Road Rash Trilogy Recomp

Road Rash Trilogy Recomp

A native Windows x64 fan project for Road Rash, Road Rash II and Road Rash 3 from the Mega Drive / Genesis. Version 0.50 adds an English launcher, remappable controls and an installer that builds the games from your own ROMs.

Install and play

Download version 0.50 (initial public test, Windows x64):

• Standard installer
• Offline installer
• SHA-256 checksums

1. Extract the complete RoadRashTrilogyRecomp-0.50-Windows-x64.zip package.
2. Open RoadRashTrilogyRecomp.exe and choose Install games.
3. Select your ROM folder(s) and an empty installation folder.
4. Let the installer verify your files and compile the supplied games locally.
5. Open the installed launcher, choose a ready title and press Play.

You must provide compatible original dumps. BIN, MD, GEN and ZIP are accepted. Only these verified revisions are supported: Road Rash (USA/Europe), Road Rash II (USA/Europe, RR206), and Road Rash 3 (USA/Europe). Japanese ROMs, other regions or revisions, modified images and interleaved SMD dumps are not supported. Files are identified by SHA-256, not by filename; renaming an unsupported ROM will not make it compatible. See the exact hashes in games/supported-roms.json. One folder may contain all three games; only supplied games are installed. The package contains no ROMs or generated game code. No game files are downloaded. Microsoft C++ tools are required; the installer prepares them if missing, through Windows administrator consent. The offline package includes verified SDK caches but requires Microsoft C++ tools to be installed already for fully offline use.

See installation and supported revisions, controls and building from source.

Original Mega Drive vs continuous zoom (0.50)

Each GIF shows the same replay and the same captured frames side by side: original Mega Drive rendering on the left, version 0.50 continuous zoom on the right. Both views use 4:3, matching inputs and normal game speed. The original view uses the native raster renderer in this project's runtime.

Road Rash II

Road Rash 3

Captured with the published 0.50 binaries. Each pair preserves guest RAM/VRAM and the HUD. The 4-second GIFs sample the 59.94 Hz capture at 50 fps, retaining the original pixels and elapsed time. Capture details and hashes.

Features

• Classic trilogy covers, a sober dark launcher and native Windows navigation.
• Remappable keyboard/controller inputs for two original player ports, including button/axis capture, controller assignment, deadzone and 3-/6-button pad options.
• Continuous scenery and vehicle zoom, road/marking smoothing and short visual prediction in recognized single-player races, preserving original game speed.
• Wide sprite margin recovery and continuous vehicle depth across animation changes; implementation and high-curve / near-camera corrections.
• Vehicles follow the current hill profile and keep their authored proportions beside the player; vehicle depth and validation.
• Curve-relative vehicle lanes, live far-cutoff recovery and separate forward / mirror poses stabilize fast steering and braking; latest corrections.
• Continued near-camera growth and complete sprite exits during overtakes; current correction and arcade / 3DO / PS1 / Saturn references.
• Bounded rival lane correction, native attack-overlay order and safe transitions between riding and separate rider/bike poses; latest validation.
• Native vehicle anchors preserved at the starting grid and close pose changes, with depth-consistent height corrections; current follow-up.
• Optional experimental 16:9 expansion, resolution selection and CRT filters through librashader / koko-aio.
• Original sound and optional local remake music, independent volume settings, and local achievements with an in-game F6 panel.

The games execute translated 68000 code with fallback for remaining paths. Complete static coverage and full campaign validation are not claimed. Menus, pause and original split screen retain their original raster presentation. Network multiplayer is not implemented. Windows release installers include 18 Dean Harris remake tracks, installed locally with no separate music download. The original soundtrack remains selectable. See music and 0.50 scope and validation.

Source navigation, reproducible build/test commands and development history are in AGENTS.md.
