[RomM](<a href="https:&#x2F;&#x2F;romm.app" rel="nofollow">https:&#x2F;&#x2F;romm.app</a>) added EmulatorJS support a while back, pretty nice setup if you have a home server.

If you&#x27;re not familiar with RetroArch I highly recommend checking it out. Very cool tech.

Doesn&#x27;t look like keyboard input is supported on the flappy bird demo on the site?

Cool to see this on HN today.<p>I&#x27;m currently using RetroArch in the browser along with the original Sony devkit and a custom hot-reload C dev server to develop a PS1 game engine. I started with EmulatorJS but ran into issues with its prebuilt cores while trying to get audio streaming working, and decided to just work with libretro directly.<p>It&#x27;s been a blast. I didn&#x27;t know much about developing on the PS1 and it&#x27;s been fun playing code golf and trying to squeeze a more modern engine out of its tiny 2MB RAM and 33.8MHz CPU.

Looks cool, but too bad it doesn&#x27;t support PS2 :(
