: Frontends like LaunchBox or RetroArch sometimes try to unzip files before running them. FBNeo requires arcade games to remain in their .zip or .7z format.

It is a safety mechanism. Arcade boards are complex; running the wrong version of a graphics chip driver or CPU timing code can crash the emulator or produce garbage output. Therefore, FBNeo is strict: if it isn't a recognized version, it won't run. fbneo romset unknown
