Been using this for a while. It's evolving rapidly and the team behind it is very responsive and passionate. Very excited to see this evolve over time! The only thing that it really needs going forward is more Retroarch cores ported to JavaScript, but that's an upstream problem.
We just added support for Doom and Amstract CPC in today's patch release! It's been available upstream for a while now so we just had to enable it. There's also a new update for EmulatorJS coming soon (currectly in beta testing), and I've been thinking of releasing a custom image with the nightly/beta build for testing...
