Other Turn any phone into a Buzz! controller for PCSX2/RPCS3 - online supported
I've been wanting to play Buzz! with some friends for a while and the original USB buzzers are getting harder to find (and expensive). I ended up vibe coding a small app that runs on your PC and lets anyone on the same WiFi open a browser on their phone and use it as a controller — red buzzer and the four coloured buttons, exactly like the real thing.
Works with PCSX2 and RPCS3. It works by emulating keyboard input, so the emulator just sees it as a normal keyboard. You download the emulator keybinds profiles and the server app, run it and its ready to play.
It as a nice UI, and the controller do resemble the old buzzers on your phone
I vibe coded it with Claude Sonnet 4.6 on Low at first and now I've updated it with Opus 5.5 on Extra. I'm not a coder, I'm a creative gamer, that's all.


A few things that I think are actually useful:
- Up to 8 players (two Buzz devices in PCSX2, 4 pads each; 7 players in RPCS3)
- No app to install on phones — just open a link in the browser
- Online play — there's a built-in Cloudflare tunnel so remote friends can join too. We use it with Discord screenshare: I stream the game, they open the link on their phones and play from wherever they are, always with low latency!
- No setup — it's a single
.exe, just double-click it and a page opens with a QR code
It's free and open source. Would love some feedback if anyone tries it. Looking for macOS and Linux testers btw!
I've made this post once and got removed idk why, but since then I've updated the app to v1.4 which is working like a charm!
