Super Nintendo Emulator

Before you play

This page uses EmulatorJS with the configured snes9x core. You need your own lawfully obtained game dump; this site does not supply commercial ROMs or BIOS files.

SNES cartridge dumps may differ in headers and cartridge hardware. The accepted-extension list below describes this app, not every format supported by the underlying core.

This app does not require a BIOS selection to enable Start. That is an interface rule, not a guarantee that every game or media type is free of firmware requirements.

The emulator runtime must load before a game can start. Your selected game files are used locally, not uploaded to a game server.

Accepted files

This page accepts: .smc, .snes, .fig, .swc. These are importer extensions, not a tested game compatibility list.

Select a game file in one of the listed formats. A generic BIN or ROM extension does not identify the correct system.

ZIP containers can be extracted locally by the importer. Keep all required game files together; extraction does not convert a dump into another system or format.

Controller setup

SNES uses a D-pad, A/B/X/Y, L/R, Start and Select. Map both shoulder buttons and all four face buttons.

Use the player input settings to inspect or change bindings. Focus the game before using the keyboard, and connect a gamepad before checking its inputs. Browser recognition does not guarantee every controller or accessory works.

Known limits

Special cartridge chips and peripherals can change game requirements. A successful import is not a game compatibility test.

Performance and accuracy depend on the game, core, device and browser. No per-game compatibility or full-speed guarantee is made.

The local library may need you to re-link files when browser storage is unavailable or cleared. Keep original dumps and independent backups of important progress.

If a game does not start

If a SNES dump has an unlisted extension, verify the supported formats first; changing a suffix does not repair a malformed dump.

Check the player error message, the selected system and the original dump first. A successful extension check does not validate the file contents. See Guides for the import workflow and the core reference below for system requirements.
