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/<version>/data/.

PSP is not yet supported. Some of y'all may have seen that I pushed a "beta" ppsspp core, but this core is not ready for daily use. It still crashes randomly and any games that use 3d (so like, all of them) will just have a white screen (and might just crash). Do not open issues related to the "psp" core.
