Castlevania: Harmony of Dissonance Recomp v0.1.0-preview

A high-performance native PC port (static recompilation) of Castlevania: Harmony of Dissonance (Game Boy Advance) for Windows x64, featuring a native graphical launcher powered by recomp-ui.

Highlights & Features

  • Native PC Execution: Statically recompiled ARM7TDMI code running natively on x86-64 at a smooth 60 FPS.
  • Modern Graphical Launcher (recomp-ui):
    • ROM and BIOS selection with real-time SHA-1 and identity verification.
    • Video settings: Window scale (1x to 6x) and Fullscreen toggle.
    • Audio settings: Master volume slider and mute controls.
    • Controls: Configurable keyboard bindings and SDL2 game controller / gamepad mapping with live button prompts.
    • Configuration persistence (launcher_config.json) with an optional "Skip Launcher" mode for direct boot.
  • Dual Executable Support: Bundled with both the branded executable CastlevaniaHarmonyOfDissonanceRecomp.exe and backward-compatible alias hod.exe.
  • Accurate Save Emulation: Full Flash512 (64 KiB) save memory emulation with signature verification (CASTLEVANIA1.00), matching genuine GBA cartridge behavior.
  • Zero Dependencies: Standalone Windows x64 release package with all required MinGW-w64 and SDL2 runtime libraries included. No external development tools or compilers required.
