About

Gran Turismo 2 PC, VR & Browser is a native C++ port with Arcade and Simulation modes, cockpit driving, and desktop and VR support. The same game code is compiled to WebAssembly for browser play with WebGL2. Project code is under the MIT License.

Getting started

Supply your own supported disc images; game data, BIOS and saves are not included. Extract the release into a writable folder and run the installer for your platform (Windows, PCVR, Quest, macOS or Steam Deck). In the browser version, serve the web folder over HTTP(S) and select your BIN image.

Known issues & limitations

Only one disc is available per browser page session; reload after graphics-context loss.
Cross-platform multiplayer and PSVR2 Sense adaptive triggers are planned for a future release.
The original 100-car garage limit remains.
Compiling arbitrary new-track geometry is not implemented.
Changing VR resolution requires restarting; other supported VR graphics settings apply immediately.

What you need to run it

Original game files required. The project ships code only; you provide your own copy of the game (Windows, macOS, Linux, VR, Other version).

You must provide your own supported disc image; game data, BIOS, and saves are not included.
Use complete 2352-byte-sector BIN/CUE images; the browser accepts a single full BIN directly.
Browser play requires WebGL2, an 8192-pixel texture limit, and at least 512 array texture layers.
A BIOS is optional and is not required for normal play.

Features

Drive in a fitted cockpit in single-player Driver view, with seat adjustments and a rear-view mirror.
PC and Quest support VR driving with stick, virtual-wheel, or motion steering.
Arcade cheats can unlock course selections and the car roster; Simulation VR cheats include licences, credits, events, and a car catalogue.
The browser version supports keyboard/gamepad input, audio, persistent saves, and save backup import/export.
Native installers can prepare HD menus, fonts, HUD, and movies from local game assets.

How to install

Extract the complete ZIP into a writable folder and keep its source and scripts together.
On Quest, run INSTALL-QUEST.bat and follow the Quest instructions.
On macOS, run INSTALL-MACOS.command, then open the installed GT2.app.
On Steam Deck, switch to Desktop Mode, extract the ZIP, run INSTALL-STEAMDECK.sh, and open the installed shortcut.

Controls

Menus use arrows or the D-pad to navigate, Enter to select, and Space to go back.
In the browser, Shift+Q opens settings.

Summarised from the project's README.

Status & roadmap

Cross-platform multiplayer and PSVR2 Sense adaptive triggers are planned for a future release.

Additional notes

Browser limits: Browser play holds the whole BIN in memory, allows one disc per page session, and does not support VR or physical-wheel force feedback.
