Neo Geo Emulator

Before you play

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

Neo Geo arcade dumps are ROM sets: a ZIP can contain multiple chip files. FBNeo expects an appropriate set and may require matching BIOS files.

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: .neo, .bin, .zip. 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 is passed through as a game archive on this page. Preserve its internal filenames and required contents.

Controller setup

Neo Geo uses a joystick and four action buttons. Arcade games also need coin and Start inputs.

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

This page does not offer a separate Neo Geo BIOS picker. Set dependencies must suit the configured FBNeo core; a ZIP accepted by the importer may still fail to boot.

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

For missing-ROM errors, check the set version, parent-set dependencies and Neo Geo BIOS requirements in the FBNeo documentation.

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.
