Rewind

Rewind

Rewind lets you hold a hotkey to roll gameplay back and retry a moment -- handy for missed jumps, bad dodges, or boss hits. It works by keeping a rolling buffer of recent emulator states in memory.

This page covers rewind for the Built-in Emulator.

Default state

Rewind is on by default. On heavier systems the continuous cost of serializing state makes it impractical, so Argosy turns it off automatically and removes it from the per-platform settings UI. Affected systems:

• GameCube, N64, N64DD
• PS1, PS2
• Saturn, Dreamcast
• PSP, NDS, DSi
• 3DO, Jaguar, Jaguar CD

To try rewind on one of these anyway, set a per-platform override in Settings > Platforms > [Platform] > Built-in Overrides.

Configuration

Settings > Built-in Emulator > A/V & Performance exposes:

• Enable Rewind -- global on/off.
• Rewind buffer duration -- 5, 15, 30, or 60 seconds. Default 15s. Longer buffers use more RAM.
• Rewind speed -- 1x, 2x, or 4x playback speed while rewinding. Default 1x.

Rewind is a hold-to-rewind action. Press and hold the rewind hotkey (see Hotkeys) to scrub backwards; release to resume normal play.

Restrictions

• Netplay session -- rewind is silently ignored. A rollback that rewrites shared state would desync the other player.
• RetroAchievements hardcore mode -- rewind is blocked and shows a notice. Hardcore requires a clean run.
