Speedrun

Speedrun Mode

Speedrun mode adds split tracking and a live timer to the built-in emulator. It is new in 2.0 and still collecting feedback.

Enabling

Turn on speedrun mode from the in-game menu while playing a built-in title. The timer panel appears alongside the game and scales with the available space.

Splits

Splits are driven entirely by hotkeys so you never have to leave the game:

• Split — record the current segment and advance to the next
• Undo split — step back one segment
• Skip split — advance without recording a time
• Toggle timer — pause and resume the clock
• Reset timer — clear the run and start over

Bind these under Settings > Built-in Emulator > Controls > Hotkeys like any other hotkey. See Hotkeys for binding rules and the Player 1 limit.

Comparisons

Each split is measured against a comparison time, and the panel shows how far ahead or behind you are. The comparison is your personal best for the category once you have completed a run. Until then it is the running sum of your best segments, so a category you have never finished still tells you whether you are up or down. The sum stops at the first segment you have no time for rather than skipping the gap, since a total that jumped a segment would compare against a run nobody did.

Comparisons are rebuilt as soon as an attempt ends, so a run that beat your personal best or improved one segment is what the next attempt is measured against -- no relaunch needed.

The footer of the timer panel shows Personal Best, Session Best, Sum of Best, and the attempt number, where each of those exists.

Notes

• The timer runs on the render clock, so it stays accurate under fast-forward and pause.
• Speedrun mode is independent of RetroAchievements hardcore mode; both can be active at once.
• Split layouts and per-game customization are planned follow-ups.
