📁 Mirror 1: Drive (fast) 📁 Mirror 2: Archive.org (backup)

| Feature | Description | |---------|-------------| | No “Request Access” screen | Use service account or public link with anyone with link can view + backend tokenization. | | Download quota avoidance | Each user gets a fresh signed URL; Google enforces per-user, per-file limits (approx. 750MB/day per file for anonymous). Workaround: Use multiple service accounts or mirror files. | | Metadata caching | Store file name, size, MD5, modified time in database. Update weekly via Drive API. | | Download manager support | Return Content-Disposition: attachment; filename="game.7z" and Accept-Ranges: bytes if proxying. | | Virus scanning | Before generating URL, check if Google Drive has flagged the file as infected (Drive API returns trashed or virus properties). | 5. Limitations & Solutions | Limitation | Solution | |------------|----------| | Google Drive daily download quota (10–20GB per file for public links) | Use multiple mirrors (Drive, OneDrive, Dropbox) or a load balancer with several service accounts. | | No native resume support | Proxy downloads through your server with Range header support (requires storing partial data). | | Download speed throttling | Use Google’s CDN – usually fast, but you can add a CloudFlare Worker in front to cache. | | Legal risk (DMCA for copyrighted ROMs) | Only use for homebrew, open-source firmware, or legally owned backups. Add disclaimers. | 6. User Interface Mock Description On the ROM details page:
