Initial D Arcade Stage 3 Recompilation

About

An experimental static ahead-of-time recompilation of the NAOMI 2 release of Initial D Arcade Stage 3 (GDS-0033) for modern Windows PCs. It translates the original SH-4 program to native code, uses a Vulkan renderer, and does not use an SH-4 interpreter or JIT fallback or a NAOMI 2 BIOS. The README marks this version as obsolete and points to a Discord for a newer one.

How it differs from the original

It is not a Dreamcast port. It adds Vulkan rendering with an authentic 60 Hz mode and experimental 90/120 Hz presentation, plus settings for resolution, widescreen, antialiasing and texture filtering. It also supports optional replacement race music and keyboard, Xbox/XInput and DirectInput wheel controls.

Getting started

Download and extract the v2489 Windows x64 ZIP, put your own matching gds-0033.chd and 317-0384-com.pic files in the included game files folder, and run the launcher executable. The launcher checks the inputs and extracts the required files; about 1.3 GB of temporary space is needed on first run. The README advises starting with the default 60 FPS mode.

Known issues & limitations

• This is unfinished playtest software, not a finished port; visual, audio, timing, transition, controller, card, and course-specific defects may remain.
• Higher-refresh presentation is experimental and may cause jitter, clipping, flicker, or unstable performance on unverified content and hardware.
• Unlimited presentation rate is not finished.
• Every car, opponent, long campaign/result/persistence permutation, and error branch has not been exhaustively completed on one integration executable.
• Live controller and wheel behavior, force feedback, and audible end-user audio still need broader acceptance.
• Shutdown stress testing across more GPUs and drivers is still required after earlier host black-screen incidents; close the game normally.
• Clean-machine packaging needs broader community testing.

What you need to run it

Features

• The game renders through Vulkan and offers output-resolution, widescreen, antialiasing, texture-filtering, fullscreen, and V-sync settings.
• The F1 menu has Video, Controls, HUD, Card, and Music pages.
• Keyboard, Xbox/XInput, and DirectInput wheels are supported, with persistent remapping.
• Supported DirectInput wheels have adjustable force-feedback strength.
• Steering smoothing can be adjusted from 0% to 100%; 0% keeps the original unfiltered response, and the setting is saved.
• Optional race-music replacement supports MP3, WAV, and FLAC; clearing a replacement restores the original track.
• You can create and select cards in the visible card data folder; the last selected card loads on the next start.
• The launcher checks for releases and can optionally install verified updates while preserving user data.

How to install

1. Place your matching CHD and security PIC in the included `game files` folder.
2. Run `Initial D Arcade Stage 3 Recompiled.exe`.
3. Start with the default 60 FPS mode.

Controls

• In the F1 Controls page, use the D-pad or left stick to navigate and A or B for actions.
• Xbox triggers act as independent accelerator and brake axes.
• Pressing F1 in game opens a menu with Video, Controls, HUD, Card and Music pages.

Status & roadmap

• The README calls it a public early demo and not a finished port; visual, audio, timing, controller, card and course-specific defects may remain.
