Anyway, this game, although it runs directly on Windows, is meant to look exactly like 8-bit arcade games of the 1980s. All of that initialization stuff you see (fake in the case of Fix-It Felix Jr.) isn’t a MAME thing–MAME is simply showing you what the actual games looked like when starting up back then, which not everyone saw. MAME is running the actual vintage game code, so the initialization is real for those games, albeit on emulated rather than real arcade hardware. For a time, Fix-It Felix Jr. was made available for free play at Disney theme parks in cabinets that look just like arcade cabinets, although internally it was running on Windows PCs.
