: The official arcade cabinets Disney built for movie promotion were actually running a Windows-based executable (.exe)
The emulator crashed. The window vanished.
While there is no MAME ROM, there is a very popular created by homebrew developers.
The version of Fix-It Felix Jr. seen in the film was a fully playable, pixel-perfect game built by Disney’s technical team. A small number of actual arcade cabinets were produced for promotional purposes and to sit in Disney theme parks (like the DisneyQuest arcade).

Technically, an "original 1982 ROM" for MAME does not exist because the game never existed in 1982. However, there are several ways it has been made "real":
Forget MAME. Use directly. The original ffj.exe runs perfectly on modern Windows. Just double-click it.
