Save sync support by platform

Save sync works per game: when a game is installed, its save is uploaded to RomM and pulled back before launch, so you can carry on across devices. Standard cartridge saves work automatically. A few consoles store saves differently — this page shows what syncs for each system today, and what's planned.

Categories

	Meaning
✅	Synced today. Your saves for this system carry across devices automatically.
🔜	Planned. This save type isn't synced yet, but it fits the model and is on the way in a future release.
❌	Not synced yet. This system uses a shared memory card (one card for many games) or stores saves outside the per-game save folder, so it doesn't fit per-game sync today — planned for a later release, handled differently (see below).
⚪	No save data. This system's emulator has no in-game save to sync (you can still use save states locally).

What syncs today ✅

Standard per-game cartridge saves sync automatically. That covers the large majority of systems — Nintendo (NES, SNES, Game Boy / Color / Advance, N64, DS), Sega (Master System, Game Gear, Genesis / Mega Drive, Sega CD), PC Engine / TurboGrafx, WonderSwan, Atari Lynx, Virtual Boy, and more.

Coming soon 🔜

Per-game saves for these systems fit the sync model and are planned for a future release:

System	Notes
PlayStation — memory-card saves

A few less-common systems (some DOS, PICO-8, ST-V) may also gain support pending confirmation.

Not synced yet ❌

These consoles use a shared memory card — a single card file holds the saves for all your games — or keep saves outside the per-game save folder. A shared card can't be split per game without risking other games' saves, so it doesn't fit per-game sync today. We're looking at safe ways to handle these in a future release.

System
Dreamcast — shared VMU card
PlayStation 2 — shared memory card
GameCube — shared memory card
Neo Geo CD — shared save
Nintendo 3DS — saves kept in a separate location
PSP — saves kept in per-game folders, not single files
Arcade (MAME) — NVRAM is stored separately by the emulator

No save data ⚪

Many computer, arcade, and homebrew systems have no in-game battery save at all — there's simply nothing to sync (save states still work locally). See the full table for specifics.
