If a user’s ROMs match FBNeo v1.0.0 but the emulator is v1.0.4, the set becomes “unknown.”
While FBNeo and MAME share a lot of history, they are completely separate projects. FBNeo uses its own specific ROM set definitions. If you download a random MAME ROM set and try to load it into FBNeo, many files will be flagged as unknown because MAME and FBNeo frequently use different dumps, chip namings, or file splits. 2. Version Mismatch (Outdated Romsets)
These are regional variants, bootlegs, or older revisions of the game. To save disk space, clone ZIP files only contain the files that differ from the parent game.

While FBNeo and MAME share a lot of history and data, they are not identical. Using a random MAME ROM set (such as MAME 0.78 or MAME 0.139) in an FBNeo core will frequently trigger "unknown" errors because the file structures have diverged over the years. 3. Missing Parent or BIOS ROMs
Arcade emulation relies on a strict 1:1 match between emulator version and ROM version.
This is usually the main, standard, or most recent revision of the game (e.g., the US or World release). It contains the core graphics, sound, and program code.
