A little help. More time to play.
Getting started
Browse or search the library, choose a game and press Start playing. No account is required. Only the selected game and core are loaded; some source collections require additional dependencies or a different supported core.
Keyboard and controllers
Arrow keys move; X and Z are the main action buttons. Enter is Start and V is Select (often the arcade coin button). Extra buttons and controller mappings depend on the system. Check the emulator control settings and any game-specific notes.
Keep your progress
Use Save snapshot, then wait for confirmation. This release persists ReplayCove snapshots; an in-game save alone is kept only in this running tab. Automatic checkpoints are enabled only for configurations explicitly marked as restoration-tested. Export important progress before clearing browser data.
Restoring a snapshot
Snapshots are matched to the exact game variant, file fingerprint and core profile. After loading a snapshot, confirm that the expected progress is on screen. A file upload or successful write alone does not prove a game restored correctly.
Accounts and favorites
Guest favorites stay in this browser. A verified account adds cross-device favorites. Existing browser favorites are merged only after you choose to do so, and never replace the whole account list. Normal play does not depend on login or email availability.
Account snapshot copies
From Your snapshots, choose Copy to account. These are separate revisions, not automatic two-way synchronization. Each snapshot is limited to 16 MiB, with 30 copies per game/core profile and 128 MiB per account. Local and exported copies remain independent.
A game is slow or will not start
Read the visible error and open Performance and launch diagnostics. Compare the same scene in a window and fullscreen, then export the report. A ZIP that opens successfully may still be the wrong ROM set for the selected core; BIOS, parent archives and disc layouts are game-specific.
Playing together
Two-player listings refer to source metadata and the same device/screen, not remote multiplayer rooms. Whether players act simultaneously, alternate turns or cooperate depends on the game. Connect a controller and press a button for browser detection.
