Release notes:

If you’re not a croquet enthusiast and don’t know what a deadness board is, stop reading now, you don’t want or need this software.

Keeps track of deadness on up to six balls, using the F200’s touchscreen to make inputting deadness simple. Just click the appropriate square to mark deadness, and click the row label to clear deadness for a ball. Press select+start to clear the board, press L+R to quit.
