         | bird and ends the game.

           | button to get it to flap and stay aloft.

       | Cool to see this on HN today.

       | I'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.
       | 
       | It's been a blast. I didn't know much about developing on the PS1
       | and it's been fun playing code golf and trying to squeeze a more
       | modern engine out of its tiny 2MB RAM and 33.8MHz CPU.

       | [RomM](https://romm.app) added EmulatorJS support a while back,
       | pretty nice setup if you have a home server.
