  @bearbobs sorry for the late reply its been busy with work...did you have to host the emulationstation?....because not sure how to host from within a clickable.....Iv seen the project before but have not really done anything with it....if it runs totally client side its do able....but if it needs hosting I don't think it can be done....the nes I'm working on is a heavily modded JavaScript emulator runs totally client side i added touch support fixed up the audio and added a lot of mapper support.....one big issue is the webview out of the box is....well lacking...if you load mario you will see black squares around the clouds and other sprites...not the emulator but the webview....
