I made a custom OBS browser source (webpage that can display in the streaming software).
It's running WasmBoy, a GameBoy emulator that can run in the browser. Alongside the emulator, I'm subscribing to relays and parsing zaps + chat messages and feeding the inputs into the emulator.
I'm also using a tool I call Nostr Stream Manager that I made to help broadcast my kind 30311 live event notes from OBS.
The GameBoy + other tools are available for anyone to use! https://streambrah.com https://github.com/satsgg/streambrah
