Architecture

rh-mgr is a hybrid application built with:

• Frontend: React + TypeScript (bootstrapped with Vite).
• Backend / Host: Tauri (Rust).
• Database: SQLite (local storage for library metadata).

Core Components

Frontend (/src)

• React Components: The UI is built with functional components and hooks.
• Tailwind CSS: Used for styling.
• Radix UI: Provides accessible UI primitives (dialogs, tooltips, etc.).

Backend (/src-tauri)

• Tauri Commands: Functions exposed from Rust to the frontend (e.g., patch_rom, launch_emulator).
• Patching Logic: Rust implementation of IPS/BPS/UPS patching (using existing crates or custom logic).
• Database: rusqlite handles interactions with the local SQLite DB.

Data Flow

1. User Action: User clicks "Patch" in UI.
2. IPC: Frontend invokes a Tauri command (invoke('patch_hack', ...)).
3. Rust Backend:
   • Downloads file.
   • Reads clean ROM.
   • Applies patch.
   • Writes new file.
   • Updates SQLite database.
4. Response: Backend returns success/failure to UI.
