with the original has not been proven yet
  • The R1 build was checked with the author's visual tests and measurements; automated tests and comparisons with the original were not run for it

Release

  1. R1 30 Sep 2026

    The first public version

    R1 is the first public release of StuntGP NEW. It contains:

    • The complete single-player game — all five modes, from Arcade to Championship
    • Music and all sound effects
    • Widescreen: the picture fills any window, with Hor+ in races
    • Frame interpolation up to the monitor's refresh rate, with display-locked pacing
    • Graphics options and display modes: window, borderless and exclusive fullscreen
    • The crash on exit is fixed, and the menus no longer stutter

How it's made

  • From instructions, not guesswork

    Rebuilt behaviour must point to the pinned EXE file (SHA-256), the decompiled function and the exact instruction ranges. The decompilation is not the original source code.

  • Comparisons with the original

    Oracles run the original's unmodified instructions in the Unicorn emulator and compare the results with the new code — for example the pause and resume routines: 13,280 compared calls with no differences.

  • Strict builds

    C++23, compiled with /W4 /WX — warnings treated as errors — and /fp:strict for strict floating-point arithmetic.

  • New platform, clearly labelled

    The window, the DirectX 12 renderer, picture scaling and presentation pacing are new code — labelled as new, not as recovered game behaviour.

FAQ

Frequently asked questions

Is this the official game?

No. StuntGP NEW is an unofficial fan project, not affiliated with Team17 Software Ltd. Stunt GP and Team17 are registered trademarks of Team17 Software Limited.

Is it an emulator or a wrapper around the original EXE?

No. It is a native x64 program written from scratch in C++23, with a DirectX 12 renderer. The original executable is not run — it serves as the reference from which the game's modules are rebuilt.

Is the game finished?

The single-player game is complete in R1: all five modes, music and sound effects, results, rankings and unlocks. Multiplayer is not included yet — it will be designed from scratch as a separate, networked mode. Full parity with the original has not been proven yet.

Windows shows a warning when I launch it

StuntGP_NEW.exe is not digitally signed, so the SmartScreen filter may block it. Choose “More info” → “Run anyway”. To be safe, compare the SHA-256 checksum of the downloaded file with the value in the Download section.

MSVCP140.dll or VCRUNTIME140_1.dll is missing

Install the Microsoft Visual C++ Redistributable 2015–2022 (x64) from Microsoft: aka.ms/vs/17/release/vc_redist.x64.exe.

Does it work on a 144 Hz or 240 Hz monitor?

Yes. The game runs 60 steps per second regardless of the monitor's refresh rate, and frame interpolation (Options → GRAPHICS → INTERPOLATE) shows smooth motion up to the screen's refresh rate, with pacing locked to the display.

I have an ultrawide monitor

The picture fills the whole window with no bars, and races show a wider view to the sides (Hor+). If you prefer the original 4:3 framing, set ASPECT to ORIGINAL in the graphics options or launch the game with the --aspect-4x3 option.

Which languages does the game menu offer?

On first launch the game lets you choose one of the seven languages stored in the original data: English, Dutch, German, Swedish, Italian, Spanish or French. There is no Polish version of the game menu — Polish is available only on this website.

Where does the game save its settings?

In the save\card00 folder next to StuntGP_NEW.exe. That is why you should unpack the game somewhere you can write to — for example the Desktop, not Program Files.

Version R1 is waiting at the finish line

Download, unpack, run START.cmd — and race the original Stunt GP tracks.
