This is a standard file system error indicating that the emulator or software expects a file with that exact name to exist within a directory or ZIP archive, but it is missing. Common Causes
If you are using a newer version of MAME , it may require a different ROM set than older versions. The "u76" naming convention is specific to certain historical dumps of the game.
The string is broken down into several technical identifiers:
The most frequent cause is a "split" ROM set where the parent file is missing. Ensure you have the main mk4.zip file. If you are trying to run a specific revision (like Revision 3), you must have the parent ROMs and the revision-specific files in the same folder. 2. Check for CHD Files
