To everyone trying to try this, before clicking on dropbox button you have to click on settings and set an emoji and a 3 letter identifier. then click dropbox and sign in

Super cool! I managed to select a game and get to the title screen, but then the controller stopped working? Well, it looks like the app was able to receive my button press to start the game, but no button presses on the gamepad did anything in the actual emulated state. Chrome on MacOS. None of the buttons work at all in Safari, of course.

This looks really cool, but I can't get it to work. Clicking the Dropbox button when it says "Click Dropbox button to load content" doesn't do anything. Nothing printed to web console, or anything happening in the UI.

there is also https://snes.party and the rest of that family of multiplayer apps. It's worked well in the past

Really cool! I have been using this to play old mario games and switch off with my friends like when we were kids. Enjoying the nostalgia (and making mario swim has been pretty funny)

Is it open source?

Seems like it's at a high risk of being taken down. I'd like to grab a copy to self-host before that happens.

Looks like it can't be downloaded except by family and friends of the developer?

I couldn't see anything to download - it looks all web based.

What a fascinating and well-made system. Really inspiring!

This is both High Art and cutting edge technology. Well done!
