About

OpenGTPS1 is an experimental static-recompilation port of the US Gran Turismo 2 Simulation Disc (SCUS-94488, revision 2) and Arcade Disc (SCUS-94455), built with RecompOne. Version 0.9b targets Windows x64 and is playable, with races, championships and replays working, but it is not a finished 1.0 release. The player must supply their own matching discs; the repository contains no game data.

How it differs from the original

It uses a modern 3D renderer with 4x source rendering, extended draw distance, maximum vehicle detail and horizontal-plus widescreen. Menus, videos and HUD still use the game's own 2D screen-command compositor. An optional installer step can merge content from a US Gran Turismo disc, such as Special Stage Route 11 and extra cars, into the GT2 modes.

Getting started

Download the 0.9b Windows ZIP, extract it to a writable folder and run GranTurismo2PC.exe. The first-run setup finds your own disc images (ripped as raw Mode 2/2352 .img files), validates them, and installs locally; no PlayStation BIOS is needed. Xbox-compatible controllers are supported, and the README lists default keyboard bindings. OGG music files can be placed in a music folder.

Known issues & limitations

The planned original Xbox port has not been implemented.
Some cars in the generated development smoke-test save have incorrect wheel widths.
At least the black JGTC Castrol Supra can turn white when a race begins.
Known defects include incorrect wheel widths on some cars in a development test save, and a black JGTC Castrol Supra that can revert to white when a race begins.

What you need to run it

Original game files required. The project ships code only; you provide your own copy of the game (PlayStation version).

You need your own supported US Gran Turismo 2 Simulation Disc, revision 2, and Arcade Disc.
Other disc regions and revisions are not supported.

Features

One title menu launches Arcade Mode, Gran Turismo Mode, Replay Theater, and options.
Complete races, championships, results, and native replays are playable.
Xbox-compatible controllers are supported.
Memory-card saves persist, and valid Simulation saves load before the unified title.

How to install

Rip both matching GT2 discs as raw Mode 2/2352 .img files.
Run GranTurismo2PC.exe, use Browse if setup does not find the disc images, choose whether to merge GT1 content, then select Install and play.
