### Versioning There are 3 different version name that you need to be aware of: 1. **stable** - This will be the most stable version of the emulator both code and cores will be tested before release. It will be updated every time a new version is released on GitHub. This is the default version on the Demo. 2. **latest** - This will contain the latest code but use the stable cores. This will be updated every time the *main* branch is updated. 3. **nightly** - This will contain the latest code and the latest cores. The cores will be updated every day, so this is consiterd alpha. ### CDN There is a new CDN that you can use to get any version of the emulator. The cdn is `https://cdn.emulatorjs.org/`. You can use this to get the stable, latest, nightly and any other main version by setting your `EJS_pathtodata` to `https://cdn.emulatorjs.org//data/`. ### Extensions **[GameLibrary]** *A library overview for your **ROM** folder.*
### Development: *Run a local server with:* ``` npm i npm start ```
**>> When reporting bugs, please specify that you are using the old version**
