🚀 Deploy to GitHub Pages

1. Fork or create a new repository on GitHub (e.g. yourusername/webemu)

2. Upload these files to the root of the repository:

   • index.html
   • README.md

3. Enable GitHub Pages:

   • Go to your repo → Settings → Pages
   • Under Source, select Deploy from a branch
   • Choose main (or master) and / (root)
   • Click Save

4. Your site will be live at:

   https://yourusername.github.io/webemu/
   

   (GitHub may take 1–2 minutes to deploy on first push.)

📡 CDN Sources

The emulator loads game engine data from external CDNs. On first load, it automatically pings all available sources and selects the fastest one:

CDN	Notes
EmulatorJS — Stable	Recommended, most reliable
EmulatorJS — Latest	Bleeding edge builds
unpkg (npm registry)	npm mirror
Statically (GitHub CDN)	GitHub raw mirror
GitHack	GitHub raw fallback

Note: The "Local / Self-Hosted" CDN option requires EmulatorJS data files hosted alongside the site (in a data/ folder). This won't work on GitHub Pages unless you add those files to your repo — use one of the remote CDNs instead.

🕹️ Controls
