emulatorjs

A javascript emulator for nes, snes, and more! The BEST emulator on the internet. No ads and self hosted!

Example page: https://coldcast.org/games/1/Super-Mario-Bros

demo: https://ethanaobrien.github.io/emulatorjs/

Where did I get this?

So I found this website called emulatorjs and I went into inspect and downloaded the resources. I removed the ad server, and made everything work within your own domain. https://github.com/linuxserver/emulatorjs may soon make it possible to use all this open source

The emulator is not illegal - the rom is - I am not responsible for what people decide to do with this software.

NOTE: The screen recording option does not currently support audio! only video recording is supported at this time.

How To

  1. Download this repository (Code > Download as zip) then Extract the contents
  2. Load into a web server and open localhost

If you have questions, ask me and I will clarify (use the issues tab). Please search to make sure your isuue hasnt already been asked

IF SOMETHING DOES NOT WORK - Please make an issue!! Include as many details as possible and please include a log of the console!

All roms can be zipped into a .zip, .rar, or .7z archive
