Hello, I recently downloaded a copy of SFA3, the parent version required to run it, Euro 980904 to be specific.

When I run MAME, the initial menu will state that it is working. However, if I attempt to run it, MAME will give me the "ROM or CHD files missing" error and refuse to run it. I can't seem to see any reason why this would happen, so any help on the matter would be appreciated.
