 Only **one session per platform** can be active at a time, since there is a single emulator container behind it. Sessions are stored in [Valkey](../install/redis-or-valkey.md) with an atomic claim, so multiple workers stay consistent. The session is bound to the user who claimed it, and only that owner or an admin can control or release it, though an admin can force-release a stuck session.

+## Saves and save states
 
-The autosave slot is reserved for **Save & Exit**, so it can be overwritten on the next exit. Save files and states here live inside the emulator container and are **not** the same as RomM's [per-user saves and states](saves-and-states.md) from in-browser play.
+**Save states** are the emulator's own quick-save slots: numbered manual slots plus a dedicated autosave slot per platform (see the table above). The autosave slot is reserved for **Save & Exit** and is overwritten on the next exit.
+
+When a session ends, RomM copies your states off the container into your library and keeps a thumbnail for each. They then show up in the player's **Resume from state** panel next time you launch that game, where you can pick one to carry on from instead of booting fresh. RomM keeps the newest states and prunes the rest once you pass `STREAMING_STATE_HISTORY_LIMIT` (default `50`) per game.
+
+These streaming states are stored separately from RomM's [per-user saves and states](saves-and-states.md) from in-browser play.
+
+## Memory cards
+
+On platforms with a memory card (**PS2** and **GameCube**), you can opt a container into whole-card sync with `memory_card_sync: true`. The card then lives in your RomM library rather than on the container: RomM loads your card in when a session starts, copies it back when you exit, and leaves the container's slot blank in between. The newest card loads by default, and you can keep several and switch between them from **Manage memory cards** in the player.
+
+Because each session starts from your library, the first time RomM uses a container that already has a card on it, it stops and asks what to do:
+
+- **Import this card** brings the existing card into your library as a new memory card.
+- **Start fresh** erases the container's card. This asks for confirmation, since it cannot be undone.
+
+RomM records your answer per container, so it only asks once.
+
+<!-- prettier-ignore -->
+!!! warning "Playing on the container directly"
+    Syncing only happens around a RomM streaming session. If you play on the emulator container directly, outside RomM, those saves and cards stay on the container and are not pulled into your library. A later RomM session loads your library's copy over them, so make your progress through RomM to keep it.
