How it works


The RomBase Manager unlike the Rom Manager is a tool for maintaining Metropolis Launcher's internal Rom Database.


The RomBase ( is the underlying database for Metropolis Launcher to automatically link games to MobyGames metadata.


Note: Using the RomBase Manager is not supposed to be performed by individual end-users. Ignore the RomBase Manager if you don't know what you're doing or haven't been told to use it.


After selecting a platform, you get a list of all files in the database on the left side. The right side lists all MobyGames releases for the selected platform.


You can link a MobyGames release to one or more selected files by double clicking the MobyGames release.


The context menu (right click) of the files list provides the following menu items:




hmtoggle_plus1[1] Copy Name to Clipboard


Copies to the file name to your clipboard.


hmtoggle_plus1[2] Add Games from ...


The RomBase Manager allows adding file entries from multiple fileformats:


DAT (XML): an XML file from a DAT, converted by datutil
DAT with serial tag: the identifier will not be CRC, SHA1 or MD5 - a platform-specific serial per game will be used, the DAT must also be converted to XML by datutil
CSV: custom generated CSV text files from web sources


hmtoggle_plus1[3] Delete N entries


Delete selected (using SHIFT or CTRL) file entries from the RomBase


hmtoggle_plus1[4] Detect MobyGames Links...


You can use this menu item to automatically find best candidates by comparing filenames to the names of the Moby Releases.


After the analysis, you get a preview of the results where you can decide for which games the linking should be applied.
