RomVault is the only ROM manager that supports tracking MIA (missing in action) ROMs. These are ROMs that are known to exist since they are included in DATs with hashes, however they have not been found or shared publicly. RomVault's MIA tracking feature allows you to see which ROMs are MIA directly from the RomVault UI.

RomVault's MIA ROM status is based on the presence of the mia="yes" tags in the DATs. Most No-Intro DATs include this tag for MIA ROMs. All DATs provided by DatVault support this special tag for MIA tracking.

The MIA tags in DatVault DATs are submitted by the community and removed automatically when MIA ROMs are found and scanned using RomVault. The community-driven approach ensures DatVault DATs contain the most up-to-date information about MIA ROMs, so there is no longer a need to refer to external wikis for MIA information.

Yes and no. Most official No-Intro DATs include the mia="yes" tag for MIA ROMs and these will correctly display MIA status without DatVault subscriber access. However, all DATs provided by DatVault support this special tag for MIA tracking. If you want to see the MIA status for all DATs that DatVault supports, then you will need to use the DATs that are delivered by DATVault.
