Sound-effects port

The original HTML5 repository does not contain audio files, so the 32X edition now includes original effects synthesized specifically for this port:

menu cursor, confirmation, and back sounds;
a continuous procedural racing-engine loop with rising pitch;
stereo-panned left/right lane-change whooshes;
stereo-panned traffic pass-by effects;
pause and resume cues;
a long stereo-panned collision/explosion effect.

The Slave SH-2 is dedicated to audio. It mixes the engine and one priority-based PCM voice in real time, feeds the 32X's three-word PWM FIFOs at 22,050 Hz, and converts signed 8-bit samples into the safe PWM range. The Master SH-2 sends nonblocking commands through COMM4; COMM6 carries the audio-ready handshake. Playback uses separate left/right PWM registers for stereo panning.

WAV previews of each generated effect are under assets/sfx-preview/. They are development previews and are not embedded as WAV containers in the ROM.
Implementation notes

320×224, 8-bit double-buffered 32X VDP output.
Shared 256-color RGB555 palette and ROM-resident indexed art.
Native 30 Hz game loop, matching the browser game's update rate.
Master SH-2: game logic and rendering.
Slave SH-2: continuous 22.05 kHz stereo PWM mixer.
68000: controller polling and VBlank counter.
No external runtime data is required.
