MameCloudRom v1.0 is released. MameCloudRom (MCR) is a Windows virtual file system (using WinFsp) designed for MAME ROM management. It implements a Lazy Download mechanism: when MAME requests a ROM that doesn't exist locally, MCR automatically downloads it from a configured remote server and serves it seamlessly.

MameCloudRom Changelog:
This is the landmark Production Release of MCR, bringing ultimate flexibility and extreme stability to the user.
🛠 Major New Features
Custom Path Prefixes: Full control over remote directory structures. Users can now define custom folder prefixes for .zip (-zp) and .7z (-7p) files (e.g., split/, standalone/, or any site-specific path).
Generic Routing Engine: Replaced hardcoded structures with a dynamic, prefix-aware routing engine that supports any archival layout.
Extreme Stability (v0.2 Architecture): Adopting the highly-reliable handle protection and permission logic from v0.2, ensuring 100% stability even with WinFsp 2025 and Windows File Explorer.
Multi-Language Support: Fully localized setup and configuration tools supporting English, Traditional Chinese (TW), and Simplified Chinese (CN).
⚙ Technical Improvements
Detailed Downloader: Visual real-time progress bars via curl and precise file size (MB/KB) display.
Warning-Free Build: Fully optimized C++ codebase with strict type safety and zero compiler warnings.
Dynamic Driver Alignment: setup.bat automatically synchronizes the correct winfsp-x64.dll from your local WinFsp installation, ensuring perfect version compatibility.
Audit Skip Optimization: MCR intelligently distinguishes between MAME "auditing" and "launching," ensuring that ROM scans don't trigger unnecessary downloads.
📚 Documentation & UX
Interactive Setup: setup.bat handles environment checks, WinFsp detection, and language selection in one go.
