Replay mode

Replay mode is a read-only walk through a saved game, one state at a time. It uses the same scoring UI you already know — scoreboard, batter line, pitcher line, play log — but the state advances or rewinds in discrete snapshots rather than by typing scoring keys.

How snapshots work

Whenever you perform a scoring action — a pitch, a hit, a substitution, a runner advance — full-count saves a snapshot of the entire game state. The same snapshots that power undo are serialized to disk when you save the game, so every save file carries the pitch-by-pitch history with it.

Note

Older save files written before replay existed may not contain snapshot data. If you try to replay one, full-count prints no replay data in '<file>'. Re-save during scoring to capture it. Re-save the game once and every subsequent load will have snapshots.

Entering replay mode

Two ways:

From the load menu. On the title screen, select Load game. Highlight a save file, then press R (instead of Enter) to open it in replay mode.
From the command line.
```
full-count --load cubs-vs-sox --replay
```
Requires --load; the --replay flag only makes sense paired with a file.

The scoreboard, bases, counts, and stat lines reflect the state at whichever snapshot you're currently viewing. There's no editing — if you want to branch a game from an earlier state, switch to scoring mode and use undo instead.

What replay is useful for

Walking a friend through the game you saw.
Confirming you scored something correctly — a wild 6-4-3 or a disputed RBI.
Showing how a rally happened, pitch by pitch.
Debugging your own scoring habits against a real box score.
