• Yeah, the app loader doesn't connect to the emulator: it opens the IDE and tells it to load the app.js code.
    So it only works for apps that simply run a single file without needing any other files, otherwise it's better to disable allow_emulator.

    You can get more complex apps to work by manually uploading all parts to the emulator, which can be worth the effort for testing/screenshotting.

    (And yes, having the App Loader open the emulator directly would be nice.)
