Save states with thumbnails

A save state stores the whole emulated machine at one moment, so you can continue from any point, not only where the game lets you save.

Available on: All 16 systems.

Related systems: NES, Game Boy, SNES, Nintendo 64, Game Boy Color, GameCube, Game Boy Advance, Nintendo DS, Wii, SG-1000, Master System, Mega Drive / Genesis, Game Gear, Dreamcast, PlayStation, PSP

How to use

  • F1 saves to the current slot, F4 loads it, F2 / F3 pick the previous / next slot (0–9).
  • The pause menu (Esc, the Guide / PS button, or Select + Start held for 0.5 s) shows a thumbnail grid of all slots.
  • In the launcher, a game's Detail → Save states lists the slots with Load and Delete.

Where states are stored

  • Each slot is slotN.state with a .json file and a slotN.png thumbnail of the game picture, in the game's save folder.
  • The save folder is found by the game's hash ID, so moving or renaming the ROM keeps its states.

Known limits

  • States of 3D systems are large: about 16 MiB (Nintendo 64), 36 MiB (Dreamcast), 40–72 MiB (PSP) and 90–120 MiB (GameCube / Wii) each.
  • GameCube / Wii states only load in the Dolphin version that made them.
  • On the Nintendo DS, loading a state also rewrites the in-game save stored in that state.

Other features

Rewind Rewind keeps a short history of the game in memory. Holding the rewind key plays it backwards at 2× speed. Fast-forward Fast-forward runs the game as fast as your PC allows while you hold the key. It is useful for long dialogue, grinding or slow intros. Run-ahead Many games react to a button press one or more frames late, even on original hardware. Run-ahead emulates ahead and rolls back each frame to hide 1–2 frames of that delay.
