Power Dozer v0.83 — audio fixes and PC settings

PC Settings now shows every option in complete Display, Graphics, Audio and Controls sections. Controls displays all fourteen logical actions together. The overlay uses the original game font, palette and translucent shadows decoded from your own ROM, with keyboard, mouse and controller navigation, optional remapping and matching Xbox/PlayStation/Switch prompts. Tiny white arrows centered inside stick icons show the physical direction, including remapped actions.

Two bounded audio repairs address pending audio starvation during active graphics and soundplayer heartbeat loss through queue saturation or stale event state. Original guest scheduler/callback regressions cover the causal mechanisms. A ten-minute Linux GPU/PulseAudio attract run kept progressing with nonzero late PCM and no rejected output buffers; this does not establish universal audio stability or identify the initiating event of every native dropout.

Includes Linux x86-64 runtime, source archive and SHA-256 files. Windows v0.83 is pending a fresh native build and validation; Windows v0.82 remains in its earlier release. Supply your own Blast Corps USA Rev 1 ROM. No ROM, extracted game images, private generated game code, saves or recordings are included.

Validation: 55 CTest checks and 153 Python tests passed. Native Linux settings runs exercised Xbox, PlayStation and Switch virtual controllers for four minutes each and reloaded saved preferences. The centered-arrow build passed a separate two-minute visual check. The relocated portable runtime passed a 90-second Vulkan/PulseAudio attract run with nonzero late PCM and no rejected buffers. Physical hardware acceptance is separate.

This is a public testing beta. Real controller hardware, speaker/headphone output, broad mission coverage and sustained 4K/120 Hz remain manual checks. Source/license certification flags retain their existing documented status.
