Overview

Bug FixesRestored ContentRebindable Controls

IMSA World Championship Racing Recomp is a static recompilation of IMSA World Championship Racing, the sports prototype racer Studio 3DO made for the Panasonic M2 before the console was cancelled, together with shooter2d, a small game on the same disc. It runs both as native programs on Windows, macOS and Linux. It aims to be as faithful to the original as possible while stopping short of being an emulator, and no part of the game is included: the launcher copies what it needs from the player’s own disc image.

The original’s controls were famously poor and its in-game control options never worked. The port can use the original control profile, a patched one that makes the game’s settings work, or a custom one, and offers a rewritten analog control scheme that uses live physics calculations. Bug fixes, enhancements and unfinished features restored from the disc can each be turned on or off.

The launcher handles setup, graphics and control settings, the fixes and enhancements, and save data, can start either game directly, and includes a 3D viewer for the cars.

How to Set It Up

  1. Download the zip for Windows, the .dmg for macOS or the AppImage for Linux. Extract the zip, or move the app to Applications.
  2. Start the launcher. On the first run it asks for your IMSA disc image and copies the files it needs from it.
  3. Set up graphics, controls, bug fixes and enhancements in the launcher, then start IMSA Racing or shooter2d.
  4. To update, replace the program. Your saves, settings and the files from your disc are kept apart from it (with the Windows zip, copy the old userdata folder into the new one).

What's new in v1.0.1

Fixes

  • The game no longer receives the host program’s own command-line options. On macOS this started every session with the game’s developer -u option, which runs the car physics on the main processor instead of the emulated second processor and turns on a debug path recorder. On Linux, extracting the .tar.gz under folders such as /tmp or /var could turn on other developer options. Windows was not affected.
  • Packaging fixes for the Linux AppImage and Windows package names.
