I run Afterplay (https://afterplay.io). It's a game emulation platform where you bring your own games. It took 18 months from first line of code to 2K. It's now my full time job :)
This looks super awesome! I just tried it in Chrome however, and after a minute of playing the game it just drops me back to the game library screen. Love the idea though!
Yeah, it was happening on Super Mario Kart. I just tried Super Mario RPG and didn't have any issues. Let me know if I can get you more info or help with a repro.
