Nothing else, the board is enough

Hotspot Arcade runs several offline party games that your friends play on their phones. The Cardputer opens its own Wi-Fi access point with a captive portal, everyone joins and plays in the browser with no app to install, and the Cardputer screen hosts the lobby, game picker and scoreboard. Original project by genkigenki on GitHub, MIT. Chipnik hosts the release binaries unchanged so you can flash them from the browser.

No internet is needed, the games run entirely on the Cardputer. This is a port of tarikbc's Hotspot Arcade for the Flipper Zero.

Firmware files come from the v0.8.0 release.

After flashing

  • The board restarts by itself when flashing is done.
  • If nothing happens, press the RST (EN) button once.
