Scoreboard

Rebuilt from the original Adobe Flash scoreboard and its Visual Basic host. Runs in a browser with no plugin. The control panel and the score screen are the same file: add ?display=1 to the address to open the score screen on its own.

Teams, formats, slides and the siren are stored in this browser on this computer. Use Menu → Export data file to move them to another machine.

Keep the file small — a short mp3 is ideal. It is stored inside this app, so the original file can be moved or deleted afterwards.
