<h1>emulatorjs</h1>
|
||||
|
||||
A javascript emulator for nes, snes, and more!
|
||||
The BEST emulator on the internet. No ads and self hosted!
|
||||
|
||||
<p>demo: <a href=https://ethanaobrien.github.io/emulatorjs/>https://ethanaobrien.github.io/emulatorjs/</a></p>
|
||||
|
||||
<p>I have made a google chrome extension using this code <a href=https://github.com/ethanaobrien/emulatorjs-chrome-extension>here</a> - Does not need webserver.</p>
|
||||
|
||||
<h1>Where did I get this?</h1>
|
||||
<p>So I found this website called <a href=https://www.emulatorjs.com/>emulatorjs</a> and I went into inspect and downloaded the resources. I removed the ad server, and made everything work within your own domain.</p>
|
||||
<p>EMULATOR JS PEOPLE - I looked everywhere and found no terms of service on your site.</p>
|
||||
|
||||
<p>The emulator is not illegal - the rom is - I am not responsible for what people decide to do with this software.</p>
|
||||
|
||||
|
||||
<h1>IF YOU WOULD LIKE ANOTHER SYSTEM</h1>
|
||||
<p>Check if the system is on <a href=https://www.emulatorjs.com/>emulatorjs.com</a>. If it is then open an issue asking for the system you would like to emulate.</p>
|
||||
|
||||
<h1>HOW TO</h1>
|
||||
|
||||
Download this repository (Code > Download as zip) then Extract the contents
|
||||
|
||||
<p>MUST HOST ON WEB SERVER!! (I use <a href=https://chrome.google.com/webstore/detail/web-server-for-chrome/ofhbbkphhbklhfoeikjpcbhemlocgigb?hl=en>Web Server for Chrome</a> but you are welcome to use what you like)</p>
|
||||
|
||||
All of the paths are relative, all files MUST stay where they are
|
||||
|
||||
The html that has the emulator embedded in it MUST be in the same directory as all of the files.
|
||||
|
||||
If you have questions, ask me and I will clarify (use the issues tab)
|
||||
|
||||
Just so you know - You DO NOT NEED the bios for most games / systems, even if it is listed.
|
||||
|
||||
Roms can be zipped into .zip archive or .7z archive
|
||||
|
||||
<h1>Supported systems!</h1>
